Unpacking the Tape Drive  
The tape drives packaging is designed to protect the tape  
drive from shock, vibration, moisture, and electrostatic  
discharge (ESD). Save all original packaging in case you  
need to repack or ship the tape drive.  
CAUTION  
If the temperature of the room in which you are  
unpacking the tape drive differs from the storage  
location by 15° C (27° F) or more, let the tape drive  
acclimate in its packaging to the room environment  
for at least 12 hours before opening the box. This  
helps prevent condensation damage to the drive.  
After you unpack the tape drive, check the contents of the  
carton against the packing list and inspect the tape drive  
for possible damage. If a part is missing or the tape drive  
is damaged, notify the carrier and your vendor  
immediately.  
Note: If the tape drive has been stored for more than six  
months, follow the instructions on page 21 when  
applying power for the first time. (Check the  
MLCH label on the top of the tape drive to find  
out when the tape drive was manufactured.)  
Ensuring ESD Protection  
Follow these procedures to protect the tape drive from  
electrostatic discharge (ESD):  
Leave the tape drive in its antistatic bag until you are  
ready to install it.  
Use an antistatic mat and grounded static protection  
wristband. If a mat and wristband are unavailable,  
10  
EXB-8500/EXB-8500c  
306261  
 
discharge static electricity from your body before  
handling the tape drive. (Touch a known grounded  
surface, such as your computers metal chassis.)  
If you must lay the tape drive down, place it into or  
on top of the antistatic bag.  
Setting the SCSI ID  
After unpacking the tape drive, you can change the tape  
drives default SCSI ID, if necessary. Do not use SCSI ID  
7. This SCSI ID is used by your SCSI adapter card.  
You can use any of the following methods to set the ID:  
Set the DIP switches on the rear of the tape drive.  
Attach jumpers (shunts) to the pins on the tape  
drives SCSI ID jumper block. Jumpers are already  
installed on the jumper block when the tape drive is  
shipped.  
Connect a remote switch to the SCSI ID jumper block  
on the back of the tape drive.  
These methods are explained in the following sections.  
Important  
If you are using a remote switch or jumpers to set  
the SCSI ID, make sure that the DIP switches are set  
to SCSI ID 0 (the default). Similarly, if you are using  
the DIP switches to set the SCSI ID, make sure that  
the remote switch or jumpers are set to SCSI ID 0.  
If you set both the DIP switches and the remote  
switch to a particular SCSI ID, the actual SCSI ID  
will be the logical OR of the two settings. For  
example, if the remote switch is set for SCSI ID 1  
and the DIP switches are set for SCSI ID 2, the  
actual SCSI ID will be 3.

Setting the SCSI ID with the DIP Switches  
To set the SCSI ID using the DIP switches, follow these  
steps:  
1. Locate the SCSI ID DIP switches on the back of the  
tape drive, as shown in Figure 1.  
2. Change the DIP switch settings to the correct SCSI  
ID for your configuration. Figure 2 shows the  
settings for SCSI IDs 0 through 7.  
3. Make sure that the remote switch or jumpers are set  
to SCSI ID 0.

Setting the SCSI ID with Jumpers  
To set the SCSI ID using jumpers, follow these steps:  
1. Locate the SCSI ID jumper block on the back of the  
tape drive, as shown in Figure 1.  
2. Install the jumpers on the jumper block to obtain  
the correct SCSI ID for your configuration. Figure 3  
shows how to position the jumpers for SCSI IDs 0  
through 7.  
3. Make sure that the DIP switches are set to SCSI ID 0.

Setting the SCSI ID with a Remote Switch  
If you want to set the SCSI ID remotely, you can attach a  
remote switch assembly (not provided with the tape  
drive) to the tape drives SCSI ID jumper block. To set the  
SCSI ID with a remote switch, follow these steps:  
1. Locate the SCSI ID jumper block on the back of the  
tape drive, as shown in Figure 1.  
2. If necessary, remove the jumpers from the pins.  
3. Connect a remote switch to the jumper block.  
Ensure that the remote switch is no more than  
30.5 cm (12 inches) from the jumper block. See  
Table 1 on page 9 for connector requirements.  
4. Make sure that the DIP switches (Figure 1) are set  
to a SCSI ID of 0.  
5. Change the settings on the remote switch to the  
correct SCSI ID for your configuration. The switch  
settings should emulate the jumper positions shown  
in Figure 3.  
Note: For specific information about pin  
assignments for the SCSI ID jumper block,  
refer to the EXB-8500 and EXB-8500c Product  
Specification.  
Preparing the Tape Drive for the SCSI Bus  
The SCSI bus that you attach the tape drive to must be  
terminated correctly to ensure proper operation. The  
devices that are physically located at each end of the SCSI  
cable must have terminators installed. All other devices  
on the SCSI cable must not have terminators installed.  
If the tape drive will be located at the end of the SCSI bus,  
you must terminate the tape drive. The procedure you  
use depends on whether the tape drive uses a  
single-ended or a differential SCSI configuration.  
14  
EXB-8500/EXB-8500c  
306261  
 
Terminating a Single-Ended Tape Drive  
The single-ended tape drive includes two single in-line  
package resistor terminators (R-packs) that can be left in  
place if the tape drive terminates the SCSI bus.  
CAUTION  
The R-packs must be removed if the tape drive does  
not terminate the SCSI bus or if you plan to use an  
external SCSI bus termination.  
Optional External Termination  
If desired, you can terminate the single-ended tape drive  
externally by removing the R-packs from the back of the  
tape drive and installing an external terminator. Exabyte  
recommends a Methode Electronics, Inc. dataMate  
DM103-02-0 single-ended external terminator.  
Removing the R-Packs  
To remove the R-packs, follow these steps:  
1. Locate the two R-packs on the back of the tape  
drive, as shown in Figure 4.  
Figure 4 Location of R-packs (single-ended  
configuration)  
December 1993  
EXB-8500/EXB-8500c  
15  
 
2. Using a pair of flat-nose wiring pliers, grasp each  
R-pack at the center and pull it straight out. Be  
careful not to squeeze the pliers too tightly or you  
may break the R-pack.  
Replacing the R-Packs  
If you need to put the R-packs back in the tape drive,  
make sure that pin 1 of each R-pack is aligned with pin 1  
of the socket and that no pins are bent. As shown in  
Figure 4, the writing on the R-pack should face upward.  
Pin 1 of the R-pack is marked with a colored line or dot  
and should line up with the right side of the socket.  
CAUTION  
If you replace an R-pack, be sure to use the correct  
type to avoid damaging the tape drive. The tape  
drive uses two 10-pin, 9-resistor R-pack  
terminators, rated at 110 ohms. Replacement  
R-packs are available from Exabyte (part number  
002228).  
Terminating a Differential Tape Drive  
The differential tape drive does not include internal  
terminators. If a differential tape drive terminates the  
SCSI bus, it must be terminated externally. See page 9 for  
information about the recommended terminator.  
Connecting the SCSI Cable  
The tape drive uses a standard 50-pin single-ended SCSI  
cable connector. Push the keyed connector on the SCSI  
cable on to the SCSI connector on the back of the tape  
drive. The connector is keyed so that it can be connected  
only one way.  
Figure 5 shows the location of the SCSI connector.  
Note: The SCSI cable for connecting the tape drive to  
the host is not provided with the tape drive. Refer  
to page 37 for information about the requirements  
for the SCSI cable.

Installing the Tape Drive in a PC Drive Bay  
If you are planning to mount the tape drive in a full-high  
PC drive bay, follow the guidelines in this section.  
Otherwise, refer to Appendix A for installation  
requirements, then resume reading on page 20,  
“Performing the Initial Power On.”  
Before beginning, prepare your computer as follows:  
1. Turn off the computer and attached devices.  
2. Unplug the power cord.  
3. Remove the computers cover as described in your  
computer owners manual.  
4. Remove the cover plate(s) from the drive bay(s) you  
intend to use. Refer to your computer owners  
manual for instructions.  
Note: For some computers you may need to use two  
half-high drive bays to accommodate the tape  
drive.

5. If necessary, remove one of the floppy disk drives  
to provide an empty full-high drive bay for the tape  
drive.  
CAUTION  
If you remove floppy disk drive B to install the tape  
drive, be sure to change your system configuration  
to reflect this. Refer to your computer owners  
manual for details on running the systems setup  
program.  
Mounting Procedure  
Follow these steps to mount the tape drive:  
1. Check for the presence of a load resistor in the  
computer. If it is present, disconnect the load  
resistor cable from the power supply. Refer to your  
computer owners manual for more information.  
2.  
Use #6 32 screws to attach two slide rails to the  
sides of the tape drive (see Figure 6). The tapered  
end of each rail should point toward the rear of the  
tape drive.

3. From the front of the computer, thread the SCSI  
cable into the computer through the open bay. Slide  
the tape drive into the bay until the faceplate is  
flush with the front of the bay.  
4. Secure the tape drive to the drive bay as instructed  
in your computer owners manual.  
5. Connect the SCSI cable to your SCSI adapter card  
(see Figure 7).

1
grounding wire fitted with a 4-inch female spade  
connector to the ground tab on the back of the tape  
drive. Or, use an M3-0.5 6 mm self-tapping screw  
to connect the wire to the grounding hole. The  
ground tab and grounding hole are shown in  
Figure 8.  
December 1993  
EXB-8500/EXB-8500c

7. Connect power cable from the power supply to the  
4-pin power connector on the back of the tape drive.  
CAUTION  
Make sure that the PC power is off before you  
connect the cable.  
Do not force the plug into the connector. The keyed  
edges of the plug and the connector must match.  
8. Replace the computers cover.  
Performing the Initial Power On  
The procedure you use to perform the initial power on  
depends on how long the tape drive has been stored. If  
you are not sure how long the tape drive has been stored,  
check the MLCH (machine level control history) label on  
the top of the tape drive to find out when the tape drive  
was manufactured. Although the tape drive may have  
been operated since it was manufactured, for the purpose  
of the initial power on, assume that it has been stored  
throughout this period.  
Tape Drive Stored for Less Than Six Months  
If the tape drive has been stored for less than six months,  
the only step you need to perform for the initial  
power-on is to apply power to the tape drive.  
20  
EXB-8500/EXB-8500c  
306261  
 
When power is applied, the tape drive performs its  
power-on initialization and self-test (POST). Assuming  
that no data cartridge is loaded and that the tape drive is  
connected correctly, POST takes about 65 seconds, as  
follows:  
During the first part of POST, both the amber and  
green LEDs are lit.  
During the second part of POST, various  
combinations of the LEDs may be lit, depending on  
whether the tape drive is connected to the SCSI bus  
and whether a data cartridge is loaded.  
After the power-on initialization and self-test have  
completed, both LEDs will be turned off if there is no  
data cartridge loaded. If a data cartridge is loaded,  
the green LED will remain on.  
Important  
If the amber LED does not go out after the  
power-on initialization and self-test are complete,  
an error has occurred. Contact your vendor.  
When POST completes, the tape drive is ready for normal  
operation.  
Tape Drive Stored for Six Months or More  
If the tape drive has been stored for six months or more,  
perform the following steps using your backup software  
to ensure that the tape drives internal lubrication is  
properly distributed:  
1. Apply power to the tape drive. The tape drive  
performs its POST as on page 20.  
2. Locate a data cartridge that does not contain any  
valuable information. Set the write-protect switch  
to write enabled (see page 26).  
3. Press the unload button on the front of the tape  
drive. Insert the data cartridge with the label side  
up and the write-protect switch facing you.  
December 1993  
EXB-8500/EXB-8500c  
21  
 
4. Push the door shut and wait while the tape drive  
loads the tape and positions it at LBOT. When the  
amber LED is off and the green LED is on, the tape  
is loaded and the tape drive is ready.  
5. Write approximately 500 MBytes of data to the tape.  
6. Read the data written in step 5.  
7. Repeat steps 5 and 6 at least two times or for two  
hours (whichever is greater).  
Note: If errors occur, reset the tape drive and  
repeat steps 5 though 7 as appropriate. If the  
error recurs, contact your vendor.  
When you have completed step 7, the tape drive is ready  
for normal operation.

Reading the LEDs  
The tape drive uses two LEDs to indicate its operating  
states. The LEDs indicate the following general  
conditions:  
The green LED indicates that the tape drive can  
accept a tape access command.  
The amber LED indicates SCSI bus activity and tape  
drive error conditions

Table 2 shows specific combinations of LEDs that may  
occur during tape drive operation. You may occasionally  
observe LED combinations and sequences not described  
in Table 2. These other combinations represent special or  
unusual conditions that are beyond the scope of this  
table. (For example, a fairly complex LED sequence  
occurs when you load new microcode from tape.)

Selecting Data Cartridges  
By selecting high-quality data cartridges and storing  
them properly, you can expect a long shelf-life and  
optimal data integrity from them. High quality tapes also  
help maintain tape drive reliability by minimizing wear  
on the recording heads.  
Choosing High-Quality Data Cartridges  
Available from Exabyte, EXATAPE™ 8mm Data  
Cartridges are formulated specifically for use in Exabyte  
products. EXATAPE data cartridges reduce head and  
tape path wear and have a shelf life exceeding 30 years  
when used according to recommendations. Available in  
three sizes (112m, 54m, and 15m), EXATAPE data  
cartridges are the only data cartridges recommended for  
use with all Exabyte products.  
CAUTION  
Exabyte strongly recommends that you use  
EXATAPE data-grade metal-particle media in the  
tape drive.  
Never use video-grade tape for data storage.  
Video-grade tape can be less accurate than  
data-grade tape when recording high-density data  
and more abrasive to tape drive recording heads. In  
particular, Exabyte strongly discourages use of the  
following types of video-grade tapes:  
“Extended length” (such as 135-, 140-, and  
150-minute tapes)  
Hi-8 metal particle (MP), metal evaporative  
(ME), or barium ferrite (BaFe) tapes. These tapes  
will be ejected automatically by the tape drive.

Setting the Write-Protect Switch  
EXATAPE™ 8mm data cartridges are equipped with a  
write-protect switch, shown in Figure 10, to prevent data  
on the tape from being unintentionally overwritten.  
Before loading a data cartridge in the tape drive, ensure  
that the write-protect switch is set correctly for the  
desired operation. You can use a ball-point pen or similar  
instrument to set the write-protect switch as follows:  
To write protect the data cartridge, move the  
write-protect switch away from the edge of the data  
cartridge. If the red tab is visible, the cartridge is  
write protected and cannot be written to or erased.  
To write enable the data cartridge, move the  
write-protect switch toward the edge of the data  
cartridge. If the red tab is not visible, the data  
cartridge is write enabled and can be written to or  
erased.

Loading a Data Cartridge  
To load a data cartridge into the tape drive, follow these  
steps:  
1. Ensure that the write-protect switch has been set  
correctly for the desired operation, as explained on  
page 26.  
2. If you have just powered on the tape drive, be sure  
that the green LED is off, indicating that the tape  
drive has passed its power-on self-test and is ready  
to load the data cartridge.  
3. If necessary, press the unload button to open the  
door on the tape drive.  
4. Insert the data cartridge into the tape drive with the  
label side up and the write-protect switch facing  
you.  
5. Gently close the door. The tape drive automatically  
loads the data cartridge and indicates ready status  
(green LED on).  
Note: Most tape drives load the data cartridge  
automatically. However, your application  
software may disable the autoload function. If the  
data cartridge does not go to the ready state after  
you close the door, consult your software  
documentation for information.  
Unloading a Data Cartridge  
Unload Button  
The unload button is the only operator control on the  
tape drive. It is used to unload the tape from the tape  
drive.  
The unload button can also be used to clear servo and  
other errors. If a servo or hardware error occurs, press the  
unload button to reset the tape drive. Then, if necessary,  
December 1993  
EXB-8500/EXB-8500c  
27  
 
wait a few seconds and press the button again to eject the  
tape.  
To unload a data cartridge, press the unload button on  
the tape drives front panel. The tape drive completes the  
current operation, writes any buffered data to tape,  
unloads the tape from the tape path, and ejects the  
cartridge.  
Note: Some tape drives are configured to eject the tape  
immediately when the unload button is pressed.  
Refer to the EXB-8500 and EXB-8500c Product  
Specification if you have a tape drive configured in  
this way.  
Error During Unload Procedure  
If an error exists before or during the unload procedure,  
the unload sequence will be suspended and the amber  
LED will flash. If the unload button is pressed again, the  
unload sequence will be reattempted; however,  
unwritten data in the buffer will not be written to tape.  
The buffer and errors will be cleared.

3 Preventive Maintenance  
The only routine maintenance required by the tape drive  
is regular cleaning of the tape drive heads and tape path.  
Use only an Exabyte or Exabyte-approved 8mm Cleaning  
Cartridge. Proper storage and maintenance of your data  
cartridges will maximize the shelf life of your tapes and  
assure data integrity.  
Important  
Using a cleaning method other than the Exabyte  
8mm Cleaning Cartridge or an Exabyte-approved  
cleaning cartridge will void the warranty for the  
tape drive and can lead to premature head wear.  
Determining When to Clean the Tape Drive  
You should clean the tape drives heads and tape path  
after every 30 tape motion hours. This cleaning  
frequency is independent of the format in which you  
write and read data. However, if you are using the tape  
drive in a particularly dirty environment, or if you  
operate it infrequently, you may want to clean the tape  
drive more often than every 30 tape motion hours.  
Some backup software programs may notify you when  
the tape drive needs cleaning. Refer to the documentation  
for your backup software for more information.  
Note: The tape drive keeps track of its tape motion  
hours internally. To determine when the tape  
drive needs to be cleaned, issue a REQUEST  
SENSE (03h) command and look at the setting of  
the CLN and CLND bits (byte 21, bits 3 and 4). If  
the CLN bit is set to 1, the tape drive needs to be  
cleaned. This bit is reset to 0 when you perform a  
successful cleaning cycle. The CLND bit is set to 1  
when the tape drive has been cleaned and is reset  
to 0 when the next REQUEST SENSE command is  
received.

Using the 8mm Cleaning Cartridge  
CAUTION  
To prevent contamination of the tape drive and  
damage to the heads, do not use the cleaning  
cartridge for more than the number of cleaning  
cycles specified on the cartridge label. Reusing the  
material in the cleaning cartridge will redistribute  
contaminants previously removed from the tape  
path. Discard the cleaning cartridge after you have  
used it for the specified number of cleaning cycles.  
To use the cleaning cartridge, follow these steps:  
1. Apply power to the tape drive. When the power-on  
self-test is complete, press the unload button and  
remove any data cartridge from the tape drive.  
2. Check the usage record on the label of the cleaning  
cartridge to make sure that there is at least one  
cleaning cycle remaining (see Figure 11). If there are  
no cleaning cycles remaining, discard the cleaning  
cartridge and use a new one.  
Figure 11 Exabyte 8mm Cleaning Cartridge with label  
showing cleaning cycles left  
30  
EXB-8500/EXB-8500c  
306261  
 
3. Insert the cleaning cartridge in the tape drive and  
close the door.  
4. The cleaning cycle is performed automatically by  
the tape drive and takes approximately 38 seconds.  
When the cleaning cycle is complete, the cleaning  
cartridge is automatically unloaded and ejected  
from the tape drive.  
Important  
If there are no more cleaning cycles remaining for  
the cleaning cartridge, the tape drive ejects it  
without completing the cleaning cycle.  
Note: To confirm that a cleaning was done, issue a  
REQUEST SENSE (03h) command and check  
the setting of the CLND bit. If set to 1, this bit  
indicates that the cleaning was successful. A  
setting of 0 indicates that the cleaning was  
not done.  
5. If the cleaning cycle was successful, record the date  
the cleaning was performed on the cleaning  
cartridge label. Store the cleaning cartridge for  
future use if it still has cycles remaining. Or,  
discard it if no more cleaning cycles remain.  
Caring for Data Cartridges  
To maximize the shelf life of your tapes and assure data  
integrity, follow these guidelines when storing data  
cartridges:  
Place a label or other reference information on the  
cartridge adjacent to the write-protect switch.  
Store cartridges in a cool, non-magnetic environment.  
Follow the cartridge manufacturers specifications  
for storage temperature and other environmental  
requirements. Do not allow the temperature and  
humidity in the storage environment to fluctuate.  
December 1993  
EXB-8500/EXB-8500c  
31  
 
Keep the storage location as free of airborne  
particulates as possible. To eliminate obvious  
sources of particulates, do not permit anyone to smoke,  
eat, or drink near the storage area, and do not store  
cartridges near a copier or printer that may emit  
toner and paper dust.  
Store data cartridges as soon as possible after you  
have written data to them. mmediate storage helps  
avoid many of the conditions that can damage tapes,  
such as temperature and humidity fluctuation,  
particulate contamination, and excessive handling.  
Store data cartridges with the write-protect switch  
in the protected position. See page 26.  
Store each cartridge on one of its long edges, not  
flat on its side (see Figure 12). When a data cartridge  
is stored on its side, the tape inside the cartridge is  
actually on its edge. In this position, stress is placed  
on the tape edges and can lead to tape damage. For  
the same reason, never stack cartridges on top of  
each other or lean them at an angle for extended  
periods of time.  
Figure 12 Do not store a data cartridge on its side  
32  
EXB-8500/EXB-8500c  
306261  
 
Replacing Data Cartridges  
Approximately once each year, you may want to run  
each tape through a full pass and check its error statistics.  
If errors have increased significantly since the previous  
test or if they exceed a certain predetermined threshold,  
you should re-archive the data to a new tape and discard  
the old tape.

carton (single-pack) or with four drives per carton  
(four-pack). Figure 13 on page 34 shows the single-pack  
carton and packing materials.  
CAUTION  
To avoid damaging the tape drive and voiding  
your  
warranty, be sure to use the original shipping  
materials (or replacement materials obtained  
from Exabyte) when repacking and shipping  
the tape drive.  
To ensure that the packaging meets the required  
specifications, do not modify the packaging in  
any way. The shipping carton and packing

Appendix A Installation Requirements  
This appendix provides specific installation requirements  
for the tape drive. It also provides guidelines for the  
following tasks:  
Selecting the correct SCSI cable and connector (pages  
37 and 38)  
Attaching the tape drive to a frame (page 38)  
Providing chassis grounding (page 40)  
Connecting the tape drive to the power supply (page  
40)  
If you have already installed the tape drive in a PC, you  
can skip this appendix.  
SCSI Cable Requirements  
The SCSI cable for connecting the tape drive to the host is  
not provided with the tape drive. You must provide a  
cable that complies with the appropriate safety and  
regulatory agency requirements. To comply with FCC,  
Canadian DOC, and VDE limits, the tape drive requires  
shielded cables when the cables are external to the  
mounting enclosure.  
General Requirements  
Use a 50-conductor flat cable or 25-signal twisted pair  
cable. A minimum conductor size of 28 AWG is  
recommended to minimize noise effects and ensure  
proper distribution of terminator power.  
Ideally, to match the cable terminators, the cable should  
have a characteristic impedance of 122 ohms (differential)  
or 132 ohms (single-ended). However, since cables with  
this high of a characteristic impedance are not generally  
available, somewhat lower impedances are acceptable. A  
characteristic impedance of 100 ohms ± 10% is  
recommended for unshielded flat or twisted-pair ribbon  
cable. A characteristic impedance greater than 90 ohms is  
recommended for shielded cables.  
December 1993  
EXB-8500/EXB-8500c  
39  
 
Note: To minimize discontinuities and signal  
reflections, ensure that cables used on the same  
bus have the same impedances.  
Cable Length Requirements for Differential  
Configurations  
For differential SCSI configurations, ensure that the sum  
of all the SCSI cable lengths does not exceed 25.0 meters  
(82.02 feet). A stub length of no more than 0.2 meters  
(8 inches) is allowed off the mainline interconnection  
within any connected equipment. The stub length within  
the tape drive is less than 50 mm (1.97 inches).  
Cable Length Requirements for Single-Ended  
Configurations  
For single-ended SCSI configurations, ensure that the  
sum of all the SCSI cable lengths does not exceed 6.0  
meters (19.68 feet). A stub length of no more than 0.1  
meters (4 inches) is allowed off the mainline  
interconnection within any connected equipment. The  
stub length within the tape drive is less than 50 mm  
(1.97 inches).  
SCSI Cable Connector  
To connect the tape drive to the SCSI bus, use a 50-pin  
female ribbon cable connector (AMP™ No. 1-746285-0 or  
equivalent). The tape drives SCSI connector is located at  
the rear of the tape drive. The connector is a 50-pin male  
ribbon cable connector, consisting of two rows of 25 pins  
with adjacent pins 2.54 mm (0.1 inch) apart. For  
information about the specific SCSI connector pin  
assignments for differential and single-ended tape drives,  
refer to the EXB-8500 and EXB-8500c Product Specification.  
Attaching the Tape Drive to a Frame  
The main housing of the tape drive includes two sets of  
mounting holes (one set on the sides and one set on the  
bottom, as shown in Figures 14 and 15) to allow for a  
number of mounting positions. These mounting holes  
accommodate #6-32 screws. Refer to the EXB-8500 and  
40  
EXB-8500/EXB-8500c  
306261  
 
EXB-8500c Product Specification for detailed information  
about the spacing of these mounting holes.  
When mounting the tape drive, follow these guidelines:  
The mounting location must meet the environmental  
requirements discussed in the EXB-8500 and  
EXB-8500c Product Specification. These requirements  
specify limits for operating temperature, humidity,  
airflow, particulate contamination, shock, and  
vibration.  
The tape drive must be mounted solidly and  
securely. To assure reliability, there must be no  
distortion of the tape drives metal housing. Do not  
install the tape drive in such a way that its frame is  
unsupported. For example, do not hang the tape  
drive by an edge.  
Use either the four mounting holes on the sides or the  
four mounting holes on the bottom (“A” or “B,” as  
shown in Figures 14 and 15). Using combinations of  
mounting holes from different sets may distort the  
frame.  
Objects such as screw heads, cables, or adjacent  
devices must not press against the frame of the tape  
drive.  
The ventilation slots at the sides and top of the tape  
drive must be free of obstruction so that adequate  
airflow is provided.  
There must be sufficient space to access and operate  
the front panel controls.

Chassis Grounding (optional)  
If additional chassis grounding is desired, connect a  
14-inch female spade connector to the ground tab at the  
rear of the tape drive. Or, connect an M3-0.5 6 mm  
self-tapping screw to the grounding hole. The ground tab  
and grounding hole are shown in Figure 8 on page 19.  
42  
EXB-8500/EXB-8500c  
306261  
 
Note: The power supply returns are connected to the  
chassis, so you cannot isolate logic common  
ground from chassis ground.  
Power Cable Connector  
The tape drive operates from standard +5 VDC and +12  
VDC supply voltages; it cannot use external AC power.  
Safety agency certification requires that the supplied  
voltage be from a Safety Extra-Low Voltage source (per  
IEC 950). Refer to Appendix B for tape drive power  
specifications.  
CAUTION  
The tape drive does not provide any overvoltage or  
over current protection. For this reason, be certain  
that the power is off before connecting the tape  
drive to a power supply.  
The power connector used in the tape drive is compatible  
with power connectors used for standard 5.25-inch  
devices. To connect the tape drive to a power cable, use  
an AMP 1-480424-0 series or equivalent female connector.  
For information about the specific power connector pin  
assignments, refer to the EXB-8500 and EXB-8500c Product  
Specification.
