1 Introduction
This manual provides information about installing, operating, and maintaining
the EXABYTE®Tabletop 8mm Cartridge Tape Subsystem.
1.1 About the Tabletop Cartridge Tape Subsystem
The Tabletop Cartridge Tape Subsystem (Tabletop CTS) is an 8mm cartridge
tape subsystem with its own housing and power supply. Accommodating a
single EXABYTE 8mm Cartridge Tape Subsystem (CTS), the Tabletop CTS
offers up to 2.5 gigabytes of tape storage with an EXB-8200 or EXB-8200SX
installed or up to 5 gigabytes of tape storage with an EXB-8500 installed.
The Tabletop CTS provides a high-performance, easy-to-implement solution
for high-capacity data storage. Because it comes with its own housing and
power supply, the implementor does not have to spend additional
development time designing an enclosure and obtaining agency approval.

2Installing the Tabletop CTS

2.5 Connecting the Tabletop CTS to the SCSI Bus
Two SCSI connectors are located on the back of the Tabletop CTS so that
multiple units can be connected in series for “daisy chained” configurations or
to accommodate one cable and an external terminator if the Tabletop CTS is
the last device on the SCSI bus.
To connect the Tabletop CTS to the SCSI bus, follow these steps:
1. Locate the two SCSI connectors on the back of the Tabletop CTS, as
shown in Figure 2-1 on page 2-3.
2. If the Tabletop CTS is the last device on the SCSI bus, plug a SCSI
cable into either one of the two connectors and the appropriate
single-ended or differential external terminator into the other connector.
or
If the Tabletop CTS will not terminate the SCSI bus (“daisy chain”
configuration), plug a SCSI cable into each connector. See Appendix B
for an illustration of a daisy chain configuration.
2.6 Connecting Power to the Tabletop CTS
The Tabletop CTS includes an internal power supply that is capable of
accepting 120 or 240 volts AC at 50 to 60 Hz. The Tabletop CTS has
autoranging voltage selection, so you do not need to change the voltage
setting.
A three-conductor AC power cord is shipped with the Tabletop CTS for
120-volt use in the United States and Canada. If you are planning to use an
input voltage other than 120 volts AC or if you will be using the Tabletop
CTS outside of the United States or Canada, you must supply your own
power cord. For information about the requirements for the power cord, refer
to Appendix A.
To connect power to the Tabletop CTS, follow these steps:
1. Make sure that the power switch on the back of the Tabletop CTS is off.
The switch is off when a 0 is visible on the left edge of the rocker switch.
Figure 2-2 shows the location of this switch.
2-4 510107
2Installing the Tabletop CTS

2. Connect the female end of the power cord to the power connector on the
back of the Tabletop CTS. To prevent possible power loss to the
Tabletop CTS, make sure that the power cord is fully connected to the
power connector.
3. Plug the male end of the power cord into the power source.

If the Tabletop CTS has been stored for less than six months, performing the
initial power-on involves the following steps:
1. Press the power switch on the back of the Tabletop CTS to the on
position. The switch is on when the 0 is hidden on the left edge of the
rocker switch. When power is turned on, the following activities occur
(see Figure 2-3):
The power-on LED on the front of the Tabletop CTS is illuminated.
The cooling fan mounted at the back of the Tabletop CTS begins to
rotate.
The CTS’s power-on self-test is performed. For a description of
what happens during this test, refer to the user’s manual for the
appropriate CTS.
2. If the Tabletop CTS does not power on as described in step 1, refer to
Section 2.8.

2Installing the Tabletop CTS

2.8 Failure to Power On
If the Tabletop CTS does not power on as described in Section 2.7, check the
following:
If the power-on indicator is not illuminated, check the following:
❏Is the power switch in the on position?
❏Is the power cord inserted correctly?
❏Is the fuse good? (See page 3-2.)
❏Is the power source providing power?
❏Is the Tabletop CTS connected to the SCSI bus? Is the SCSI bus
properly terminated?
If the power-on indicator is illuminated, check to see that the host
computer is turned on. If the host computer is turned on but the Tabletop
CTS still does not power on correctly, contact your vendor.
If the LEDs on the front of the CTS flash alternately or if the amber light
flashes, the CTS has failed its power-on self-test. The CTS door may also
open. Contact your vendor if any of these conditions occur.
If the LEDs on the front of the CTS remain lit after 65 seconds, ensure
that the SCSI bus is properly terminated.
If the fan on the back of the Tabletop CTS does not start rotating—or if it
stops rotating—and all other power-on operations complete normally, turn
off the Tabletop CTS and contact your vendor.
