SCSI Cables (Rack-mount Tray)
The 9840 Tape Drive connects to a SCSI bus and supports only the differential
alternative.
Note: Term power is not supplied by the 9840 Tape Drive, it must be supplied
by the host bus adapter card.
All host systems should have either the SCSI ports labeled or the international
symbols displayed (Figure 3-9) to indicate the electrical configuration for that
port.
Use the instructions below to install SCSI cables for a drive or CSL:
CAUTION:
Maximum cable length. The maximum cable length for the differential
alternative is 25 m (82 ft). Make sure that the total cable length (including
all daisy-chain cables) from the host to the last device does not exceed
the maximum length.

1. Mark each cable with the device address; it is needed later to configure the drive/CSL.
2. Route the SCSI cable(s) from the host under the floor to the rack.
Note: Do not attach either end of the cable(s) at this time.
3. Route the SCSI cable(s) for the first tray through the floor tile cutout then through the
cable cutout in the floor of the rack, and up to the rear of the CSL or drive tray.
