Desktop Units
SCSI Cables (Desktop/CSL)
The 9840 Tape Drive/CSL 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 (refer to Figure 3-7) to indicate the electrical configuration
for that port.
Use the instructions below to install the SCSI cables to the desktop 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.
