3.13 Patch Panel Connections
Each drive FRU contains one 68-pin SCSI socket and one 50 pin
SCSI socket or ports via the BEB Patch Panel. When the 5155/5159
drive FRU is attached to an MFC, the 50-pin SCSI port is used for
the copper cable connection and the 68-pin SCSI port is capped with
a SCSI terminator.
When the 5155/5159 drive FRU is attached to a 3216 controller, one
port is used for the BEB and the other port is either capped with a
SCSI terminator or linked by a daisy-chained cable to the other drive
FRU in a module. (A SCSI terminator completes the SCSI chain on
the second drive FRU.)
Note: Removing the SCSI terminator from an unused
port can prevent operation.
Figure 3-8 shows the location of the 5155/5159 tape drive FRUs in
the 9710 Automated Cartridge Subsystem. The BEB, cabling, and
SCSI terminator are not shown.
