Tape Drive Configurations
PMF CRU or IOMF CRU (NonStop Himalaya S-Series
Servers)
A SCSI SAC within a PMF CRU or IOMF CRU supports one tape drive CRU (see
Figure 3-7). For a module containing two drives, you must attach the tape drives to
separate CRUs. The PMF CRU or IOMF CRU uses SCSI cable for attachment to the
tape drive CRU.
6760 Adapter With 6761 F-PIC (NonStop Himalaya S-Series
Servers)
A SAC on a 6761 F-PIC within a 6760 device adapter can support one tape drive CRU.
Fiber-optic cable attaches the F-PIC to the drive CRU (see Figure 3-8). The 6761
F-PIC requires a back-end board (BEB) to translate fiber-optic signals into SCSI data.
You must install the BEB by plugging it into the SCSI port and securing the wing nut
(see Installing the BEB (Fiber-Optic Cables Only) on page 3-25).
