I/O Multifunction (IOMF) CRU

You can also attach a tape drive CRU to the SCSI port on an IOMF CRU.

Figure 1-7 shows a NonStop Himalaya S-series I/O enclosure with two IOMF CRUs.

SCSI Cable (PMF CRU, IOMF CRU, or 6760 Adapter)

Copper SCSI cable is used to connect a tape drive CRU to a PMF CRU, IOMF CRU,

or an 6762 S-PIC in 6760 adapter.

On NonStop Himalaya S7000, S7400, S70000, or S72000 PMF CRUs or IOMF CRUs,

one end of the cable has a connector with latch-clip flanges that connects to the

uncapped SCSI port at the rear of the tape drive CRU. The other end of the cable has

a connector with thumbscrews that connects to the SCSI passthrough terminator

that is preinstalled on the PMF CRU or IOMF CRU differential SCSI port.

On all other PMF CRUs for NonStop Himalaya S-series servers, the SCSI terminator is

located inside the PMF CRU and is not visible.

The SCSI cable comes in a separate box when the tape subsystem is delivered. SCSI

cable lengths can range from 10 feet (3 meters) to 75 feet (23 meters). Appendix A,

Part Numbers, lists part numbers.
