Servers
Connecting Cables to NonStop Himalaya S-Series Servers
On NonStop Himalaya S-series servers, you can connect a tape drive CRU to a PMF
CRU, IOMF CRU, 6761 F-PIC on a 6760 adapter, or 6762 S-PIC on a 6760 adapter.
Connecting a SCSI Cable to the PMF CRU or IOMF CRU
Connect the SCSI cable to the PMF CRU or IOMF CRU as follows:
1. On NonStop Himalaya S7000, S7400, S70000, or S72000 PMF CRUs or IOMF
CRUs, make sure that a SCSI terminator is firmly installed in the SCSI port on the
left. (On all other PMF CRUs, the SCSI terminator is located inside the PMF CRU
and is not visible.) Removing the SCSI terminator from an unused port can hinder
tape drive performance and cause the SCSI interface to function improperly.
2. Plug the SCSI cable connector with the thumbscrews into the SCSI passthrough
terminator on the differential SCSI port on the PMF CRU or IOMF CRU residing in
either slot 50 or 55 in the system enclosure (see Figure 3-22 for PMF CRU cabling
and Figure 3-23 on page 3-38 for IOMF CRU cabling).
3. Tighten the thumbscrews on the SCSI cable connector by hand or use a small
slotted screwdriver.
4. Refer to the Himalaya S-Series Hardware Installation Guide for cable routing
instructions for the PMF CRU or IOMF CRU.
5. Use SCF to add the modular tape subsystem to your configuration. See
Configuring the Modular Tape Subsystem Online Using SCF on page 2-25.
6. Bring each tape module online. See Bringing the Tape Drives Online After
Installation on page 3-39.
7. Reinstall the rear bezel door for each tape drive module, making sure that any AC
power cords or cables are routed properly through the door cutouts and into the
extrusion channels on the sides of the module.
