IOMF 2 CRU

The Integrity NonStop NS16000 system is compatible with most disks and ServerNet

adapters contained in currently installed NonStop S-series I/O enclosures equipped

with IOMF 2 CRUs. I/O multifunction 2 (IOMF 2) CRUs, each equipped with an MMF

PIC, are required for connecting NonStop S-series I/O enclosures to Integrity NonStop

NS16000 systems.

To retain disk drives and adapters currently installed in NonStop S-series system

enclosures, you can convert these enclosures to NonStop S-series I/O enclosures,

replacing the two PMF CRUs in each enclosure with IOMF 2 CRUs. See the

conversion instructions in the Hardware Service and Maintenance Publications

category of the Support and Service Library of NTL. Refer to Support and Service

Library on page C-1. For information on the IOMF 2 CRUs, see the NonStop S-Series

Planning and Configuration Guide.

NonStop S-Series Disk Drives and ServerNet Adapters

Disk drives and ServerNet adapters (except SEB, MSEB CRUs, ServerNet/FX and

ServerNet/FX 2 adapters) installed in NonStop S-series I/O enclosures equipped with

IOMF 2 CRUs, as well as devices that are downstream of the enclosures, are

compatible with the Integrity NonStop NS16000 hardware, as long as the NonStop

S-series I/O enclosure is properly connected to the p-switches. For information on the

NonStop S-series disk drives and ServerNet adapters, see the NonStop S-Series

Planning and Configuration Guide.

NonStop S-Series I/O Enclosure Group Numbers

Assignment of the group number of each NonStop S-series I/O enclosure depends on

the cable connection to the p-switch PIC by slot and port. For PIC slot and connector

locations, see Processor Switch Group-Module-Slot Numbering

on page 5-34.

The cables from the two IOMF 2 CRUs must connect to PICs residing in the same slot

number in both the X and Y p-switch and to the same port number on each PIC. For

example, the preceding illustration shows the cables from the IOMF 2 CRUS in the

NonStop S-series server connected to port 1 of the PICs in slot 4 of the X and Y

p-switch, assigning the group number of 11.

Caution. Do not attempt to use NonStop S-series SEB or MSEB CRUs in NonStop S-series

I/O enclosures connected to Integrity NonStop NS16000 systems. System failure will result.
