Rack and Offset Physical Location

In NonStop S-series systems, group, module, and slot (GMS) notation identifies the

physical location of a component. However, GMS notation in Integrity NonStop

NS-series systems is the logical location of particular components rather than the

physical location.

Rack and Offset Physical Location

Rack name and rack offset identify the physical location of components in an Integrity

NonStop NS-series system. The rack name is located on an external label affixed to

the rack, which includes the system name plus a 2-digit rack number.

Rack offset is labeled on the rails in each side of the rack. These rails are measured

vertically in units called U, with one U measuring 1.75 inches (44 millimeters). The rack

is 42U high with 1U located at the bottom and 42U at the top. The rack offset is the

lowest number on the rack that the component occupies.

This example shows the location of slice A in rack 1 with an offset of 3U and slice B

with an offset of 8U:

Slice Group-Module-Slot Numbering

•

Processor group: 400-403 relates to processor complex of 0-3

Example: group 403 = processor complex 3

•

Module: 1-3 relates to the CPU slice ID of A-C

Example: module 2 = slice B

•

Slot: 71-78 relates to location of the slice optics adapter

Example: Slot 72 = optics adapter in slot 72

•

Port: J0-J7 or K0-K7 relates to the two optic ports in a specific slot
