This appendix contains the following topics:
Note:
The eighth-, quarter-, and half-rack X4-2 and newer machines are pre-cabled with a complete set (equivalent in number to a full rack) of InfiniBand (92), Ethernet (42), and power cables. All the cables are connected to the appropriate switches and routed to the correct rack-unit location. The unconnected ends of the cables are tied off to lacer bars. At a later time, when the machine is upgraded to a larger rack, the filler panels and lacer bars are removed, the X4-2 and newer servers are installed with rack rails and cable-management arms, and the cables (power, InfiniBand, and Ethernet) are connected to the newly installed compute nodes.
The following abbreviations are used in the tables:
| Abbreviation | Description |
|---|---|
|
Rn |
Rack n, where n is the number of the rack, such as R1. |
|
Un |
Unit height in rack, where n is the number, such as U20. |
|
Pn |
InfiniBand port n, where n is port number, such as P8A. |
