IBM 71455DU manual Connecting the cables, Rear view, Front view

Connecting the cables

You must turn off the server (see “Server power features” on page 12) before connecting any cables to or disconnecting any cables from the server.

See the documentation that comes with optional devices for additional cabling instructions. It might be easier for you to route cables before you install certain options.

Cable identifiers are printed on the cables that come with the server and options. Use these identifiers to connect the cables to the correct connectors.

For details about the location and function of the input and output connectors, see “Server controls, connectors, LEDs, and power” on page 9.

Two optional SMP Expansion cable kits are available to interconnect the SMP

Expansion Ports of two or more servers:

v2.3 m XpandOnDemand™ Scalability cable kit (comes with one 2.3-m (7.6-foot) SMP Expansion cable)

v2.9 m XpandOnDemand Scalability cable kit (comes with one 2.9-m (9.5-foot) SMP Expansion cable)

The following illustrations show the locations of the input and output connectors on the server. Detailed cabling instructions are in the Rack Installation Instructions that come with the server.
