This topic provides general information about the Sun Grid Rack System cable harnesses.

The Sun Grid Rack System is shipped with all required cables already installed, routed, and connected in cable harnesses. A cable harness is an assembly of pre-formed cables integrated into the rack as a single unit. Each cable is a single integral component of the harness with RJ-45 connectors and a unique identification label at each end.

The Sun Grid Rack System imay include three cable harnesses:

• Ethernet data harness (yellow)

  Connects each compute node to the 48-port data fabric switch or to one of the 24-port data fabric switches. If the two 24-port switches are used to create a single fabric, the cables are interleaved between the two switches.

  Connects the management node to the data fabric switch.

• Ethernet management harness (orange)

  Connects each compute node to the management fabric switch.

  Connects the management node to the management fabric switch.

• Serial data harness (white)

  Connects the serial port on each node to the terminal server.

Serial cables used for terminal server connections are RJ-45 to RJ-45 rollover cables (8-core, Cat 5 type Ethernet). Network cables used for network switch connections are RJ-45 to RJ-45 straight cables (8-core, Cat 5/5e type Ethernet).

The harnesses are secured vertically to the rack with cable ties; the Ethernet data harness is secured closest to the front of the rack. The cables are labeled to make it easy to reconnect them if any come loose during shipping, or if components are subsequently replaced. The labels match the information in the port to cable connection mapping table for each harness.

If your configuration includes two Cisco 24P switches, the switches are connected with a Cisco StackWise cable. See the documentation included with the switch for more information.
