Cabling a single-interconnect configuration

Procedures for cabling theThinkAgile CP single-interconnect switch configuration.

Complete these procedures to cable a single-interconnect configuration.

Hardware management network connections

Connect the following ports to the management switch:

Note:

If not using the Lenovo ThinkSystem NE0152T RackSwitch as the management switch, you may require different cables for the management network connections.

Compute block connections (single-interconnect configuration)

The compute block consists of an enclosure with up to four compute nodes, which are numbered as follows:

Connect the compute nodes according to the populated compute node location and corresponding port mapping. The cables to be used are clearly labeled; make sure that you use the correct cables.

You need two SFP+ Direct Attach Cables (DACs) for each populated compute node.

The compute block port mapping is as follows:

Front compute node location

Back network port mapping

Compute node 2, port 2 (C.2.2)

Interconnect, port 4

Note:

You only need to cable the number of compute nodes that are installed in the compute enclosure.

Storage block connections (single-interconnect configuration)

Connect the storage controllers according to the populated controller location and corresponding port mapping. The cables to be used are clearly labeled; make sure that you use the correct cables.

You need eight Category 6 patch cables and eight SFP+ transceivers. Attach a single SFP+ transceiver to each patch cable.

The storage block port mapping is as follows:

Front storage controller location

Back network port mapping
