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:

• Interconnect port 47 using a SFP+ Direct Attach Cable (DAC)

• Compute block port (C.M.) using a RJ45 patch cable

• Upper storage block port (S.U.M.) using a RJ45 patch cable

• Lower storage block port (S.L.M.) using a RJ45 patch cable

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	Network interconnect port
Top left	Compute node 3, port 1 (C.3.1)	Interconnect, port 5
	Compute node 3, port 2 (C.3.2)	Interconnect, port 6
Top right	Compute node 4, port 1 (C.4.1)	Interconnect, port 7
	Compute node 4, port 2 (C.4.2)	Interconnect, port 8
Bottom left	Compute node 1, port 1 (C.1.1)	Interconnect, port 1
	Compute node 1, port 2 (C.1.2)	Interconnect, port 2
Bottom right	Compute node 2, port 1 (C.2.1)	Interconnect, port 3
	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	Network interconnect port
Upper	Upper storage controller, port 1 (S.U.1)	Interconnect, port 17
	Upper storage controller, port 2 (S.U.2)	Interconnect, port 20
	Upper storage controller, port 3 (S.U.3)	Interconnect, port 21
	Upper storage controller, port 4 (S.U.4)	Interconnect, port 24
Lower	Lower storage controller, port 1 (S.L.1)	Interconnect, port 25
	Lower storage controller, port 2 (S.L.2)	Interconnect, port 28
	Lower storage controller, port 3 (S.L.3)	Interconnect, port 29
	Lower storage controller, port 4 (S.L.4)	Interconnect, port 32
