Connecting Ethernet cables to the node canisters

To provide system management connectivity for your system, you must connect Ethernet cables to at least Ethernet port 1 of each node canister in the control enclosure.

To install the Ethernet cables, complete the following steps.

1. Locate the onboard Ethernet ports of each node canister in the control enclosure. Figure 1 shows the location of the onboard Ethernet ports.

   

   •  1  Power supply units
   •  2  Adapter cages
   •  3  Fixed use (compression cards)
   •  4  Node canisters
   •  5  1 GbE management ports
   •  6  Technician port

   Connect Ethernet port 1 of each node canister in the control enclosure to the IP network that provides connection to the system management interfaces, as shown in the Table 2 that a customer fills and provide to the IBM SSR. Where more than one control enclosure is present in the system, ensure that the port 1 of every node canister is connected to the same network to provide management access if the configuration node fails.

2. Optionally, connect Ethernet port 2 of each node canister in the system to a second IP network that will provide redundant connection to the system management interfaces, if the customer indicates this connection on the onboard Ethernet connections planning worksheets.

   It is possible that the Ethernet adapters in the adapter cages of each node canister. In that case, look at the Ethernet adapter port connections table of the planning worksheets that the customer fills and provide to the IBM SSR to see whether the customer wants the SSR to make any such connections. The SSR needs to make any connection from Ethernet adapter ports that might be used for node-to-node communications.

3. Connect the Ethernet cables to any Ethernet adapter ports that the customer documented on the network connections worksheet, if the customer indicated on the worksheet that they wanted the IBM SSR to connect those cables.
