Connecting Ethernet cables to the node canisters

On systems, the control enclosure has several Ethernet ports present or optionally present on the rear of each node canister. Ports 1 and 2 provide access to system management facilities. Ports 1, 2 and 3 on the rear of each canister can also provide iSCSI connectivity and IP replication.

To install the Ethernet cables, complete the following steps.

1. Connect Ethernet port 1 of each node canister in the system to the IP network that will provide connection to the system management interfaces, as shown in Figure 1.
   This port can also be used for iSCSI connectivity to the system by hosts on the network. Where more than one control enclosure is present in the system, ensure port 1 of every node canister is connected to the same network to provide 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, as shown by the lighter cable connection in Figure 1.
   This port can also be used for iSCSI connectivity to the system by hosts on the network. If there is more than one control enclosure in the system, ensure that port 2 of every node canister is connected to the same network to provide access if the configuration node fails.
3. Optionally, connect Ethernet port 3 of both node canisters in a system to the networks that will provide extra iSCSI connectivity to the system.
   Note: Do not connect the Ethernet technician port (labeled T) to a network switch. The technician port must only be directly connected to a personal computer when initializing a system or servicing a node.
