the system by hosts on the network. If more than one control enclosure is present 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.
Connecting Ethernet cables to 1 Gbps iSCSI 4-port host interface adapters
If you installed an optional 1 Gbps iSCSI 4-port host interface adapter, you can use Ethernet cables to
connect the system to your Ethernet SAN.
About this task
Each system has two Ethernet ports, port 1 and port 2, that are built into the canister. When a 4-port
Ethernet host interface adapter is installed, the port number starts at 3.
Note: The Ethernet cables are connected in pairs. Both canisters must have the same number of cables
connected.
Procedure
To install the cables, complete the following steps.
1. Identify the correct pair of Ethernet cables for the Ethernet ports labeled 3 in the left canister and the
right canister.
2. Connect the appropriate cable to each port.
3. For each additional pair of Ethernet ports in the right and left canisters, identify the correct pair of
cables and connect them.
Results

Connecting Ethernet cables to 25 Gbps iSCSI 2-port host interface adapters
If you installed an optional 25 Gbps iSCSI 2-port host interface adapter, you can use Ethernet cables to
connect the system to your network.
About this task
Each system has two onboard Ethernet ports, port 1 and port 2. When an optional 2-port 25 Gbps
Ethernet host interface adapter (RoCE or iWARP) is installed, two optical Ethernet ports are added to each
canister. These ports are numbered 3 and 4.
