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.

Each Lenovo Storage V series 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, the Ethernet port number starts at 3.
Note: The Ethernet cables are connected in pairs. Both canisters must have the same number of cables connected.

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.
Example of a Lenovo Storage V3700 V2 XP system with a 2-port 25 Gbps Ethernet host interface adapter shows the Ethernet ports on a node canister, as seen from the back of a Lenovo Storage V3700 V2 XP system. This example shows a 25 Gbps Ethernet (RoCE) adapter.
