Onboard Ethernet ports
In the control enclosure, Ethernet port 1 of each node canister is connected to an enabled port on your Ethernet switch or router. Ethernet
port 1 is used for accessing the management GUI, for accessing the service assistant GUI for the node canister, and for iSCSI host
attachment. You can also attach an Ethernet cable from Ethernet port 2 on the node to canister your Ethernet network. Port 2 can be used
for the management GUI and for iSCSI host attachment. Ethernet ports 3 and 4 are for iSCSI attachment only.
The ports on the upper node canister (canister 1) are
numbered from right to left.
The ports on the lower node canister (canister 2) are
numbered from left to right.
Use the following table to record the connections to the onboard Ethernet ports of each node canister in the control enclosure.

Ethernet networking adapters
Each node canister supports 2-port 25 Gbps internet Wide-area RDMA Protocol (iWARP) or RDMA over Converged Ethernet (RoCE) Ethernet
adapters. Install the adapters according to the following guidelines.
• iWARP and RoCE Ethernet adapters cannot be mixed within a node canister.
• Fibre Channel adapters are installed before Ethernet adapters, beginning with slot 1, then slot 2, and slot 3.
• Ethernet adapters are installed beginning with the first available slot.
• To connect to expansion enclosures, you must order a 4-port 12 Gbps SAS adapter that is installed in slot 3. However, only ports 1 and 3
are used to establish a SAS connection
Use the following table to record information about the Ethernet ports that are used for node-node RDMA communications.
