This section explains how to wire the out-of-band management (IPMI) port, 100 Gbps ports, and power on Supermicro 1114S nodes.

This platform uses a split networking configuration in which different NICs handle back-end and front-end traffic. You can connect the front-end and back-end NICs to the same switch or to different switches.

Step 1: Connecting the Out-of-Band Management (IPMI) Port

The dedicated out-of-band management port allows functionality such as remote display, control, and power. The port uses the Intelligent Platform Management Interface (IPMI) protocol. Connect the IPMI port first on the back of your node (above the USB ports).

To configure the IPMI port, you must use the IPMI Management Utility installed on the motherboard. For more information, see Supermicro BMC User Guide X12. The default IPMI username is ADMIN and the default password is printed on a label on the node’s motherboard.

Step 2: Connecting the 100 Gbps Ports

After you connect the IPMI port, connect your front-end and back-end 100 Gbps ports (compatible with QSFP28 and QSFP56). There are four 100 Gbps ports on the back of your node. To maximize redundancy, split interfaces across subnets by connecting each port to a different switch.

Bottom row 2 (eth5), 1 (eth4) Back end Communication between nodes

Step 3: Connecting the Power

After you connect your 100 Gbps ports, connect power to the node. There are two power sockets on the back of your node. To maximize redundancy, connect each PSU to a separate power supply or power distribution unit (PDU).
