Replacing a Fabric Board

The Fabric Interconnect contains 24 InfiniBand ports that connect to client servers. Each port is a double data rate (DDR) link to the server and operates at 20 Gbps, but will auto negotiate down to Single Data Rate (SDR) based on the devices that the Fabric Interconnect is connected to. Ports are numbered left to right starting at the bottom left-hand corner.

This section documents how to replace the InfiniBand Fabric Board. For this procedure, you will need to power off the Fabric Interconnect.

To perform this procedure, you will need the following tools:

• #2 Phillips (cross-head) screwdriver

• an ESD wrist strap
