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
Caution -
When tightening screws, make sure to tighten them to lightly snug. Do not
overtighten screws or they can break.
Caution -
When replacing the Fabric Board: - wear an ESD wrist strap - When the hardware is
out of its shipping package or not in the Fabric Interconnect chassis, make sure you place it in
an ESD safe bag or on a grounded work surface such as a rubberized work mat.
