Step 2 Remove the thumbscrews on either side of the power board port. Put these in a safe place as they will be
replaced once the power board is installed.
Step 3 Guide the external connector through the power board port opening on the card faceplate.
Step 4 Insert the connector on the power board into the connector on the network module. See Figure 2 for
16-port Ethernet switch network modules and Figure 3 for 36-port Ethernet switch network modules.
Note Be sure to press firmly on the power board until the board seats onto the connector.
Step 5 Insert the screws from the board installation kit through the power board into the standoffs on the
network module.
Step 6 Replace the thumbscrews on either side of the power board port. Make sure the thumbscrews are
