Adding an Optional Power Board
An optional power board can be used if the Ethernet switch network module requires external -48V power for IP telephones. Installation and configuration of the external power suppy system is described in the Cisco External Power Supply for Cisco Ethernet Switch Network Modules Installation Guide. Use the Cisco Network Modules Hardware Installation Guide and platform hardware installation guide for more information.
Follow this procedure to install power boards:
Step 1 Use a Philips screwdriver to remove the cover on the external power board port, as shown in Figure 1.

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 tightened firmly.
Warning Do not connect the external power supply cable to the power connector on the front of the network module until the network module has been inserted into the router chassis. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Step 7 After installing the network module into the chassis, connect the power cable to the power module connector on the front of the network module. See the Cisco External Power Supply for Cisco Ethernet Switch Network Modules Installation Guide for more information.
