Installing Power Boards in Cisco Ethernet Switch Network Modules

78-14282-02

Tools and Equipment Needed

You need the following tools and equipment to remove and install Compact Flash memory cards:

• ESD-preventive wrist strap

• Antistatic bag or mat

• Number 2 Phillips screwdriver or flat-blade screwdriver

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.
