Replacing an Indicator Board's Adapter

Replacing an Indicator Board's Adapter

This section explains how to replace an indicator board's adapter.

Prerequisites

  • A replacement adapter is ready.
  • The adapter that you want to replace has been located.

Precaution

Remove and insert the adapter with even force. Excessive force may damage the appearance or connectors of the adapter.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Label
  • Phillips screwdriver
  • Diagonal plier

Procedure

  1. Wear an ESD wrist strap. Open the front cabinet door.
  2. Remove the adapter to be replaced.
    1. Slightly pull out part of the adapter tray. Stop pulling when you can put your hands into the tray, as shown in Figure 13-3.

      Do not pull out the adapter tray too much to avoid damaging the power cable of the adapter. One end of the power cable connects to the adapter of the indicator board and the other end connects to the PDU at the back of the cabinet.

      NOTE:

      The adapter is located between 17 U and 18 U of the cabinet.
