One Power Supply Module has already been installed in the switch. Operate as the following steps if
you need to replace the Power Supply Module.
Removing the Power Supply Module
■
1. Wear an ESD-preventive wrist strap, and make sure that it has good skin contact and is well
grounded.
2. Remove the power cord from the power module and the external power supply system.
3. Use a Phillips screwdriver to loosen the captive screws at both sides of the power supply module
until all spring pressure is released.
4. Pull the handle by one hand towards you along the guide rails, and hold the bottom of the module
by the other hand, until it completely comes out of the switch chassis.
5. In order to better protect the removed power supply module, it is recommended to package it by
an antistatic bag.
