Removing and Replacing a Power Supply Unit

The procedures for removing and replacing the AC-input or DC-input power supply are explained in the following sections:

Powering Down the Power Supply Unit and Disconnecting Input Power (on page 4-15)

Removing the Power Supply Unit (on page 4-16)

Replacing the Power Supply Unit (on page 4-17)

Reconnecting the Power (on page 4-17)

ESD Warning Do not remove or install modules without using appropriate anti-static guard measures. The SCE 1000 includes an anti-static wrist strap in the accessory kit. Attach the copper tape strap to an unpainted metal surface on the chassis. You may leave the strap connected to the chassis when your have finished.
