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:
Do not remove or install modules without using appropriate anti-static guard measures. The SCE 2000
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.
Never install an AC power module and a DC power module in the same chassis.
