Replacing the Power Supply Modules

This section describes how to replace the Power Supply module. It describes replacement of the Power Supply module #1 (on left side of chassis), but it also applies to the Power Supply module #2. In addition, it describes replacement of the AC Power Supply module, but it also applies to the DC Power Supply module.

The Power Supply module is hot-swappable and thus, can be replaced without powering down the device (i.e., disconnecting the power source from the second Power Supply module).

● Before extracting the Power Supply module, disconnect the power cord from the module.
● Before extracting the Power Supply module (after you have disconnected the power cord), wait at least three seconds for the capacitors to discharge.

Avertissements: Avant d’extraire un module de Bloc d’alimentation du châssis (après avoir débranché le cordon électrique), patientez au moins 3 secondes que les capacités se déchargent.
