Replacing a DC Power Supply

We recommend using a Model 10933 power supply, connected to a +24 V power source.

In a redundant power configuration, you can replace one DC power supply without powering down the router.

Before you start, have the following items on hand:

• #1 Phillips screwdriver
• Torque screwdriver and wrench or torque driver with attachments for tightening screws and nuts
• Thermal protective gloves (required for removing a power supply)

Warning

Be sure to disconnect all power cables before you disconnect the chassis ground wire.

When replacing a power supply unit, be sure to observe all of the safety recommendations in Installing Power Supply Units and Connecting Power.
