Chapter 6 Maintaining the Router

Removing and Replacing a DC PEM

The AC Input Power and DC Output Power indicators on the power supplies

should light. If the indicators do not light, see the “Troubleshooting the AC Power

Supply Installation” section on page 6-22.

Removing and Replacing a DC PEM

This section contains the procedure to remove and replace a DC power supply

from the chassis. Before you begin this procedure, read the “Installation

Guidelines” section on page 6-14.

Figure 6-16 identifies the components of a DC power supply.
