DC-Input Power Entry Module

The DC-input PEM (Figure 1-9) is a removable power module that installs in one of the bottom two bays on the front of the chassis (see Figure 1-1). These power modules support the OIR feature and are hot-swappable.

Note When operating your router on a single power module, the second power module bay must have a blank filler (MAS-GSR-PWRBLANK=) installed to ensure EMI compliance.

Caution The Cisco XR 12406 Router is configured for either AC power or DC power. Do not mix AC-input power supplies and DC-input PEMs.
