DC-Input Power Entry Module
The DC-input PEM (Figure1-9) 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 modul e
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 p ower. Do
not mix AC-input power supplies and DC-input PEMs.
