DC-Input Power Entry Module
The DC-input PEM 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 Cisco 12006 and Cisco 12406 routers are configured for either AC power or DC
power. Do not mix AC-input power supplies and DC-input PEMs.
