AC Power Entry Module
OL-11636-01
The Cisco 12404 router chassis supports two 1100 W hot swappable PEMs. Each
unit is capable of delivering up to 1100 W at –54.5 VDC. The
Cisco 12404 Internet router PEMs are hot swappable and the router must be
populated with 2 PEMs to meet EMI standards.
Do not mix PEM types in the Cisco 12404 Internet router. In multiple PEM
system configurations, all PEMs must be of the same type; either all AC PEM, or
all DC PDUs and PEMs.
A hardwired DC power source, power cable is required from the site DC power
source to the DC PDU on the chassis. The DC power cable leads are 6 American
Wiring Gauge (AWG) high strand count wire.
For detailed handling and replacement instructions for Cisco 12404 router PEMs,
see Appendix A or the appropriate configuration note that accompanies each
AC PEM or DC PEM and PDU shipped from the factory as an FRU.
The AC PEM is a modular unit which measures:
6.60 inches (16.76 cm) deep by 14.30 inches (36.32 cm) wide by 3.50 inches
(8.89 cm) high
Weight: 11.0 lbs (5.0 kg)
The Cisco 12404 router is configured to the customer specifications from the
factory (Figure 1-12). If AC PEM is requested, two AC PEM are shipped. Each
AC PEM should be connected to a separate AC power source.
