Chapter 1 Cisco 12010, Cisco 12410, and Cisco 12810 Series Router Overview
Physical and Functional Description of Router
AC and DC Power Subsystems
A router ships as either an AC or DC powered system. Source power connects to
power distribution units (PDUs) on the back of the chassis which route power to
the power supplies, also referred to as power entry modules (PEMs).
Caution
To ensure that the chassis configuration complies with the required power
budgets, use the on-line power calculator. Failure to properly verify the
configuration may result in an unpredictable state if one of the power units fails.
Contact your local sales representative for assistance.
AC Power Entry Modules
An AC powered router consists of two (2400 W or 2800 W) AC PDUs and
AC PEMs. AC power to the router is provided through power cords connected
from AC power outlets to the PDUs on the chassis rear panel as shown in
Figure 1-3
AC PDU Connection—2400 W
Each AC PEM converts 200 to 240 VAC into -48 VDC, which is distributed
through the chassis backplane to all cards, RPs, and the blower module.
