Power Supply and Power Shelf Compatibility
Cisco 12016 series routers are available with either an AC or a DC power supply
system. Two types of power supplies are available for these systems:
•
Original power supplies (rated at 2000 W)—Shipped with original systems
•
Upgraded replacement power supplies (rated at 2500 W AC or
2400 W DC)—Ships currently
Removal and replacement procedures are the same for either type of power
supply, but because of their capacity and physical differences, you cannot mix
different types of power supplies within the same power shelf.
Caution
Newer power supplies (AC and DC) require upgraded power shelves. You cannot
install a new power supply using the original power shelf. If you are replacing an
older power supply with a new unit, you must replace
all
of the power supplies
and
the power shelf.
Before you attempt to install or replace them, be sure you know the power
supplies and associated power shelf your system has (
Table 7-1
).
