Installation Guidelines

OL-11496-01
This section contains removal and replacement procedures for the AC and DC
power systems used with the Cisco 12010, Cisco 12410, and Cisco 12810 series
routers. If you ordered an upgrade kit, you can use these same procedures to
upgrade all of the power system components.
The illustrations in this procedure represent both original and upgraded power
supplies and PDUs shipping with the Cisco 12010, Cisco 12410, and Cisco 12810
series routers. Depending on your system, these components may not look exactly
like those in your chassis, but the removal and replacement procedures are
essentially the same. Multiple illustrations are presented to represent original and
new models where appropriate.
The following tools and equipment are required to remove and install power
equipment:
Number 1 Phillips screwdriver
3/16-inch flat-blade screwdriver
An ESD-preventive wrist strap
The Cisco 12010, Cisco 12410, and Cisco 12810 series routers support online
insertion and removal (OIR). If you are replacing a redundant power supply, you
can remove and install the power supply while the system remains powered on
without causing an electrical hazard or damage to the system. This feature enables
you replace a power supply while the system maintains all routing information
and ensures session preservation.
However, to maintain operational redundancy, proper cooling, and meet EMI
compliance standards, you must have both working power supplies installed.
When you remove a failed power supply with the router in operation, perform the
replacement as quickly as possible. Before you begin the removal and installation
procedure, make sure you have the tools and the replacement power supply ready.
