Chapter 6 Maintaining the Router

Removing and Replacing AC and DC Power Subsystem Components

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

Installation Guidelines

The Cisco 12006 and Cisco 12406 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. Make sure you have the tools and the replacement power supply ready before beginning the removal and installation procedure.

Power Supply and PDU Compatibility

Cisco 12006 and Cisco 12406 series routers are available with either an AC or DC power supply system. The two types of power supplies for these systems are:

•Original power supplies (rated at 1400 watts) that shipped with earlier systems

•Enhanced capacity power supplies (rated at 1900 watts) that ship with current systems and upgrade kits

Removal and replacement procedures are the same for either type of power supply, but because of their power capacity and physical differences, you cannot mix different types of power supplies in the chassis.
