Power Supply and Power Distribution Unit Compatibility

Cisco 12010, Cisco 12410, and Cisco 12810 series routers are available with either an AC or DC power supply system. There are currently two types of power supplies in use for these systems:

Original power supplies (rated at 2400 watts)—Shipped with older systems

Enhanced capacity power supplies (rated at 2800 watts)—Ships currently

The removal and replacement procedures are the same for either type of power supply. Because of their capacity and physical differences, you cannot mix different types of power supplies in the chassis. Power supplies are also referred to as Power Entry Modules (PEMs).

Enhanced capacity 2800 W PEMs also require upgrades to new Power Distribution Units (PDUs). You cannot install enhanced capacity PEMs using the original PDUs. If you plan to replace original PEMs with enhanced PEMs, you must replace both the PEMs and the PDUs.

Before you attempt to install or replace them, be sure you know the power supplies and associated PDUs your system has (Table 1).

Prerequisites and Preparation

Before you perform any of the procedures in this guide, be sure that you:

Read the safety and ESD-prevention guidelines in this section.

Ensure that you have all of the necessary tools and equipment before beginning the installation (see the "Installation Guidelines" section).

Have access to the following documents during the installation:

Regulatory Compliance and Safety Information for Cisco 12000 Series Routers publication that shipped with the router (PN 78-4347-xx)

Cisco 12010, Cisco 12410, and Cisco 12810 Router Installation and Configuration Guide

For additional information about obtaining documentation see the "Obtaining Documentation" section.

Safety Guidelines

Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.

Safety Warnings

Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement. The following warning is an example of a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard.


Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanies this device.


Preventing Electrostatic Discharge Damage

Many router components can be damaged by static electricity. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes good skin contact.


Note You should periodically check the resistance value of the ESD-preventive strap. The measurement should be between 1 and 10 megohms.


Before performing the procedures in this guide, attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface as shown in Figure 1.

Figure 1 Connecting an ESD-Preventive Wrist Strap to the Chassis

Installation Guidelines

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. You can 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 two 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.


Caution You cannot mix power supply types within the chassis. If you are replacing a 2400 W power supply from an older system with a newer 2800 W power supply, you must replace both power supplies and the PDUs (see Table 1). You must shut down the router to perform the upgrade. Be sure to notify the appropriate personnel that all routing traffic stops while the upgrade takes place.


Caution Cisco 12010, Cisco 12410, and Cisco 12810 series routers configured with non-enhanced fabric and a single power supply and with more than five Engine5 line-cards may fail to boot during the start-up procedures. To safeguard against this possibility ensure that the chassis is configured with two power supplies or configured with the enhanced fabric.

Required Tools and Equipment

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

FCC Class A Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case you are required to correct the interference at your own expense.

Modifying the equipment without Cisco authorization may result in the equipment no longer complying with FCC requirements for Class A digital devices. In that event, your right to use the equipment may be limited by FCC regulation and you may be required to correct any interference to radio or television communication at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

Turn the television or radio antenna until the interference stops.

Move the equipment to one side or the other of the television or radio.

Move the equipment farther away from the television or radio.

Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
