Cisco 10000 ESR Blower Module Installation
This publication contains instructions for installing the Blower Module in the Cisco 10000 Edge Services Router (ESR). If you are not familiar with the Cisco 10000 router, see the Cisco 10000 ESR System Description, and the Cisco 10000 ESR Hardware Installation Guide for additional information.
The following sections are included in this configuration guide:
The Cisco 10000 ESR uses a blower module located at the top of the router (Figure 1) to supply cooling air to the chassis.
Figure 1 Blower Module
Four internal fans in the blower module:
•Draw cooling air into the front of the chassis and directs it across the internal components to maintain an acceptable operating temperature.
•The air is then exhausted through openings in the rear of the chassis.
Prerequisites and Preparation
Before you perform any of the procedures in this guide, Cisco recommends that you:
•Read the safety guidelines in the next section and review the electrical safety and ESD-prevention guidelines in the Cisco 10000 ESR Hardware Installation Guide.
•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 (shipped with your Cisco 10000 system) during the installation:
–Cisco 10000 ESR System Description
–Cisco 10000 ESR Hardware Installation Guide
–Cisco 10000 ESR Troubleshooting Guide
–Cisco 10000 ESR Software Configuration Guide
Before you begin the installation or replacement procedure, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. Before you install, configure, or perform maintenance on the router, you should also review the safety warnings listed in the Cisco 10000 ESR Hardware Installation Guide.
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 accompanied this device.
Note If you need translations of the safety warning, see the Cisco 10000 ESR Hardware Installation Guide.
The Cisco 10000 system is hot-swappable, which means you can remove and replace a defective blower module while the system is operating. It is not necessary to notify the software or reset the system power. This feature lets you replace the blower module while the system maintains all routing information and ensures session preservation.
Caution Although the blower module supports hot-swapping and can be replaced without interruption to system operation, the system should not operate without the blower module for more than a few minutes to prevent overheating.
Required Tools and Equipment
You need the following tools and equipment to install the blower module:
•A Number 2 Phillips screwdriver
•3/16-inch flat-blade screwdriver
•An electrostatic discharge (ESD) preventive wrist or ankle strap with connection cord
Replacing the Blower Module
This section describes how to replace the blower module in the Cisco 10000 chassis. It contains the following procedures:
Removing the Front Cover
Use the following procedure to remove the front cover from the system. If your system does not use a front cover, go to "Replacing the Blower Module" section.
Step 1 Unlock each bezel plug by inserting the tip of a flat-blade screwdriver between the top and bottom sections of the plug, and then rotating the screwdriver to unlock the top portion of the plug (Figure 2).
Repeat this procedure for all four bezel plugs and then remove the plugs.
Figure 2 Unlocking the Bezel Plugs
Step 2 Remove the cover by lifting it up slightly and then pulling it toward you (Figure 3).
Figure 3 Removing the Front Cover
Replacing the Blower Module
Use the following procedure to replace a blower module. The blower module supports hot-swapping (for up to 2 minutes) and can be replaced without interruption to system operation.
Caution To prevent the possibility of the system overheating, be sure that the replacement blower module is out of its box and packaging, so it is ready to install as soon as the defective module is removed.
Step 1 Attach an antistatic wrist strap to your wrist and to an ESD socket on the chassis, or to a bare metal surface on the chassis or frame (Figure 4).
Figure 4 ESD Chassis Connection
Step 2 Move any interface cables from the cable brackets on the blower so they are out of your work area, and then remove the cable brackets from the blower (Figure 5).
Figure 5 Removing the Cable Brackets
Step 3 Loosen the captive screws on each side of the blower module and slide the module out of the chassis (Figure 6).
Figure 6 Removing the Blower Module
Step 4 Slide the new blower module all the way into the chassis to ensure a secure connection to the backplane (Figure 7).
Figure 7 Installing the Blower Module
The FANS OK LED should light (green). See the "Troubleshooting the Installation" section if the FANS OK LED is not on.
Step 5 Tighten the captive screws on each side of the blower module (see Figure 6).
Step 6 Rerun all interface cables through the cable management brackets and replace the front cover if necessary.
Troubleshooting the Installation
Follow the instructions in Table 1 to troubleshoot the blower module installation.

Symptom Possible Cause Corrective Action
Power Entry Modules (PEMs), fans, and other line cards are not operating
1. Disconnected power cord.
2. Power switch is in the Off position.
1. Check that all power cords are properly connected to both the Cisco 10000 system and at the power connection end.
2. Set the PEM power switches to the On position.
Fan failure LED comes on (yellow)
1. The blower module is not properly seated.
2. Blower module cable is not connected.
1. Reseat the blower module be sure that the captive screws have been tightened.
2. Remove the rear safety cover and make sure the blower module cable is connected securely (Figure 8).

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 users will be required to correct the interference at their 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.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
