Cisco 12006 and Cisco 12406 Router Blower Module and Air Filter Replacement Instructions
Product Number: GSR6-BLOWER=, 12000/6-BLOWER=, ACS-GSR6-FLTR=
This guide contains removal and replacement procedures for blower module and air filters in a Cisco 12006 or Cisco 12406 Router. Unless otherwise noted, all information in this publication applies to both router models.
Note The illustrations in this guide represent both the original and newer enhanced capacity blower modules, and air filters for the Cisco 12006 or Cisco 12406 router. 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. For clarity, most chassis covers are not shown in the illustrations.
Blower Module Compatibility
Two types of blower modules are used for the Cisco 12006 and Cisco 12406 routers; blowers that shipped with original systems, and enhanced capacity blowers that ship with current systems. If you are replacing an:
•Original blower module (GSR6-BLOWER=)—Use an original blower module or an enhanced capacity blower module as a replacement.
•Enhanced capacity blower module (12000/6-BLOWER=)—Use an enhanced capacity blower module as a replacement.
Note Compared to the original blower modules that shipped with Cisco 12006 and Cisco 12406 routers, airflow capacity for new enhanced blower modules is increased by nearly 40 percent to provide additional cooling to the chassis. The new fans operate at a higher speed to provide improved airflow, so you may notice increased sound generated from the new blower module.
Prerequisites and Preparation
Before you perform any of the procedures in this guide, we recommend:
•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 the Cisco 12000 Series Router publication that shipped with the router (78-4347-xx)
–Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide
For additional information about obtaining documentation see the "Obtaining Documentation" section.
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 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.
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. Ensure the measurement is 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
The blower module supports online insertion and removal (OIR), so you can remove and install the blower module while the system remains powered on without presenting an electrical hazard or damage to the system. 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 OIR and can be replaced without interruption to system operation, do not operate the system 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:
•Number 2 Phillips screwdriver
•3/16-inch flat-blade screwdriver
•An electrostatic discharge (ESD) preventive wrist or ankle strap with connection cord
•Vacuum cleaner (to clean the air filters)
Removing and Replacing the Blower Module
Use the following procedure to remove and replace the blower module.
Step 1 Remove the blower module from the chassis (Figure 2):
a. Lift the blower module handle to its carrying position.
b. Loosen the four captive screws on the blower module faceplate.
c. Remove the blower module by grasping it on each side and pulling it straight back from the chassis.
Figure 2 Removing the Blower Module
Step 2 Install the new blower module (Figure 3):
a. Position the alignment holes on the blower module with the guide pins at the top of the chassis and on the PDU at the bottom of the chassis.
b. Slide the blower toward the chassis until it mates with the backplane connector.
Caution Electrical and control line connections for the blower module and backplane occur automatically when the connectors on the blower module and PDU mate. To prevent damage to the blower module and PDU connectors, do not use excessive force when installing the blower module against the rear of the chassis.
c. Tighten the four captive screws to secure the blower module to the chassis.
The (green) OK indicator should light. If the OK indicator does not light, see the "Troubleshooting the Installation" section.
d. Lower the blower module handle to its operating position.
Figure 3 Installing the Blower Module
Troubleshooting the Installation
Use the following procedure to troubleshoot the blower module if it is not operating properly after installation.
Step 1 Be sure the router is powered on and that all power cords are connected properly.
Step 2 Loosen the four captive screws and reseat the blower module to the chassis. Retighten the captive screws to ensure the blower module is properly seated to the backplane connector.
Step 3 Check the blower module status indicators:
•OK (green)—This indicator should light as soon as the blower module is installed and receives power from the backplane connector. It indicates that the blower module is operating normally.
•Fail (red)—This indicator remains off during normal operation. If the indicator is on, the system has detected a fan failure or other fault in the blower module.
–If this indicator remains on and the blower module fans fail to operate normally after several attempts to reseat the blower module, replace the existing blower module with a spare.
–If the spare blower module also fails, power off the router and contact a Cisco service representative for assistance.
Cleaning or Replacing the Air Filters
The Cisco 12006 and Cisco 12406 routers are equipped with two user-serviceable air filters that remove dust drawn into the router by the blower module. One time per month (or more often in dusty environments), examine the air filters.
Use the following procedure to clean or replace the air filters.
Step 1 Open the spring-loaded air filter door on the right side of the chassis and remove an air filter by pulling the small tab on the edge of the filter (Figure 4).
Remove the second air filter the same way.
Figure 4 Removing the Air Filters
Step 2 Visually check the condition of the air filters to determine whether to clean them or install new replacements.
•Dirty—You can vacuum or replace the filters.
Caution Do not try to vacuum the air filter while it is installed in the chassis. You must remove the air filter completely before you clean it to prevent contaminants from being drawn into the router.
•Worn or torn—If the filters appear worn or torn, dispose of them in a responsible manner and install replacement air filters (ACS-GSR6-FLTR=).
Step 3 Open the air filter door and install the new or cleaned air filters.
Note An arrow located on the edge of each air filter frame that indicates the direction of air flow. Always install the air filter with the arrow pointing in toward the RP and line card cage.
