Cisco 12016, Cisco 12416, and Cisco 12816 Router Blower Module and Air Filter Replacement Instructions
Cisco Product Numbers: GSR16-BLOWER=, 12000/10/16-BLWER=, ACS-GSR16-FLTR=
This publication contains removal and replacement procedures for the blower module and chassis air filter in Cisco 12016, Cisco 12416, and Cisco 12816 routers. Unless otherwise noted, all information in this publication applies to all router models.
Note
The illustrations in this guide represent both the original and newer enhanced capacity blower modules, and air filters for the Cisco 12016, Cisco 12416, and Cisco 12816 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. For clarity, most chassis covers are not shown in the illustrations.
Blower Module Compatibility
There are currently two types of blower modules in use for the Cisco 12016, Cisco 12416, and Cisco 12816 routers; blowers that shipped with original systems, and enhanced capacity blowers that ship with current systems.
If you are replacing an:
•
Original blower module (GSR16-BLOWER=)—Use an original blower module or enhanced capacity blower modules as replacements.
CautionYou cannot mix original and enhanced capacity blower modules in the same chassis. Both the upper and lower blower modules must be identical.
•

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 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
Installation Guidelines
The blower modules support online insertion and removal (OIR), so you can remove and install a blower module while the system remains powered on without presenting an electrical hazard or damage to the system. You can replace a blower module while the system maintains all routing information and ensures session preservation.
CautionAlthough the blower module supports OIR and can be replaced without interruption to system operation, the system should not operate without a blower module for more than 3 minutes to prevent overheating.
CautionYou cannot mix blower types within the chassis. If you are replacing a blower module from an old system (GSR16-BLOWER=), you must replace both upper and lower blower modules with new, higher capacity replacement blowers (12000/10/16-BLWER=). Although the blower modules can be replaced without interruption to system operation, the system should not operate with mixed blower modules in the router for more than 5 minutes.
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 Modules
This section contains the procedure to remove and replace the upper or lower blower modules from the chassis. Before beginning either of these procedures, be sure to read the "Installation Guidelines" section.
Upper and Lower Blower Module Orientation
Illustrations in this procedure show the removal and replacement of the upper blower module. The procedure to replace the lower blower module is the same except for the orientation of the blower module.
•
Heads-up orientation—Install the blower module in the upper bay in the "heads-up" orientation with the three fan air intake openings face down.
•
Heads-down orientation—Install the blower module in the lower blower module bay in the "heads-down" orientation with the three fan air intake openings face up.
Use the following procedure to remove and replace the blower modules.
Step 1
Remove the blower module from the chassis (Figure 2):
a.
Loosen the captive screw on each side of the blower module.
b.
Pull out the blower module halfway from the module bay.
c.
Slide out the blower module completely from the module bay while supporting it with your other hand.
Warning
The blower module weighs approximately 20 pounds (9 kg). Use two hands when handling the blower module.
Figure 2 Removing the Upper Blower Module
Step 2
Install the new blower module into the chassis (Figure 3):
a.
Lift the blower module (with two hands) and slide it halfway into the module bay.
b.
Slowly push the blower module into the chassis until it mates with the backplane connector at the back of the module bay.
CautionTo prevent damage to the connectors, do not use excessive force when inserting the blower module into the chassis.
c.
Tighten the captive screws on the blower module to secure it to the chassis.
•
The (green) OK status indicator on the front of the blower module should light. If the OK indicator does not light, see the "Troubleshooting the Installation" section.
Figure 3 Installing the Upper Blower Module
Troubleshooting the Installation
Use the following procedure to troubleshoot a 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 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)—Indicates that the blower module is operating normally. This indicator should light as soon as the blower module is installed and receives power from the backplane connector.
–
If this indicator remains on, and the blower module fans fail to operate after several attempts to reseat the blower module, replace it with a spare.
–
If the spare blower module also fails, power off the router and contact a Cisco service representative for assistance.
•
FAIL (red)—This indicator remains off during normal operation. If this 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 after several attempts to reseat the blower module, replace it 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 Chassis Air Filter
The Cisco 12016, Cisco 12416, and Cisco 12816 routers are equipped a user-serviceable air filter that removes dust drawn into the router. One time per month (or more often in dusty environments), examine the air filter for damage and cleanliness.
CautionDamage to the air filter can restrict the airflow, cause overheating in the router, and degrade EMI performance. Be careful when cleaning and replacing the filter.
Use the following procedure to clean or replace the air filter.
Step 1
Loosen the captive screws on the air filter door and pivot the door open (Figure 4).
CautionIf the router uses an extended front cover bezel, the air filter door does not have enough space to open completely. Before you open the air filter door, you must remove the extended front cover.
Figure 4 Opening the Chassis Air Filter Door
Step 2
Lift up the air filter and carefully slide it out the door (Figure 5).
CautionBe careful not to damage the honeycomb screens on the back of the air filter door and in the fabric card cage. Damage to the honeycomb screens can restrict airflow, cause overheating, and affect EMI performance.
Figure 5 Removing the Chassis Air Filter
Step 3
Visually check the condition of the air filter to determine whether to clean or install a new replacement.
•
Dirty—You can vacuum or replace the filter.
CautionDo not 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 bays or cage.
•
Worn or torn—If the filter appears worn or torn, dispose of it in a responsible manner and install a replacement air filter (ACS-GSR16-FLTR=).
Step 4
Position the metal braces on the back of the air filter to face toward the switch fabric and alarm card cage. Slide the new or cleaned air filter into the air filter door (Figure 6).
Figure 6 Installing the Chassis Air Filter
Step 5
Lift up the air filter door so that the four guide pins are inserted in the corresponding holes on each side of the switch fabric card cage (Figure 7).
CautionAlign and seat the door carefully to avoid damaging the EMI-preventive gasket contacts on the door.
