This publication contains removal and replacement procedures for the blower module and chassis air
filter in Cisco 12016, Cisco 12416, and Cisco 128 16 routers. Unless otherwise noted, all information in
this publication applies to all router models.
NoteThe 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 sy stems, and enhanced capacity blowers that ship wi th
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.
• Enhanced capacity blower module (12000/10/16-BLWER=)—Use an enhanced capacity blower
module as a replacement.

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 f ailures. 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 conta ct.
NoteY ou should periodically check the resistance value of the ESD-prev entive strap. Ensure the measurement
is between 1 and 10 megohms.
Before performing the procedures in this guide, att ach an ESD-preven tive strap to your wr ist and connect
the leash to the chassis or to another grounded, bare metal surface as shown in Figure 1.

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.
