Installation Guidelines

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.
Although the blower module supports OIR and can be replaced without interruption to system operation,
Caution
the system should not operate without a blower module for more than 3 minutes to prevent overheating.
Caution
You 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:
