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.
