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.
Caution
Although 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.
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:
•
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
on page 4
.
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.
