Step 3
Visually check the condition of the air filter to determine whether to clean it or
install a new replacement.
•
Dirty—You can vacuum or replace the filter.
Caution
Do 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 (12000/16-FILTER=).
Step 4
Slide the new or cleaned air filter into the air filter door.
Step 5
Close the air filter door and tighten the 4 captive screws.
Caution
Align and seat the door carefully to avoid damaging the
EMI-preventive gasket contacts on the door. The air filter door must
be closed and secured at all times to maintain correct
EMI performance.
Removing and Replacing Blower Modules
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.
