Replacing the Chassis Air Filter
Powering Off the Router
Caution
Do not turn off the switch on the power tray to remove individual power modules. Power modules
support OIR, so they can be removed and replaced with the power on and the system operating.
support OIR, so they can be removed and replaced with the power on and the system operating.
If it becomes necessary to turn all power off to the router, follow these steps:
Step 1
Set the power switch on each power tray to the off (0) position.
Step 2
Power off all circuit breakers for the source power lines connected to the power trays.
Step 3
Verify that the Pwr OK indicator on each power module is off.
Step 4
Verify that the OK indicator on the fan tray is off.
Replacing the Chassis Air Filter
The Cisco ASR 9000 Series Routers are equipped with user-replaceable air filters that help prevent dust
from being drawn into the router. One time per month (or more often in dusty environments), examine
the air filters for damage and cleanliness.

the air filters for damage and cleanliness.
Note
In the Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco ASR 9904 Router, the chassis air
filter is not serviceable. We recommend that you replace the filter at regular maintenance intervals. The
interval may vary between 3 and 12 months depending on the environment.

interval may vary between 3 and 12 months depending on the environment.
Note
In the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the three air filters (left, center, and right)
contain foam media which filters the air going into the chassis. The three air filters can be removed from
the chassis so that the foam media (Cisco PIDs 9922-CEN-FLTRMED= and 9922-LR-FLTRMED=) can
be replaced on a regular maintenance interval. The interval may vary between 3 and 12 months
depending on the environment.

Caution
Damage to the air filter can restrict the airflow, cause overheating in the router, and degrade
electromagnetic interference (EMI) compliance. Be careful when cleaning and replacing the filter.
