Chapter 5 Removal and Replacement Procedures
Air Filters in C7603-S Chassis
Caution
Damage to the air filter and intake panel can restrict the airflow, cause overheating in the router, and
degrade EMI performance. Be careful when cleaning and replacing the air filter.
Air Filter Maintenance
Follow the procedure described in
“Replacing the Air Filter on a Cisco 7609 Router and the Cisco
7609-S Router (Optional)” section on page 5-131
to remove and reinstall the air filter on the air filter
assembly. After taking out the air filter, visually check the condition of the air filter to determine whether
to clean or install a new replacement. If the air filter is dirty, clean the filter. Change the air filter if it is
torn or worn out.
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. The cleaning process
should be performed outside the router installation area.
You can use the pressurized air to clean the air filter. If the filter appears worn or torn, dispose of it in a
responsible manner and install a replacement air filter.
Intake Panel Maintenance
Visually check the condition of the intake panel (If the air filter assembly is fitted on the intake panel,
remove it). If the intake panel is dirty, you need to clean the panel. Remove the intake panel from the
router and take is outside the router installation area. Clean the intake panel using high presurrised air
and replace it in the router.
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. The cleaning process
should be performed outside the router installation area.
Air Filters in C7603-S Chassis
