Cooling System Functional Description
Slot Fillers
To maintain optimum cooling performance in the chassis and at the slot level, unused slots must be filled
with card blanks or flow restrictors. These slot fillers are simple sheet metal only and are not active.
Software cannot detect their presence.
Chassis Air Filter
The chassis air filters in the Cisco ASR 9000 Series Routers are NEBS compliant. The filter is not
serviceable but is a field replaceable unit. Replacing the filter does not interrupt service.
In the Cisco ASR 9010 Router, a chassis air filter is located underneath the fan trays (see Figure 2-73).
