Cleaning and Replacing the Cisco 7507 and Cisco
In the Cisco 7507 and Cisco
Caution Do not operate the system for more than 5 minutes without a filter installed. Never place a wet filter in the chassis; the moisture drawn into the chassis can damage the equipment.
You need to remove the bottom front chassis panel to access and remove the filter, and then move the filter away from the chassis for vacuuming. Vacuuming can dislodge substantial amounts of dust, and cleaning the filter near the opened chassis can allow loose particles to enter the chassis through the unfiltered blower. Therefore, we recommend that you briefly remove the panel to clean it, and then immediately replace it in the chassis.
Use the following procedure to check the air filter and clean or replace it if necessary:
Step 1 Remove the bottom front panel. (See Step 1 through Step 6 in the procedure for removing front cover panels in the “Removing and Replacing the Cisco 7507 and Cisco
Step 2 Remove the filter by grasping it in the center and pulling the edges out of the frame.
Step 3 Check the condition of the filter. If the filter is extremely dusty, or if it appears worn or torn, discard it after you ensure that you have a replacement available. Proceed to Step 7 to install the new filter.
Step 4 Move the filter away from the chassis and vacuum it thoroughly. Do not vacuum the filter when it is installed or near the chassis opening; doing so can dislodge substantial amounts of dust and allow loose particles to enter the chassis.
Step 5 If the filter needs washing, refer to Step 7 to install a temporary replacement filter. If a replacement is not available, shut down the system until the filter dries and you can safely replace it.
Step 6 Wash the filter in running water, or discard it and replace it with a new filter. The filter must be thoroughly dry before you replace it in the chassis.
Step 7 Place the new or clean, dry filter (or a temporary replacement filter) over the frame and push the edges into the frame with your fingers. Ensure that all edges are tucked into the frame.
Step 8 Replace the bottom front panel by aligning the bottom of the panel with the holes on the front of the chassis. Push the edges in until the ball studs snap into place.
Caution Never place a wet filter in the chassis; the moisture drawn into the chassis can damage the equipment.
