Installation guide

• New air filter
• A #2 Phillips screwdriver
Removing an air filter
Complete the following steps to remove a front air filter from the chassis.
1. While holding the air filter in place, unscrew the four captive mounting screws using the #2 Phillips
screwdriver.
2. Carefully remove the air filter from the chassis.
To avoid having captured particulates drawn into the chassis, remove the filter in a fashion that
maintains the orientation of the filter relative to the system until the filter is 12 inches away from the
intake.
Replacing an air filter
Complete the following steps to mount the new front air filter on the chassis.
1. Orient the new filter over the four mounting holes using the screws as guides.
Be sure the side marked BOTTOM is on the bottom.
2. Using the #2 Phillips screwdriver, initiate the threads, two turns per screw, until all four are started.
3. Tighten all four screws, one at a time.
Do not overtighten the screws as this will compromise the frame, admitting unfiltered air.
Module filler panel removal and replacement
Each removable module in the chassis (except the fans) has a matching filler panel that must be in
place if no module is installed in a slot. This includes management modules, switch fabric modules,
line cards, and power supplies. There are no filler panels for the fans because all fans must be
installed on the chassis.
CAUTION
If you do not install a module or a power supply in a slot, you must keep the slot filler panel in
place. If you run the chassis with an uncovered slot, the system will overheat.
Removing a filler panel
A filler panel should be removed only when being replaced with a new module or another filler panel.
Any slot that is not occupied by a module should be occupied by a filler panel to ensure proper cooling
of the chassis and protection from dust.
CAUTION
If you do not install a module or a power supply in a slot, you must keep the slot filler panel in
place. If you run the chassis with an uncovered slot, the system will overheat.
Filler panels for the management module and switch fabric module are the same. The filler panel for
the line card slot is similar, though larger. Both the management module and switch fabric module
