assembly.
Inspect, Clean, and Replace the Reusable Air Filter
Before you begin
To complete this task, you need a vacuum cleaner or detergent and water faucet, a spare filter, and a pinned
hex key.
Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry
could constitute an energy hazard. Statement 206

Although the filter works if it is installed with either side facing up, Cisco recommends that you install it with
the metal bracing facing up to preserve the surface of the filter.
