3.3 Cleaning an Air Filter (I/O Unit)
Each I/O unit has two air filters. Clean them at the same time that the air filters of
the server are cleaned.
Caution – If you must use a vacuum cleaner for this work, use it outside the
computer room. Do not use it inside the computer room. Using a vacuum cleaner
inside the computer room may result in a server failure.
The cleaning procedure is as follows.
1. Loosen the screws securing the filter cover, and remove the filter cover.
2. Pull out the air filter from the filter cover.
