Chapter 3 Periodic Maintenance 3-3
Note – One concern about cleaning the air filters while power to the server is on is
that dislodged dust may be sucked inside the system when the air filters are pulled
out. Therefore, gently and slowly pull them out. Complete the cleaning as quickly as
possible.
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.
Because the structure and the mounting environment of air filters are the same, the
descriptions in the figures covering filter cleaning refer to, as an example, the air
filters at the front of each model.
1. Unlock and open the front and rear doors of the server. For details, see
Chapter 5.
2. Using a Phillips screwdriver, loosen the screw securing the fixing bracket of an
air filter, and turn the bracket so that it faces downward.
