Periodic Maintenance

Caution – The information in this chapter and subsequent chapters is intended for use by
authorized service engineers only. For non-authorized field engineers, this information is for
reference only.
This chapter explains the maintenance work that must be performed regularly regardless of
whether a problem has occurred. The actual work is limited to preventing dust in the
environment from creating pollution.
This information is explained in the following sections:
Section 3.1, "Cleaning a Tape Drive Unit" on page 3-1
■
Section 3.2, "Cleaning an Air Filter (Server)" on page 3-2
■
Section 3.3, "Cleaning an Air Filter (I/O Unit)" on page 3-5
■
The high-end server is equipped with air filters at the bottom of the cabinet. These air filters
filter out dust particles from the air that the fans suck in from the floor into the cabinet. If the
filters become clogged, the ventilation volume is reduced and the temperature rises, leading
to problems. Although the frequency of cleaning varies with the operating environment, the
air filters must be cleaned on a regular basis to ensure that they do not become clogged with
dust. Each I/O unit also has air filters. Clean them at the same time that the air filters of the
server are cleaned.
When the service life expiration date of an air filter has already passed, replace it by
referring to the air filter cleaning procedure.
