Periodic Maintenance
Caution – The information in this chapter and subsequent chapters is intended for
service engineers.
Persons other than the authorized field engineers should use this information only
for reference and should not actually perform the work.
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.
