This chapter describes periodic maintenance procedures, troubleshooting information for
isolating malfunctions to the assembly level, and procedures for removing and replacing various
computer assemblies.
Electrical Safety
Before proceeding with any maintenance or service on the computer which requires physical
contact with electrical or electronic components, be sure that either power is removed or that
safety precautions are followed to protect against shock. Heed all "WARNING" signs on
equipment and in this manual. All service work must be done by qualified personnel.
Periodic Maintenance
Warning
G
High voltages are present in the system equipment. Always discon-
nect power before performing any maintenance. Failure to do this
could result in serious injury.
Maintenance schedules should be set up according to the quality of the environment in which the
computer is operating. A computer in a clean and air-conditioned atmosphere requires less
periodic maintenance than one that is located in an atmosphere laden with dust, smoke, moisture,
or other particulate matter. Consult the service manuals for any peripherals for the procedures
required for a preventive maintenance schedule.
Perform the following steps as often as necessary:
1.
Clean the cabinet exterior and interior.
2.
Check the ventilating fans for proper operation. The fans have sealed bearings and need no
lubrication.
3.
Clean the computer air filter by washing it in a solution of warm water and mild soap. Dry
the filter thoroughly before you re-install it.
