When to Use This Chapter
This chapter describes routine maintenance tasks required for NonStop systems.
Monitoring Physical Facilities
This section explains how to check the physical environment of your computer facility. You might
be asked to monitor these aspects of your physical facility:
• Air temperature and humidity
• Physical security
• Order and cleanliness
• Fire-protection systems
Checking Air Temperature and Humidity
Check that the temperature and humidity are at the correct level established by management
personnel. Monitor any sensors that control temperature and humidity. Your computer environment
should have information posted that lists the names and telephone numbers of individuals that
operators can call when a malfunction occurs with the heating, air conditioning, and humidity
systems.
Checking Physical Security
Your company’s security policy will guide you in the kind of security monitoring you perform. You
might be asked to check doors and windows at the beginning and end of your shift and report
the presence of unauthorized persons. In some facilities, operations staff might be responsible for
monitoring and maintaining electronic security systems.
Maintaining Order and Cleanliness
Clutter and debris can cause accidents and fires. Dust, smoke, and spilled liquids can damage
system hardware components. Depending on your company’s policies, you might be asked to
keep the computer room clean; inspect air filters; keep printer dust under control through periodic
vacuuming; and enforce a ban on smoking, eating, and drinking in the computer room.
