When to Use This Section
This section describes routine maintenance tasks required for Integrity NonStop NS-series servers.
Monitoring Physical Facilities
This subsection 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.
Checking Fire-Protection Systems
You might also be asked to check the fire alarms and fire extinguisher systems in your facility.
