Checking Physical Security
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.
Cleaning System Components
This subsection contains basic information about cleaning enclosures, printers, and
tape drives. Many companies have service-level agreements with HP that include
regular preventive maintenance (PM) of their hardware components. If a Field Service
Organization (FSO) representative handles cleaning and other preventive maintenance
for your company, you need not be concerned with the cleaning tasks mentioned here.
Cleaning an Enclosure
Cleaning an enclosure is an infrequent task that you perform as required by conditions
at your site. Many installations require only occasional dusting. To dust an enclosure,
use a lint-free, antistatic dust cloth.
If you need to clean an enclosure, use a cotton cloth and a cleaning product
formulated for computer equipment. Or use a damp cotton cloth and a mild,
nonabrasive soap.
Cleaning and Maintaining Printers
Inspect all printers and replace the ribbons on line printers as needed. Replace the
toner cartridges of laser printers that are shared by the user community when print
quality lessens. To remove paper dust that can affect printer operation, vacuum
printers periodically.
Caution. Do not use solvents or spray products on any part of an enclosure.
