Preventive Maintenance 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.

Caution. Do not use solvents or spray products on any part of an enclosure.

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.
