Preventive, Corrective & File Maintenance
3.1.4
Cable Inspection
Cabling problems are the most prevalent cause of datacomm failure between the VU-ACD/100 host and
peripheral devices. Most cable problems are identified and resolved during the installation process.
However, cable problems can develop as a result of typical Call Center activities, such as moving/adding
equipment, changing cable connections, bumping into remote terminals, modems, printers, etc.
It is a good practice to inspect and tighten datacomm and telco cables and connectors on a periodic basis.
The best time to do so is when cleaning equipment or maintaining printers. Verify that the cable has not
been damaged by errant furniture, construction/ renovation, cable mining operations or other end-user
activities. Wiggle connectors – they should be firmly secured to the device(s). Replace damaged cables/-
connectors when discovered.
In VU-ACD/100 configurations employing LAN Connectivity, inspection, maintenance and upgrade of
LAN media, hubs, routers and bridges is the responsibility of the LAN administrator.

General Cleaning
3.1.5.1
Video Monitor & Keyboard
The monitor screen of the host and remote terminals should be cleaned using a lint-free cloth and a clean-
ing solution formulated for this purpose. Do not spray the solution on the screen. Dampen the cloth and
wipe away fingerprints and dust.
The monitor housing can be cleaned with a mild soap solution on a damp cloth. Do not soak the cloth
with the solution; excess moisture could drip or linger on external surfaces.
The keyboard can be wiped with a soft bristle brush and/or vacuumed to remove dust and debris. Use
cotton swaps dipped in isopropyl (rubbing) alcohol to clean the keycaps.
3.1.5.2
Cabinet Exteriors
The exterior surfaces of the host and remote terminal CPUs, printers, modems and external displays can
be wiped clean with a cloth dampened with mild detergent (dish washing liquid). Finish cleaning by
rubbing the surfaces with a dry, lint-free cloth.
!
Never spray cleaning solutions on or into electronic devices. The spray
may contact live electrical components causing severe damage to compo-
nents and possible injury to the user.
3.1.5.3
Floppy Disk/Cartridge Tape Drives
The magnetic heads in floppy and cartridge tape drives build up a thin film of magnetic oxide during
operation. Eventually this residue can create problems reading/writing from/to the storage media.
Follow the manufacturer’s recommendations for cleaning procedures. Floppy disk and cartridge tape
cleaning kits are available from OEM sources.
!
DAT and QIC MLR tape drives require more frequent cleaning than standard
QIC tape drives. Refer to the cleaning instructions contained in the OEM
Installation Guide supplied with the tape drive for detailed cleaning
instructions.
3.1.5.4
CPU Interior
If the VU-ACD/100 host and/or remote terminals are located in an environment where dust is a problem,
Perimeter Technology recommends opening the CPU chassis and vacuuming out the film of dust which
tends to coat interior components. Personal computers draw air into and through the CPU chassis to cool
heat producing components. Over time, the dust particles in the air are deposited on the power supply,
circuit cards and motherboard. The dust layer inhibits cooling and can cause component failure.
!
Always turn off power to the CPU and disconnect the AC line cord prior to
opening the chassis. Observe anti-static precautions to prevent damage to
sensitive electronic components.
