Electrical Considerations
Because computer hardware is extremely sensitive to electrical and magnetic
fields, a few special precautions should be taken. The hardware should be plugged
into clean lines only. Do not plug the CPU into a outlet, which is already being
used for other hardware (i.e., air conditioners, thermostatic devices, saws). Also
avoid having objects with magnetic fields near the CPU and terminals (decorative
magnets, cellular phones, etc.).
Use anti-static carpeting, anti-static mats, or anti-static carpet sprays to eliminate
problems caused by static discharges near system components. These products
are available through any major supplier of commercial floor covering or computer
supplies.
You should also use electronic surge protectors. Power surges commonly occur
when lightning strikes a nearby power line, when the lights switch off, or during
utility line maintenance. You can’t prevent these circumstances but you can
protect your computer equipment from damage. Surge protectors provide full
surge suppression and also filter out conducted noise on power lines that can
interfere with computer memory. These devices are not lightning arrestors. They
will not afford protection in those rare instances when lightning actually strikes
the building, service entrance, or antenna.
Phone Requirements
Ø Modem Line Requirements
Your modem is to be connected to your system. It is required that you have a
single-line phone with a modular jack (RJ11C) that does not go through your
switch board. This modem jack must be located near the main CPU (within
15’). This phone line could be shared with a fax machine. If you do share the
line with a fax machine, you will need a switching device (A/B switch) to allow
automatic switching from fax to modem and back.
Ø Phone Line Requirements
A regular phone line(which can go through your switchboard) needs to be
located next to the main computer system. At times during support calls, you
will need to be seated at the main CPU. This is a great help to you and the
Dimensions support staff.
