Guidelines
• Use CAT 5 or CAT 5e cables
(certified to TIA/EIA 568A)
• Maximum length 5 ft. (1.5 m)
• Route cable away from
sources of interference, such as
power cables
• Route cable as required for
convenience
• Route cable away from
Ethernet cables
• Use a separate power outlet
for potential noise generating
devices such as a lamp, coffee
maker, or radio
• Route cable away from
Ethernet cables
• Ballast circuitry inside
florescent lamps will create
noise spikes on power cables
when the lamps are turned off.
Ensure that florescent lamps
are plugged into dedicated
surge suppressing power bars.
Voltage limiting devices inside
the power bars reduce noise
spikes and reduce the risk of
data errors. Some desks have
power outlets that are
designated for the computer
and utility devices. These
outlets have built-in surge
protection. In this case, a power
bar is not required.
