Guidelines
• Use separate wires to ground
each piece of equipment to the
ground bus bar. If a ground stud
is provided on the back of the
unit, connect it to the ground
bus bar with a dedicated ground
wire (use the gauge specified
by the manufacturer).
• Interconnect Ethernet
equipment supporting 100 Mbps
transmission with CAT 5 UTP
patch cable. Label the cables
and route them neatly through
the channels provided in the
metal rack.
CAUTION: Do not use voice
grade twisted pair interconnect
patch cable wired to standard
voice grade punch-down blocks
on an IDE.
• The metal brackets used to
connect the racks provide
mechanical connection only.
Use a dedicated ground wire to
ground each rack separately to
the ground bus bar.
• Connect the metal racks that
house the Ethernet cable to the
ground bus bar to provide an
effective shield against potential
noise sources such as power
lines and florescent lights.
• The tray should contain
Ethernet cables only. Do not mix
power cables with Ethernet
cables
