4100/4120-6014, 4100-6078 NICs and 4100/4120-Series Media Modules Installation Instruction
Wiring
The type of wiring used depends on the type of media cards being used in the system. The only time the motherboard terminals are used is when
wired media cards are plugged into the daughter card. Otherwise, modem and fiber connections are made straight to and from the media cards.

General Guidelines

Make sure these guidelines are accounted for before wiring:
• All wires must be 18 AWG, or as the local code dictates.
• Conductors must test free of all grounds.
• All wiring must be done using copper conductors only, unless noted otherwise.
• If shielded wire is used,
- The metallic continuity of the shield must be maintained throughout the entire cable length.
- The entire length of the cable must have a resistance greater than 1 Megohm to earth ground.
• Underground wiring must be free of all water.
• In areas of high lightning activity, or in areas that have large power surges, the 2081-9027 Transient Suppressor should be used on monitor
points.
• Wires must not be run through elevator shafts.
• Wires that run in plenum must be in conduit.
• Splicing is permitted. All spliced connections must either be soldered (resin-core solder), crimped in metal sleeves, or encapsulated with an
epoxy resin. When soldering or crimped metal sleeves are used, the junction must be insulated with a high-grade electrical tape that is as
sound as the original insulating jacket. Shield continuity must be maintained throughout.
• A system ground must be provided for earth detection and lightning protection devices. This connection must comply with approved earth
detection per NFPA780.
• Only system wiring can be run together in the same conduit.

Power-Limited Guidelines

Make sure these guidelines are accounted for before wiring for power-limited systems:
• Non-power limited field wiring (AC power, batteries, City connection) must be installed and routed in the shaded areas shown in Figure 17.
• Power-limited field wiring must be installed and routed in the non-shaded areas shown in Figure 17, with the exception of City wiring.
• Excess slack should be kept to a minimum inside the back box enclosure. The wiring should be neatly dressed and bundled together using the
wire ties provided with the equipment. Anchor power-limited wiring to tie points, as shown in Figure 17.
• Tie the wiring located between bays to the internal wiring troughs, if applicable.
