Mounting a RJ-45 jack

• TIA/EIA-568-A specifies two types of wall mounts
  that you can use to position an RJ-45 jack onto a
  wall
• The surface mount.
• The flush mount.

Laying wires in patch panel

• Lay down cable wires in ascending order, by cable
  number. Use the cable numbers that were assigned
  when it was run from the work area to the wiring
  closet.
• Keep the ends of the cable centered above the pin
  locations.
• Be sure to keep the jacket within ½ inch of the
  pin locations you are working on, in order to
  avoid exposing too much wire.
• You must not untwist the wire pairs any more than
  necessary.

24
CABLE TESTING
25
Cable Testers

• Determine cable distance.
• Locate bad connections.
• Provide wire maps for detecting crossed pairs.
• Measure signal attenuation.
• Measure near-end crosstalk. .
• Detect split pairs.
• Perform noise level tests.
• Trace cable behind walls.
