Safety procedures:Safety procedures: Electrical. Electrical.

• Never work on a device (e.g. hub, switch, router, or PC) with the case open and the line voltage (power cord) plugged in.

• Test electrical sockets with an appropriate voltage tester or multimeter.

• Locate all electrical conduits and power wires before trying to install any networking cable.

• Properly ground all networking equipment.

• Never cut or nick a live 120 or 220 VAC line.

• Wear safety glasses whenever you are drilling or cutting.

• Measure carefully before you cut, drill into, or permanently alter construction materials.

• Investigate what you will be drilling or cutting into before you begin.

• Follow practices of general cleanliness (e.g. minimize dust that can affect sensitive networking devices).

• Follow proper ladder placement and safety procedures whenever you must use a ladder.

Safety rulesSafety rules

• Turn off power to all circuits that might pass through those work areas.

• Before you begin work, learn the locations of all fire extinguishers in the area.

• Wear appropriate clothing. Long pants and sleeves help protect your arms and legs. Avoid wearing excessively loose or baggy clothing.

• If you anticipate working in a dropped ceiling area, survey the area. You can do this by lifting a few of the ceiling tiles and looking around. This will help you locate electrical conduit, air ducts, mechanical equipment, and anything that might possibly cause problems later.

Safety rules (cont.)Safety rules (cont.)

• If you need to cut or saw, protect your eyes with safety glasses. It's also a good idea to wear safety glasses when you work in a crawl space or above a dropped ceiling.

• Consult the building's maintenance engineer to find out if it there is asbestos, lead, or PCB where you will be working. If so, follow all government regulations in dealing with that material.

• Keep your work area orderly and neat. Do not leave tools lying in places where someone might trip over them. Use caution with tools that have long extension cords. Like tools, they are easy to trip over.

Laying wires in patch panelLaying wires in patch panel

1. 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.

2. Keep the ends of the cable centered above the pin locations.

3. Be sure to keep the jacket within 6.4 mm of the pin locations you are working on, in order to avoid exposing too much wire.

4. You must not untwist the wire pairs any more than necessary.
