Dealing with the Physical Chapter 10

• Dr. Lauren B. Eder
• CIS 400 Spring 2004

2
Overview

• Installing physical networks
• Diagnostics

3
Installing Physical Networks

• Planning the installation
• Mapping the cables
• The equipment room
• Cable installation
• Making connections
• Labeling the cable
• Testing the cable runs

4
Planning the Installation

• Structured network cabling requires a series of
  work areas and an equipment room.
• A cable drop is the location where the cable
  comes out of the wall.
• It is advisable to map the cable runs keeping in
  mind the floor plan of the building, before
  installing the network.

5
Mapping the Cables

• Raceway products are used as a preferred
  alternative to running cables into a wall.
• Outlets are openings connecting cables running
  inside walls.

6
The Equipment Room

• The factors considered in deciding the location
  for the equipment are
• Distance
• Power
• Low humidity
• Cool environment
• Access
• Expandability

7
Cable Installation

• It involves extending a cable from the equipment
  room to the users desk.
• Telescoping poles, pull strings, and crossbows
  are used for pulling cables.
• Hooks and trays are used for better cable
  management, safety, and protection from ESD.

8
Making Connections

• Connecting the work areas
• Connecting the patch panels

9
Connecting the Work Areas

• It involves crimping jacks to the end of wire
  using the 110-punchdown connection.

10
Connecting the Patch Panels

• Cable management
• Plastic D-rings guide the patch cables neatly
  along the sides and front of the patch panel.
• Organize patch panels to mirror network layout
  physically or logically.

11
Labeling the Cable

• Labeling and documenting the cable installation
  reduces problems during network repair.
• Label on the outlet should match with that of the
  patch panel.

12
Testing the Cable Runs

• Verify that each jack has been properly
  connected.
• Check whether the cable can handle the speed of
  the network.
• Cable testers can be used for checking the cable
  length, broken ends, or interference depending on
  its type.

13
Testing the Cable Runs

• Continuity testers are used for checking
  connectivity between cables.
• Time Domain Reflectometers (TDR) are used for
  determining cable length.
• Protocol analyzers are used for checking IP
  address, MAC address, and IPX address.

14
Diagnostics

• Synopsis
• Toners

15
Synopsis

• Double-check the Network Interface Card (NIC)
  driver.
• Check for cable problems and NIC link lights.
• Check for defective patch cables.
• Check for problems with user logon name and
  password.
• Check for cable continuity from the PC to the
  equipment.

16
Toners

• They are devices used for tracing cables.
• They are comprised of two separate devices - the
  tone generator and the tone probe.
• The tone generator sends an electrical signal
  down the wire, and tone probe emits a sound when
  placed near the cable to which tone generator is
  connected.
• Advanced toners provide phone jack for
  communication.

17
Summary

• Installing a structured cabling system involves
  three discrete steps planning, pulling the
  cable, and connecting.
• Planning involves placement and connection of
  components on the network.

18
Summary

• Connecting cables requires crimping, connecting
  jacks, and testing for continuity.
• Cable connection involves cable management,
  labeling, and testing.
