Network Troubleshooting
Network Administrator's Toolkit

  The Network Administrator's Toolkit should contain, besides the usual basic toolkit, some of the following tools:-
  • RJ-45 Crimping Tool. (A decent one, not a Radio Shack plastic one that will not crimp reliably, or break a few times after it has been used)

  • Crossover cable (Useful for connecting two nodes, for transmit & receive, without a connectivity device)

  • Tone Generator and Locator (Sometimes called a "Fox & Hound") (Especially useful for identifying cables in a patch panel or closet)

  • Multimeter

  • Cable Tester(s)
    Depending on the cable type and its use, there are basically two types of cable tester:-
    • Simple continuity tester - to determine electrical connectivity issues (open circuit, short, etc.)
    • Complex cable integrity tester - to evaluate cable's effectiveness for specific signal transmission

  • Loopback adaptor(s) (Different types for different connector types. RJ-45 ethernet is the most common)

  • Wireless Network Tester

  • Software tools that can be useful include:-
    • Network Monitors
    • Protocol Analyzers
