LAN cable testerTurn the testing unit on.

STEP 2

 

RJ-45 cable plugged into LAN testerPlug the ends of your RJ45-terminated cable into the tester's two ports … it doesn't matter what order you do this in.

STEP 3

 

turning the cable tester onDepending on which tester you use, the test function will be either manual or automatic. If you're using the automatic test mode, simply push the button and let the unit do its work. If you need to use a manual mode, simply hit the test button repeatedly to advance through all 8 wires.

STEP 4

 

indicator lights on the LAN cable testerYou'll see two separate bars of indicators, each with 8 lights. Watch these indicator lights as the test sequence is completed, wire-by-wire. If both the “input” and “output” indicators for each wire are brightly lit, then you know that optimum connection has been made. A dim light indicates poor connection, and no light at all lets you know that connection is not being made.
