Hardware Diagnostic Tests

Testing the Switch by Resetting It

If you believe the switch is not operating correctly, you can reset the switch

to test its circuitry and operating code. To perform a reset, power cycle the

switch; unplug the power cord, wait 2 seconds, then reconnect power.

Power cycling the switch causes the switch to perform its power-on self test.

Testing Twisted-Pair Cabling

Network cables that fail to provide a link or provide an unreliable link between

the switch and the connected network device may not be compatible with the

IEEE 802.3 Type 10Base-T, 100Base-TX, or 1000Base-T standards. The twisted-

pair cables attached to the switch must be compatible with the appropriate

standards. To verify your cable is compatible with these standards, use a

qualified cable test device.

Testing End-to-End Network Communications

Both the switch and the cabling can be tested by running an end-to-end

communications test—a test that sends known data from one network device

to another through the switch. For example, if you have two PCs on the

network that have LAN adapters between which you can run a link-level test

or Ping test through the switch, you can use this test to verify that the entire

communication path between the two PCs is functioning correctly. See your

LAN adapter documentation for more information on running a link test or

Ping test.
