Hardware Diagnostic Tests

Testing the Hub by Resetting It

If you believe that the hub is not operating correctly, you can reset it to test 
its circuitry and operating code. To reset a hub, either:

■

Unplug and plug back in the power cord (power cycle)

■

Press the reset button on the front of the hub

Power cycling the hub and pressing the Reset button both cause the hub to 
perform its power-on self-test, which may resolve any temporary operational 
problems.

The self-test passes if the Fault LED on the front of the hub goes off after 
approximately 3 seconds for the Hub 12 and Hub 24, and approximately 30 
seconds for the Hub 12M and Hub 24M. If the Fault LED stays on longer than 
these normal self test times, the hub may have to be replaced. Contact your 
HP-authorized dealer or HP representative for assistance. See the Customer 
Support/Warranty booklet that came with your hub for more information.

Testing Twisted-Pair Cabling

If you think the cable should work but still isn’t working, it may not be 
compatible with the IEEE 802.3 Type 10Base-T or IEEE 802.3u 100Base-T 
standards. The twisted-pair cables attached to the HP 10/100 hub must be 
compatible with these standards. To verify that your cable is compatible with 
these standards, use a qualified cable test device.

HP also offers a wire testing service. Contact your HP-authorized LAN dealer 
or your local HP sales office for more information.

N o t e

Make sure that you are using the correct cabling type for each connection. 
The hub ports are all wired as MDI-X. For connecting end nodes and other 
MDI-type devices, use “straight-through” cable. For connecting switches, 
other hubs, and other MDI-X devices, use “crossover” cable; or, you can use a 
straight-through cable by connecting the MDI-X device to Port 1 and change 
the port setting to MDI by depressing the MDI-X/MDI button on the front of 
the hub to the MDI position. See Appendix B, “Cables and Connectors” for the 
pinouts for straight-through and crossover cables.
