Diagnostic Tests

When a Management Module is installed, the HP AdvanceStack Assistant and

ASCII console software provide tests and indicators that can be used to

monitor the hub and its network connections. See the Management Module

manual for more information.

Testing the Hub or Stack of Hubs

If you believe that the hub is not operating correctly, you can reset the hub to

test the hub’s circuitry by removing the power cable to that hub. To reset a

stack, either:

■ Remove and reinsert the power cord for each hub.

■ Press the Reset button on an optional Management Module

■ Select Reset in HP AdvanceStack Assistant or the ASCII console

(software is provided with the HP Management Module)

A hub hardware failure was detected during self-test. Self-

test does not complete so the LEDs will stay on longer than

60 seconds.

Power cycle the hub. If this condition persists, the hub may

have to be replaced. Contact your HP-authorized LAN

dealer or HP representative for assistance.

* This LED is not important for the diagnosis.

The slow flash is approximately once every 1.5 seconds, the rapid flash is approximately three times per second.
