2. Verify the Hub Passes Its Self Test
Before mounting the hub in its network location, you should first verify that
it is working properly by plugging it into a power source and verifying that it
passes its self test.
N o t e
The HP 10/100 hubs do not have a power switch. They are powered on when
the power cord is connected to the hub and to a power source.
Connect the power cord supplied with the hub to the power connector on
the back of the hub, and then into a properly grounded electrical outlet.
Connect power cord
to power connector
Check the LEDs on the hub.
Hub Port LEDs
Power and Fault LEDs
When the hub is powered on, it performs its diagnostic self test. The self-
test takes approximately three seconds to complete for the Hub 12 and
Hub 24, and approximately 30 seconds for the Hub 12M and Hub 24M.
During the self test: Initially, all the hub and port LEDs are on. After
approximately three seconds, the "100" LEDs for all the ports, and the
Activity and Collision LEDs go off.
When the self test completes successfully:
The Power LED stays on.
The Fault LED goes off.
The port LEDs and Act and Col LEDs go into their normal operational
