Verifying LED Operation

Verifying LED Operation
If you suspect a non-operating LED, reset the router to verify the LEDs.
C a u t i o n
Resetting the router causes bridging and routing tables to be reset.
Verifying LED Operation on the HP Router ER,
TR, and SR
1. Press and hold the Reset button while you verify that the ~Line On
and Fault LEDs on the front of the router are lit and that the Power,
Fault, Self-test, and Net Fail LEDs on the back of the router all are lit
while you are pressing the button. (For the Router TR only, the Rx
and Insert LEDs for the token ring port will also light when you press
the Reset button.)
2. Then release the button—which begins router initialization—and
verify that the Self-test LED is lit. After the Self-test LED turns off
(in about one minute), if you have running networks connected to
the WAN and Ethernet/802.3 ports, then you should see Tx and Rx
and Activity LEDs blink for passing traffic on these ports. If all of
this happens, the LEDs are verified.
Verifying LED Operation on Other Router
Models
Use this method to verify the LEDs on HP routers other than the HP
Router ER, TR, and SR models.
Press and hold the Reset button. All LEDs should light. If any LED does
not light, either the LED or its driver circuit has failed. Normally, after
you release the Reset button, only the Power, Self-test, and
Ethernet/802.3 (AUI/BNC) connector LEDs will be lit.
