Led Behavior - HP ProCurve 1600M Installation Manual

Self Test LED
Power and Fault LEDs
When the switch is powered on, it performs its diagnostic self test. The
self test takes approximately 45 seconds to complete.

LED Behavior:

During the self test:
• Initially, all the switch and port LEDs are on.
• After approximately 3 seconds most of the LEDs go off and then may
come on again during phases of the self test. For the duration of the
self test, the Self Test LED stays on.
When the self test completes successfully:
The Power LED remains on.
•
For the Switch 1600M, the Fan Status LED also stays on.
•
• For a switch in which a module is installed, the Module Status LED
also stays on.
The Fault and Self Test LEDs go off.
•
• The port LEDs on the front of the switch and on the switch module
go into their normal operational mode:
–
–
If the LED display is different than what is described above, especially if
the Fault and Self Test LEDs stay on for more than 60 seconds or they
start blinking, the self test has not completed correctly. Refer to chapter
3, "Troubleshooting" for diagnostic help.
If the ports are connected to active network devices, the Link
LEDs stay on and the Mode LEDs behave according to the mode
selected. In the default mode (Activity), the Mode LEDs should
flicker showing network activity on the port.
If the ports are not connected to active network devices, the Link
and Mode LEDs will stay off.
