System Reset Button and LED Behavior
Pressing the reset button will turn on all of the LEDs in the system. If you
initiate a hard reset (pressing the reset button for 3 seconds or longer) all of
the LEDs will flash simultaneously to acknowledge that a reset to factory
defaults has been initiated.
If the 5160 system was in a non-responsive state when the reset button was
depressed, the following LED indications will occur after the reset button is
released:
• the port LEDs will count down while the state dump is in progress. The
count down will start with all port LEDs on, and will turn off LEDs in
sequence until they are all off. This sequence will repeat until the state-
dump has completed.
• when the system reboots, the LEDs proceed through the normal startup
behavior with the STAT LED blinking green until the system has initialized.
