Descripon
If you configure the link state to down on a port, the LEDs on
some acve ports will not work. Similarly, if the passive link
state is set to shutdown, the HA link LEDs on the passive
device in the HA pair will not work. To ensure your LEDs
display correctly, avoid configuring link states to down or
using the shutdown passive link state unless needed for
security reasons.
The following describes the power adapter LEDs on the back of the
firewall:
• Green—The power input is receiving power.
• Off—The power input is not receiving power.
The PWR LED on the front of the firewall shows green if one
or both power adapters are connected to the back power
inputs. If both power adapters are connected and one power
adapter fails, the PWR LED on the back of the firewall turns
off and the ALM LED turns red.
