Learn to interpret the status LEDs on the PA-220 firewall.
The following table describes how to
interpret the status LEDs on the PA-220 firewall.
Front Panel LEDs
HA (High Availability)
Green—The firewall is the active peer
in an active/passive configuration.
Yellow—The firewall is the passive peer in an active/passive configuration.
Off—High availability (HA) is not operational on this firewall.
an active/active configuration, the HA LED only indicates HA status
for the local firewall and has two possible states (green or off);
it does not indicate HA connectivity of the peer. Green indicates that
the firewall is either active-primary or active-secondary and off
indicates that the firewall is in any other state (for example,
non-functional or suspended).
Green—The firewall is operating normally.
Yellow—The firewall is booting.
Red—A hardware component failed, such
as a power adapter failure, a firewall failure that caused an HA
failover, a drive failure, or hardware is overheating and the temperature
is above the high temperature threshold.
Off—The firewall is operating normally.
Green—The firewall temperature is normal.
Yellow—The firewall temperature is outside tolerance levels.
Green—The firewall is powered on.
Off—The firewall is not powered on or an error has occurred
with the internal power system (for example, power is not within
Ethernet port LEDs
Left LED—Solid green indicates a network
Right LED—Blinking green indicates network activity.
you configure the link state to
port, the LEDs on some active ports will not work. Similarly, if
the passive link state is set to
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
or using the
link state unless needed for security reasons.
Back Panel LEDs
PWR 1 and PWR 2 (Back panel LEDs)
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.
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.
