Interpret the LEDs on a PA-220 Firewall

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.
LEDDescription
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.
In 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).
STAT (Status)
  • Green—The firewall is operating normally.
  • Yellow—The firewall is booting.
ALM (Alarm)
  • 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.
TEMP (Temperature)
  • Green—The firewall temperature is normal.
  • Yellow—The firewall temperature is outside tolerance levels.
PWR (Power)
  • 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 tolerance levels).
Ethernet port LEDs
  • Left LED—Solid green indicates a network link.
  • Right LED—Blinking green indicates network activity.
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.
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.
