Interpret the LEDs on a PA-220 Firewall

The following table describes how to interpret the status LEDs on the PA-220 firewall.

Front Panel LEDs
HA (High Availability)
STAT (Status)
ALM (Alarm)
TEMP (Temperature)
PWR (Power)
Ethernet port LEDs
Back Panel LEDs
PWR 1 and PWR 2

PA-220 NEXT-GEN FIREWALL HARDWARE REFERENCE | Service the PA-220 Firewall Hardware
Description
• 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).
• 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 tolerance levels).
• Left LED—Solid green indicates a network link.
• Right LED—Blinking green indicates network activity.
If you configure the link state to down on a port, the LEDs on
some active 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.
