| Front Panel LEDs |
| 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). |
| FANS | Green—All cooling fans are operational. Off—One
or more fans failed. |
| ALARM | Red—A hardware component failed, such as
a power supply 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. |
| STATUS | Green—The firewall is operating normally. Yellow—The
firewall is booting. |
| 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 indicates only 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). |
| TEMP (Temperature) | Green—The firewall temperature is normal. Yellow—The
firewall temperature is outside tolerance levels. |
| Ethernet port LEDs | Left LED—Solid green indicates a network
link. Right LED—Blinking green indicates network activity. |
| SFP and SFP+ LEDs | These ports have one green LED: |
| Back Panel LEDs |
| (PA-850 firewall only) Power supply LED | Green—The power supply is operating normally. Off—The
system detected a loss of power, either due to loss of power connection,
a failed power supply, or incorrect input voltage. If this occurs,
the front panel PWR and ALARM LEDs turn red. |
