    Interpret the LEDs on a PA-800 Series Firewall

    LEDDescription
    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.
    See PA-800 Series Environmental Specifications for the temperature range.
    Ethernet port LEDs
    Left LED—Solid green indicates a network link.
    Right LED—Blinking green indicates network activity.
    SFP and SFP+ LEDsThese ports have one green LED:
    • Solid green indicates a network link.
    • Blinking green indicates network activity.
    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.
