Interpret the PA-3400 Series Status LEDs

Learn how to interpret the status LEDs on a PA-3400 Series firewall.
The following table describes how to interpret the status LEDs on a PA-3400 Series firewall.
LED
Description
Front Panel LEDs
Service
  • Off
    —The firewall is operating normally.
  • Blue
    —The firewall is instructed by the CLI or Web Interface to enable this LED.
Power
  • Green
    —The firewall is powered on.
  • Off
    —The firewall is not powered on or an error occurred with the internal power system (for example, power is not within tolerance levels).
Status
  • Green
    —The firewall is operating normally.
  • Yellow
    —The firewall is booting.
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).
Temperature
  • Green
    —The firewall temperature is normal.
  • Yellow
    —The firewall temperature is outside tolerance levels.
See the PA-3400 Series Environmental Specifications for the operating temperature range.
Alarm
  • Red
    —A hardware failure, such as a power supply failure, a firewall failure that caused an HA failover, a drive failure, or the hardware overheated and exceeded the high temperature threshold.
  • Off
    —The firewall is operating normally.
Fans
  • Green
    —The fan tray and all fans are operating normally.
  • Red
    —A fan failed. If one of the three fans fail, the firewall will continue to operate but if two fans fail, the firewall will shut down.
Power Supplies 1 and 2
When facing the back of the firewall, power supply 1 (PS 1) is on the left and power supply 2 (PS 2) is on the right.
  • Green
    —The power supply is operating normally.
  • Red
    —The power supply is present but is not working.
Ethernet Port LEDs
RJ-45
These ports have two green LEDs each.
  • Solid Green
    —The firewall network link is up.
  • Blinking Green
    —The firewall is processing network activity.
SFP, SFP+, SFP28, QSFP+ and QSFP28 LEDs
These ports have one LED each. The color of the LED will differ based on the port speed.
1G—Yellow
10G—Green
25G—Green & Blue
40G—Yellow
100G—Blue
  • Solid Color
    —The firewall network link is up.
  • Blinking Color
    —The firewall is processing network activity.
There is a slight difference in the shade of green used by the LEDs of Ports 1-22 and the LEDs of Ports 23-36.
Back Panel LEDs
Power supply LEDs
The top LED provides status of the power input and the bottom LED provides status of the power supply output.
  • Input LED (Top)
    • Solid green
      —Input voltage operating within the normal specified range.
    • Blinking green
      —Overvoltage or undervoltage warning.
    • Off
      —Exceeded the overvoltage or undervoltage threshold or no input power.
  • Output LED (Bottom)
    • Solid green
      —Main output and standby output enabled; no power supply warnings or faults.
    • Blinking green
      —Standby output enabled with no power supply warning or fault detected.
    • Blinking yellow
      —Power supply warning detected.
    • Solid yellow
      —Power supply fault detected.
Fan tray LED
  • Green
    —All fans are operating normally.
  • Red
    —A fan has failed.
