Interpret the PA-5400 Series LEDs

Learn how to interpret the status LEDs on a PA-5400 Series firewall.
The following table describes how to interpret the status LEDs on a PA-5410, PA-5420, and PA-5430 firewall.
The PA-5450 LEDs are located on the interface cards. For more information, see PA-5400 Series Firewall Module and Interface Card Information.
LED
Description
Front Panel LEDs
Service
  • Blue
    —The firewall is instructed by the CLI or Web Interface to enable this LED.
  • Off
    —The LED has not been enabled.
Power
  • Green
    —The firewall is powered on.
  • Red
    —One of the power supplies is not within tolerance levels.
  • Off
    —The firewall is not powered on.
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-5400 Series Firewall 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
    —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 (PWR 1) is on the left and power supply 2 (PWR 2) is on the right.
  • Green
    —The power supply is functioning normally.
  • Red
    —The power supply is present but is not working.
  • Off
    —The power supply is not installed
Ethernet Port LEDs
RJ-45
These ports have one green LED each.
  • Solid Green
    —The firewall network link is up.
  • Blinking Green
    —The firewall is processing network activity.
SFP, SFP+, and QSFP 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.
Back Panel LEDs
Power supply LEDs
In AC power supplies, the input LED indicates the status of the AC input power and the output LED indicates the DC output that powers the firewall. In DC power supplies, the input and output are both DC.
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.
