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 (PS1) is on the right and power supply 2 (PS2) is on the left. 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	The SFP, SFP+ and SFP28 ports have two LEDs each; the LED illuminated depends on the transceiver that is installed. The QSFP+ and QSFP28 ports have four LEDs each. On the SFP/SFP+/SFP28 ports, the left LED glows yellow when a 1G transceiver is connected and the right LED glows green when a 10G transceiver is connected. When operating at 25G speed, the right LED glows teal. On the QSFP28 ports, the LEDs are illuminated based on breakout status. Breaking out the port to 10G causes all LEDs to glow green. Breaking out the port to 25G causes all LEDs to glow teal. If the port is not broken out, the LEDs glow yellow for 40G and blue for 100G. The color of the LED differs based on the port speed. 1G—Yellow 10G—Green 25G—Teal 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.
