Chassis Status LEDs

Callout	LED	Description
1	SSD0	Blinking green—The device is transferring data to or from the SSD storage device. Solid red—The SSD storage device has failed. Off—SSD storage device is not present on the device.
2	STAT	Solid green—The device is operating normally. Blinking green— The device is powered on and is in the bootup phase before OS initialization Solid red—A hardware component has failure. Off—The device is powered off.
3	PWR	Solid green—The device is powered on. Blinking green—The device is powered on and is in the bootup phase before OS initialization. Red—System power failure. Off—The device is powered off.
4	ALM	Solid red—Critical alarm Solid yellow—Non-critical alarm Off—No alarms
5	HA	Solid green—All HA links are available. Solid yellow—Some HA links are unavailable. Red—Device is inoperable due to a monitor failure. Off—HA is disabled.
6	SSD1	Blinking green—The device is transferring data to or from the SSD storage device. Solid red—The SSD storage device has failed. Off—SSD storage device is not present on the device.

Management Port LEDs

Callout	LED	Description
1	Link (LED on the left)	Solid green—A link is established. Off—No link established.
2	Activity (LED on the right)	Blinking green—There is link activity. Off—No link activity.

HA Port LEDs

Callout	LED	Description
1	Link (LED on the left)	Solid green—A link is established. Off—No link established.
2	Activity (LED on the right)	Blinking green—There is link activity. Off—No link activity.

Network Port LEDs

Each SRX4700 network port uses a single bicolored LED to indicate link status or a fault condition.

Link status LED of QSFP56-DD port 0/0
Link status LED of QSFP28 port 0/1
Link status LED of SFP56 port 0/10
Link status LED of SFP56 port 0/11

The number next to the LED indicates the port number to which the LED belongs. All network port LEDs behave the same. Table 2 describes the network port LEDs on SRX4700 Firewall, their colors and states, and the status that they indicate.

Table 2: Network Port LEDs on SRX4700 Firewall
LED Color	LED State	Description
Unlit	Off	This indicates one of the following events: Transceiver not present. The port has been disabled by the administrator.
Green	On steadily	Link is established, and there is link activity.
Amber	On steadily	Port link is down or the port encountered errors such as loss of signal, local fault, or remote fault.
Red	On steadily	The link is down because the port/transceiver has a hardware failure.
