Juniper Networks J2320 manual Status LED, Alarm LED

J2320, J2350, J4350, and J6350 Services Router Getting Started Guide

STATUS LED

When the system is powered on, the STATUS LED changes from off to blinking green. Startup takes approximately 90 seconds to complete. If you want to turn the system off and on again, we recommend waiting a few seconds between shutting it down and powering it back up. Table 13 on page 34 describes the STATUS LED.

Table 13: STATUS LED

Color	State	Description
Green	Blinking	Router is starting up or performing diagnostics.
	On steadily	Router is operating normally.
Red	Blinking	Error has been detected.

ALARM LED

The ALARM LED lights yellow to indicate a minor condition that requires monitoring or maintenance and lights red to indicate a major condition that can result in a system shutdown. When the condition is corrected, the light turns off. Table 14 on page 34 describes the ALARM LED.

Table 14: ALARM LED

Color	State	Description
Red	On steadily	Major alarm indicates a critical situation on the router that
		has resulted from one of the following conditions. A red
		alarm condition requires immediate action:
		■ One or more hardware components have failed.
		■ One or more hardware components have exceeded
		temperature thresholds.
		■ An alarm condition configured on an interface has
		triggered a critical warning.
Yellow	On steadily	Minor alarm condition requires monitoring or maintenance:
		■ Indicates a noncritical condition on the router that, if
		left unchecked, might cause an interruption in service
		or degradation in performance.
		■ A missing rescue configuration or software license
		generates a yellow system alarm.
Unlit	Off	No alarms.
