System LEDs (Installation)

System Status LED

The PARTNER Messaging module faceplate contains one tri-color System Status LED. The System Status LED displays up to seven states—red, green, or amber on; red, green, or amber blinking; or unlit (off).

The table below provides a description of the System Status LED display variations.

	The LED appears red when the system is first powered up, there is a self-test failure, or is out-of-service (unable to load).
	The LED blinks alternately red and green when system software is being upgraded.
