Sub Description
category
— The system status LED indicates the combined status of the router's
three main functional blocks (the control and switching functional
block, the T1/E1 ports functional block, and the Ethernet ports
functional block). Blocks that are administratively shut down are not
included in the combined status indicated by this LED.
Green (solid): Indicates that the system is operationally up, which
means that all functional blocks configured to be administratively up
are operationally up
Green (blinking): Indicates that one or more functional blocks is
initializing
Amber: Indicates that one or more functional blocks is operationally
down but administratively up, or that hardware is booting up
Unlit: Indicates that there is no power getting to the system
— The Audible Alarm Cutoff/Lamp Test button verifies LED operation
and turns off the external alarm control bits.
When pressed: The Lamp Test is enabled and the following LED
activity occurs:
• the status LED on the chassis glows green
• all T1/E1 port LEDs glow green
• critical and major Alarm LEDs glow red and the minor Alarm LED
glows amber
Note: The following LEDS are not affected by the Lamp Test:
Management port LEDs, Battery A/B LEDs, and all Ethernet port
LEDs.
When released: All LEDs except the Alarm LEDs return to their pre-
Lamp Test state. The Alarm LEDs turn off and stay unlit until the next
new alarm condition.
Connector The External Alarms port is a serial port that uses a DB15 female
connector. It can receive input signals from four external alarm devices
and provide output signals through three sets of contacts. Refer to
