8 ACO/LT Push
Button
— The Audible Alarm Cutoff/Lamp Test button verifies LED operation,
turns off the external alarm control bits, and controls the ADP interface
during startup.
When pressed: The Lamp Test is enabled (if ADP is not running on the
system) and the following LED activity occurs:
• the system 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: Module
LEDs, 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.
When pressed and held for 3 s while ADP is running: The ADP
interface is enabled. Refer to Automatic Discovery Protocol for a
complete list of ADP commands using the ACO/LT button.
9 Console Connector The Console port uses an RJ-45 connector and is used for the initial
system startup as well as system configuration and monitoring. The
Console port is a Universal Asynchronous Receiver/Transmitter (UART)
port. Refer to Console Port for pinout assignments.
Use an RJ-45 CAT5e cable to connect a terminal to the Console port. The
factory default baud rate is 115.2 KBaud and can be reconfigured for 9.6,
19.2, 38.4, or 57.6 KBaud.
10 Sync In The “In” synchronization port has a 1.0/2.3 coaxial connector that can be
used to receive an external synchronization input signal.
Out The “Out” synchronization port has a 1.0/2.3 coaxial connector that can
be used to provide an external synchronization output signal.
