Min Amber: A serious condition exists, such as a component failure.
If there are no minor alarm conditions, this LED should remain off.
4 BITS The BITS port is provisioned with a RJ-45 jack and used for the network
clock source.
5 DTE If the switch is flipped to DTE, the console port is acting as a data
terminal equipment (DTE) serial port.
Default: DTE, 115,200 baud, 8-bit, no parity.
DCE If the switch is flipped to DCE, the console port is acting as a data
communications equipment (DCE) serial port.
6 Console The console port is provisioned with a DB-9 jack and used for the initial
system startup as well as system configuration and monitoring. The
console port, a Universal Asynchronous Receiver/Transmitter (UART)
port, is used for system configuration and monitoring.
Use a EIA/TIA-232 DCE console cable to connect a terminal to the
console port.
Default: 115,200 baud, 8-bit, no parity.
7 AUX The UART Auxiliary (diagnostic) port is provisioned as a DB-9 serial
auxiliary port and is used for modem connection.
8 Alarm The Alarm port is provisioned as a DB-9 serial port and is used to connect
to external alarm devices that report conditions that trigger red or amber
alarms.
9 ACO/LT The Audible Alarm Cutoff/Lamp Test button verifies the operability of
LEDs. When pressed, the LEDs should temporarily illuminate. This
button also turns off all external alarm relay control bits until the next
new alarm condition.
