Figure 1: JCS1200 Alarm
Panel Module LEDs and Connectors

The JCS1200 alarm
panel module consists of the following components:
- Serial
connector—This DB-60 connector provides direct access to the
serial ports on each of the 12 Routing Engine bays. Use this connector
to attach the optional serial port breakout cable and connect up to
12 local consoles.
- Telco alarm connector—The alarm panel module provides
one DB-15 connector (male) for critical, major, and minor telco alarms.
Each of the alarms has a relay that enables multiple system alarm
indicators to be daisy-chained together.
- LEDs—The alarm panel module contains seven LEDs. Table 1 describes the
function of each LED.
