Chassis LEDs

The chassis LEDs shown in Figure 2-2provide information about the router’s operational status. These LEDs include the input power LED, heartbeat LED, and the system fault LED. To apply power to the router, plug the power cord into the router AC power receptacle and into a 100-240 VAC power source.

Figure 2-2 Chassis LEDs

Heartbeat LED (Green)

The heartbeat LED blinks once a second as long the router firmware is operational.

Input Power LED (Green)

The power LED shows the voltage status at the router logic circuit board. During normal operation, this LED lights up to show that the router logic circuit board is receiving the DC voltage from the power supply.

System Fault LED (Amber)

The system fault LED lights up to show that a fault exists in the router firmware or hardware. Fault conditions include POST errors and over-temperature conditions. The LED shows a blink code for POST errors and the over temperature condition. See Figure 2-2and Table 2-1.
