The system status LEDs indicate monitoring of the following:

- LED 1 (Power status): Indicates the status of all power components. Green indicates normal

status. Red indicates an excessive voltage deficiency or a component failure (such as a

redundant power supply fan or module). An LED that monitors a component will also show a

fault in combination with the Power LED.

- LED 2 (Hard disk activity): Green indicates hard disk access.

- LED 3 (System status): Solid green indicates the system is normal and operational. Green

blink indicates one or more telephony services are not operational.1

1 Six, non-blinking LEDs in the center indicates monitoring software is not active.

- LED 4-8 (PCI device monitoring): These LEDs monitor the peripheral components (2 x NICs,

1 x WAN, 1 x Modem, 1 x MSC). A steady green LED indicates the device is detected and

operationally normal. A flashing green LED indicates that software detects the hardware, but

there is no device driver. No color indicates the device is defective or missing.

- LED 4: Monitors the MSC

- LED 5: Monitors the WAN (if installed)

- LED 6: Monitors the modem (if installed)

- LED 7: Monitors the NIC 1

- LED 8: Monitors the NIC 2

- LED 9 (Chassis/CPU temperature): Green indicates a normal, operational temperature range

for the chassis. Red indicates either a sensor is not operational or the chassis temperature is out

of range.

- LED 10 (Fan activity): Green indicates that all fans are operational. Red indicates that one (or

more) fan is not operating correctly.

- Reset button: The reset button when depressed, restarts the system. The reset button is

recessed to prevent an accidental reboot.
