Using the system status display to monitor system hardware

A line of 10 LEDs display on the face of the Business Communications Manager (see Figure 63).

The LEDs show the current state of various hardware components. The Unified Manager contains

a monitoring tool that allows you to determine the current condition of the LEDs from your

computer. Refer to the Business Communications Manager Installation Guide for further

information.

The system status LEDs indicate monitoring of the following:

• Power status (LED 1): 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.

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

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

blink indicates one or more telephony services are not operational.

• PCI device monitoring (LED 4-8): 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 (LAN1)

— LED 8: Monitors the NIC 2 (LAN2)

• Chassis/CPU temperature (LED 9): 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.

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

more) fan is not operating correctly.

Note: If your Power or Fan LEDs are red:

If you have a BCM400 or BCM200 that does not have redundant power supplies or fans,

you may notice that the Power and Fan LEDs are red even though the power module and

fan appear to be working. Check to see if the jumper was installed across pins 2 & 3 on the

PSU Status header, which is located on the interface card near the power supply connector.

For Redundant systems this header is populated with a cable from the power supply. Refer

to the Installation and Maintenance Guide for details.

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