How do I figure out which device the system fault LED is referring to on the 8450R server?

The front panel board supports the light-emitting diodes (LED) and buttons that are accessible from the front panel. Following are the descriptions of the buttons and LEDs on the front panel board.

Reset button – Lets you reset the server if it has become non-responsive.

System fault LED – Flashes whenever the server logs a failure.

Network activity LED – Lights whenever there is activity on the network.

Hard disk activity LED – Glows green whenever a hard disk is actively reading or writing data and glows amber if a hard disk fails.

Power LED – Glows green whenever the server is turned on. The LED also flashes when the server is in sleep mode.

Sleep button – Lets you put the server into sleep mode to reduce power consumption.

Power button – Turns the server on and off.
