Front panel connector connects the controls on the front panel with the system board.

Power LED glows green whenever the system is turned on. The LED also flashes when the system is in sleep mode.

Network activity LED lights whenever there is activity on the network.

System fault LED flashes whenever the system logs a failure.

Disk activity LEDs glow green whenever the hard disk is actively reading or writing data and glow amber if the disk fails.

Backplane connector carries signals from the hot-plug backplane to the control panel.

NMI switch allows a technician servicing the server to generate a non-maskable interrupt (NMI) to help debug server errors.

Reset button lets you reset the server if it has become nonresponsive.

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

Power button turns the server on and off.
