PS 2 status LED glows green when the second power supply module in the redundant power supply is installed and working correctly. It flashes green if the power supply module fails or one of its power levels goes out of bounds. If the power supply module is not installed, this LED is off. System reset button lets you reset the server if it has become nonresponsive. Power button turns the server on and off. In an ACPI-enabled operating system like Windows 2000, you can set the power button to enter sleep mode rather than turning the system off. Power supply alarm speaker reset/System fault LED reset switch disables the power supply alarm speaker or resets the system fault LED. The alarm is not cleared and the appropriate LED continues to glow until the failed power supply module is replaced. NMI (Non-Maskable Interrupt) button allows a technician to help debug server errors. Chassis intrusion detection switch sends a message to the system management hardware, logging an event when the front bezel is removed. Front panel connector connects the controls on the front panel with the system board. Front panel board 13
