Light Guided Diagnostics
Both server boards have several onboard diagnostic LEDs to assist in troubleshooting board-
level issues. This section provides a description of the location and function of each LED on the
server boards.
9.1 5-volt Stand-by LED
Several server management features of these server boards require a 5-V stand-by voltage
supplied from the power supply. The features and components that require this voltage must be
present when the system is powered-down. The LED is illuminated when AC power is applied to
the platform and 5-V stand-by voltage is supplied to the server board by the power supply.
