10. Light Guided Diagnostics

The server board includes several on-board LED indicators to aid troubleshooting various board
level faults. This section provides a description of the location and function of each LED on the
server boards.

10.1 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.
