7. Light Guided Diagnostics
The server board has several on-board diagnostic LEDs to assist in troubleshooting board level
issues. This section shows where each LED is located and provides a high level usage
description. For a more detailed description of what drives the diagnostic LED operation, refer to

7.1 5-Volt Standby LED
Several server management features of this server board require that a 5 volt stand-by voltage
be supplied from the power supply. Some of the features and components that require this
voltage be present when the system is “Off” include the BMC within the ESB-2, onboard NICs,
and optional Intel
®
RMM.
The LED located just below the system recovery jumper block labeled “5V STBY” is illuminated
when AC power is applied to the platform and 5 Volt standby voltage is supplied to the server
board by the power supply.
