Light-Guided Diagnostics
The server boards have several on-board diagnostic LEDs to assist in troubleshooting board-
level issues. This section provides a description, location and function of each LED on the
server board. For a more detailed description of what drives the diagnostic LED operation, see
the Intel
®
S5000 Server Board Family Datasheet.
7.1 5-Volt Standby LED
Several server management features of this server board require that a 5-V standby 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 ESB2-E, on-board NICs, and
optional Intel
®
RMM connector when the Intel
®
RMM is installed.
The LED is located just to the right of the CMOS battery in the center of the server board and is
labeled “5VSB_LED”. It is illuminated when AC power is applied to the platform and 5-V standby
voltage is supplied to the server board by the power supply.
