The Server Board in the Intel Server System SC5650HCBRP has 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.

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 "power-down" include the Integrated BMC, onboard NICs, and

optional Intel RMM3 installed in the Intel RMM3 slot.

The LED is located near the Intel SAS Entry RAID Module AXX4SASMOD slot in the lower-left
corner of the server boards and is labeled "5VSB_LED". It 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.
