The MPCBL0001 SBC supports one bicolor health LED to indicate the SBC’s health status, i.e., 
whether a fault or error condition has been detected on the SBC. This LED is mounted on the front 
faceplate and driven by the onboard IPMC. The health LED will only be driven to an error 
condition (red) if there is a critical or non-recoverable (major or critical in AdvancedTCA 
parlance) condition active on the SBC. Alarms could include exceeding sensor thresholds for 
temperature and on-board logic voltages. The health LED remains red until the sensors return to a 
normal operating value. Hard-drive failures, boot failures, etc. are not considered critical/major 
IPMI states, so the IPMC does not explicitly set the health LED in these cases.

The LED's error state color defaults to red, but the color can be overridden. using PICMG 3.0-
defined commands. Refer to 

 

The default color and override capabilities of the LED follow the LED management requirements

The MPCBL0001 SBC supports one bicolor “OOS” LED, mounted on the front faceplate. The 
LED can be driven to display a red or amber color. When this LED is lit, it indicates that the board 
is not in service. Its back-end (payload) power could be OFF or ON. Often the OOS state is entered 
when a critical fault occurs on the board. In this state, the back-end (payload) power is turned OFF. 
A board could be in this state when its back-end power is OFF but healthy, or when a board is fully 
powered but not yet deployed, or during the reset process.

Do not extract a board unless the Hot Swap LED is lit.
