Hot-Swap LED
After system shutdown or if the system is in S4 or in S5 state, the hot swap LED
lights continuously.
If the system is plugged into the system slot and in S0 state or in S3 state, the board
controller ignores the hot swap switch.
If the hot swap switch is closed while the hot swap sequence is in progress, the
board controller stops flashing the hot swap LED and no longer waits for system
shutdown. If the hot swap switch is closed after system shutdown, the board
controller initiates Power Resume.
If the hot swap switch is open during power-up, the board controller delays the
power-up sequence and lights the hot swap LED until the hot swap switch is closed.

User LEDs
The user LEDs can be switched on and off using the MEN driver for the board
controller. See MEN’s
website
