Luna PCIe HSM 7 Onboard LEDs

In normal operation the HSM card is inside a host computer's sealed enclosure and not visible, but if you have it running while exposed, the four LEDs near the fan-power sockets are as follows:

D1	Indicates that a tamper occurred and has not been reset	Red	On if a tamper event is detected and not yet acknowledged/cleared. Off during normal HSM operation.
D2	GPIO01 startup Thales debug	Green	Reserved for Thales use.
D3	GPIO00 boot progress Thales debug	Blue	Reserved for Thales use.
D4	Alternate battery source	Green	Indicates that an alternate battery has been detected and replacement of the onboard battery can proceed. Off during normal HSM operation.
