While in operation the Luna Backup HSM will monitor the card input voltage, temperature, and battery
state.
The Luna Backup HSM monitors input voltage to the CCA. The upper voltage limit is 12.7V. All on-board
voltages are derived from the 12V input.
The Luna Backup HSM monitors the operating temperature of the assembly. Temperature excursions
outside the 0 degrees Celsius to 60 degrees Celsius range are signaled as an exception to both the CPU
and the SafeXcel 3120.
In the event that both power and the battery are removed, the Luna Backup HSM will zeroize the SafeXcel
3120 NVRAM.
