8.3. Power Consumption during Security Erase
Typical power consumption during Security Erase depends on both the device capacity and the
NAND flash type.
The FFD input voltage is +5VDC, with a tolerance of ± 0.5V.

8.4. LED Indicator During Erase
While the FFD is running the Security Erase process, an LED blinks according to specific
patterns to indicate process status and completion, as follows:
•
The LED blinks red while a Security Erase is in progress.
•
The LED blinks green four times when the Security Erase process is complete.
•
If the Security Erase command includes the Fill option, the LED blinks alternating red and
green while the media is being filled.
•
The LED illuminates steady green while remounting the media.
