Diagnostic Mode Removable Media / Fixed Disk Toggling
The keypad has a manual diagnostic mode built-in to verify proper keypad
function and troubleshooting key issues. This mode will not allow access to
any data or admin function. It can only be used to identify the rmware level
and to test button recognition.
To enter the diagnostic function:
1. Press , then press LOCK + 1, release, then press and continue to hold
the 0 button as the RED and BLUE LEDs blink alternately. Once all
three LEDs illuminate solidly, release the 0 button.
2. The BLUE LED will blink a number of times to represent the number of both
the major and minor revisions. The decimal point will be represented by a
single RED LED blink. Upon completion, the BLUE LED will glow solidly.
(Example: VERSION 4.1 would be indicated by four BLUE LED blinks, one
RED LED blink, one BLUE LED blink, and one RED LED blink, then revert
to the BLUE LED glowing solidly.)
3. To check the keypad’s button functionality, press each button and the
number of the button pressed will be expressed by the RED LED blinking.
(Example: 1 Button= 1 blink, 2 Button = 2 blinks, 3 Button = 3 blinks...0
Button = 10 blinks, Button = 11 blinks, Button = 12 blinks.)
4. To exit the Diagnostic Mode, wait for the 20 second timeout or hold the
Lock Button for ~7 seconds to return the key to its normal operation.
Self-Diagnostics:
During the initial power up, after the key has been plugged into a USB port,
the key will perform self-diagnostics on the encryption algorithm and critical
hardware components. If the RED LED blinks at a rate of one blink per
second for 15 seconds, returns to standby and will not unlock, unplug the
key from USB port and try again. If the RED LED continues to blink in the
manner mentioned above and won’t unlock upon USB re-insertion, a critical
component has failed and the key can no longer function.
If the key blinks a triple-RED LED pattern that is repeated every two
seconds when unlocked, a failure has occurred that will not immediately
stop the device from working nor affect the security of the device, but
should be considered as a warning that the device needs to be replaced in
the near future. Additionally, Admin features may be limited in this mode.
If either condition should appear, remove the key from the USB port and
allow the key to go to sleep, and try to unlock the key again. The event of
either diagnostic failure will be very rare, but if the key cannot recover, it
must be replaced.
Two devices in one: Windows, Mac, and Linux all deal with Mass Storage
devices differently depending on whether they report themselves to the host
as Removable Media or as Fixed Disks. Some applications or embedded
systems may allow one type but not the other. Example: Windows 2 Go will
work with devices that report as Fixed Disk but not as Removable Media.
Alternately, there are USB boot drive creators and Windows imaging tools
that will only work with Removable Media and not with Fixed Disk. It’s not
uncommon for older equipment with built-in USB ports (such as those found
in hospitals, manufacturing, and monitoring) to only look for Removable
Media and ignore any Fixed Disk that is attached.
To accommodate all situations, Apricorn has developed a means to allow the
Secure Key 3NX to be congured as either Fixed Disk or Removable Media.
By default, the drive is set as Removable Media but can be easily changed
to Fixed Disk in the Admin mode and can be toggled between these modes
as needed. (The default boot record is set to MBR; If you need to set the
drive as Fixed Disk and use a GPT boot record, either reset the drive or use
a tool like Diskpart to clean the drive to allow a new boot record and format
to be applied.)
To enter the diagnostic function:
1. Enter the Admin mode. (Press and hold + 0 for ve seconds – while
the RED LED is blinking, enter the Admin PIN and press the button.)
The BLUE LED will glow solidly, then perform one of the following:
2. FIXED DISK MODE: Press the 3 + 2 buttons together. The GREEN
LED will blink to indicate the command was accepted.
3. REMOVABLE MEDIA MODE: Press the 7 + 3 buttons together. The
GREEN LED will blink to indicate the command was accepted.
4. Drive will return to the Admin Mode, indicated by a solid BLUE LED.
5. Press the LOCK button to return the device to standby mode.
