H100/H200 LED's
Solid green:
Open, if no authentication mechanisms are set, any user can use the device. User has logged into the device—if users exist, it indicates that the device has authenticated a user.
Flashing green:
The flash frequency is approximately once per second and indicates that the device is waiting for a finger due to one of the following situations (H200 Only)
• The device has just been plugged in and no user is currently logged into the device.
• Software has initiated a biometric authentication or the enroll operation.
• A user has initiated a finger authentication operation for example, by touching the device when it is in the “idle” waiting for-finger state. A device will remain in an idle state for only two
minutes before the LED turns red to indicate the device is locked.
Flashing red once:
Failed fingerprint authentication attempt. The device will go back to waiting for a finger (flashing green normal) after the failed signal finishes.
Flashing LED alternating between red and green:
The device is waiting for a finger to authenticate but this is also the last chance to authenticate before biometric access is blocked. The frequency is approximately twice per second.
Flashing red:
The device is either powering up or is totally blocked. When totally blocked, no authentication methods are available to allow a user to log into the device; this indicates that the device needs
to be recycled or reset.
Solid Red:
The device is locked.
Blue LED:
Indicates a data transfer activity for all devices.
Flashing red and blue:
This indicates that a fatal internal error has occurred.
Solid Yellow:
Sufficient power from the host computer is available and the device is operating normally.
Flashing yellow (slow):
Insufficient power to operate the device. Attach both USB connectors to the host computer. If both connectors are already plugged in, and the LED continues to flash, the host computer does not meet the USB power requirements.
Flashing yellow (fast):
Power detection has timed out. Unplug all USB connections and reconnect them.
No Yellow LED
No power is detected. The device is powered off.
H300/H350 LED's
Solid Red:
The device is locked.
Flashing Blue LED:
Indicates a data transfer activity for all devices.
Solid green:
Open, if no authentication mechanisms are set, any user can use the device. User has logged into the device—if users exist, it indicates that the device has authenticated a user.
Yellow LED:
Sufficient power from the host computer is available and the device is operating normally.
No Yellow LED:
Insufficient power to operate the device. Attach both USB connectors to the host computer. If both connectors are already plugged in, and the LED continues to flash, the host computer does not meet the USB power requirements.
Solid Red/Blue/Yellow LED:
Drive has failed or has been self-destructed
