Keywords:
The gateway’s cryptographic module defines three Error States which may be entered due to hard or soft operational failures. Upon entering an Error State, the System CPU and ALM LED lamps will indicate the type of failure by providing a unique pattern of flashing and/or steadily lit lamps on the LEDS of the gateway’s faceplate. Additionally, G450 Branch Gateway has a serial console port that allows one to view status and error states using a monitor.

Error State 1

Error State 1 processes hard errors due to failures of the Module’s Power-up Self-Tests. Exit is via operator selection of reboot or zeroization with reboot.
LED flash patterns:
  • MDM: continuous ON 15 seconds, OFF 15 seconds
  • ALM: continuous ON-OFF flash
  • CPU: continuous cycles of two ON-OFF flashes separated by 2.25s OFF
  • PWR: on if all power supplies are healthy, flashing otherwise

Error State 2

Error State 2 processes soft errors related to conditional self-test failures. Exit is through automatic reboot.
LED flash patterns:
  • MDM: on
  • ALM: continuous on-off flash
  • CPU: continuous cycles of three on-off flashes
  • PWR: on if all power supplies are healthy, flashing otherwise

Error State 3

Error State 3 processes hard errors linked to critical function failures. Exit is automatic with immediate zeroization.
LED flash patterns:
  • MDM: on
  • ALM: continuous on-off flashes
  • CPU: continuous cycles of four on-off flashes
  • PWR: on if all power supplies are healthy, flashing otherwise
