Shutdown operations
To initiate a shutdown press and hold the Shutdown button on the enclosure. When the controller detects that the Shutdown button is being
pressed, it enters the shutdown mode. This is indicated by the Backup LED flashing the alert mode pattern (On 100-mS, Off 100-mS).
To verify the Shutdown button is functioning and not in a failed state, the controller must detect the button release before proceeding. Once
the button is released, the controller puts the software in a safe state. During this process, the Backup LED toggles with the work pattern (On
1-Second, Off 1-Second). Once the software has successfully completed its process, it notifies the controller that it is safe to shutdown. The
controller turns off the Backup LED indicating it is safe to remove power.
In the event that the software is unable to put the system into a safe state, the software notifies the controller that it could not complete
the request. The controller then indicates this by toggling the Backup LED with the error pattern (On 200-mS, Off 200-mS, On 200 mS, Off
3-Seconds).
Shutting down the controller
The shutdown procedure allows you to safely shutdown the controller.
1. Press and hold the Shutdown button until the Backup LED begins to flash.
In QNX 4.3, the heartbeat LED also turns off, and all Ethernet, USB, and console connectivity is lost.
2. Once the Backup LED begins to flash, release the Shutdown button.
3. Once the Backup LED turns on (solid) and begins to blink, wait until the Backup LED turns off.
4. Remove power to the controller.
Note:
If you have a terminal connected to the controller, the following message displays when the shutdown process is complete and it is safe to
remove power.
iomonitor: shutdown complete, safe to remove power
