48 | Terminal Management
3 Click the Submit button to begin the re-imaging process.
The terminal will reboot and begin re-imaging its flash media with the selected
image. This re-imaging process may take 20-40 minutes, depending on the size
of the image and network traffic. During this time, there is no agent to heartbeat
into the Echo server, and therefore the timestamp in the Last Contact field will
remain unchanged. Once the re-image is complete and the terminal does its
final reboot, the agent will heartbeat into the server, which in turn will update the
Last Contact field. This update to the current time in the Last Contact field is
your cue that the re-imaging process is complete.
