Notes about upgrading the Sentry K300:

  • This upgrade is a dual-bank update. After it is completed, you will need to wait 5-10 seconds before the device will power on. This is normal and is not indicative of a defective device.
  • The existing firmware will remain on the device until the new firmware image is activated. This means that if the upgrade process fails, the drive can still be rebooted using the previous firmware version.
  • If you are wanting to update for SafeConsole, you can review the K300 SafeConsole Deployment Guide: https://media.datalocker.com/manuals/sentry/K300_SafeConsole_Deployment_Guide.pdf
