The firmware-upload mode is set in the Setup menu under . Three different modes are available. LANconfig provides the options for uploading firmware upload either as an 'immediate' process by 'manual' means (cf. Firmware upload via LANconfig).
- Immediate: This option loads the new firmware and activates it immediately. The following situations can result:
- The startup with the new firmware is successful and the device then operates as intended.
- After uploading the firmware the device no longer responds. If the device does not automatically fall back to a previous firmware or if it starts with a minimal firmware, you can repeat the upload, for example via LL2M. If an error occurs during the upload, the device automatically activates the previous firmware and restarts.
- Login: In this mode, the device only activates the uploaded firmware temporarily in order to prevent problems from a failed upload. After activation, the device waits for a successful login via a terminal program or WEBconfig for the time (in seconds) set in the Setup menu under . Only after this login is the firmware activated.If the device no longer responds or it is impossible to log in, it automatically loads the previous firmware version and reboots the device with it.
- Manual: In this mode, the device only activates the uploaded firmware temporarily in order to prevent problems from a failed upload. The device starts with the new firmware and waits for the time period set under until the loaded firmware is manually activated and therefore becomes permanently effective.Using LANconfig, activate the new firmware with the menu item . In the Setup menu, you activate the firmware under . Using the CLI, enter the command line set # active, where '#' stands for the position of the firmware in the FirmSafe table. In this case, too, after the timeout has elapsed the device automatically switches back to the previous firmware and restarts.
Important: It is only possible to upload a second firmware if the device has sufficient memory available for two complete firmware versions. Up-to-date firmware versions (with additional software options, if applicable) may take up more than half of the available memory in older hardware models. In this case these device uses the asymmetric Firmsafe.
