Only one of the two firmware versions stored in the device can be active at any time. When new firmware is uploaded, the currently inactive firmware version will be overwritten. The firmsafe mode lets you decide which firmware is to be activated after the upload.
Possible values:
- Immediate: This option allows you to upload the new firmware and activate it immediately. The following situations can arise: The new firmware is uploaded successfully and it then becomes active as desired. Everything is OK. After uploading the firmware the device no longer responds. If an error occurred during the upload, the device will automatically activate the previous firmware and will restart.
- Login: To respond to the problems of a faulty upload, there is a second option to upload and immediately activate the firmware. In contrast to the first variant, the device then waits for firmsafe timeout while waiting for a successful login via telnet, a terminal program or WEBconfig. Only after this login is the firmware activated. If the device stops responding or it is not possible to login, then the old firmware is activated automatically and the device starts again.
- Manually: The third option allows you set a time period in which you can test the new firmware. The device starts with the new firmware and waits for the set time period for the uploaded firmware to be activated manually, in which case it will be activated permanently. Under LANconfig you activate the new firmware with Device > Firmware management > Release tested firmware, under telnet under 'Firmware/Firmsafe-Table' with the command 'set # active', where # is the position of the firmware in the firmsafe table. Under WEBconfig you will find the firmsafe table under Firmware in the Expert configuration.
Default:
- Immediate
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.
