Hi,
I have teh same switch with the same protocol, but with an even older firmware version (4.00.12), when I try to update to the newest firmware (DGS-1224T_D2_4.21.02.hex) I get the following error:
"firmware is illegal. Wrong product!"
I don't know if I need to update to earlier firmwares prior to updating to the newest?
If so, then I have downloaded the firmware 4.10.02, the zip contains 3 different files:
* 1224TFWN.hex
* 1224TFWU.hex
* 1224Tldr.hex
which of these shall use for trying to update my switch?
I have a problem loading a backup. When I create a backup using the option 'Backup settings to file' I can create a backup file. Then, when I try to load this file using 'Restore saved settings from file (config.bin)' I get the error 'Invalid file signature'.
Device Type DGS-1224T
Firmware Version 4.10.02
Protocol Version 2.001.003
I would apreciate any help.
Thanks,
