TL-SG3424P CLI blank screen
Hi,
Our customer has 8 TL-SG3424P switches and 7 of them show a blank screen when using the CLI.
If you log in via a console cable, you'll get a blank screen right away. If you log in using SSH, you'll be prompted for your credentials (which are definitely checked as you will get a notification if you get them wrong) and once you enter the username and password correctly, you'll then again get a blank screen, no prompt, no reaction to any input.
All the switches are the same model and use the same firmware. We tried rebooting one of them, but that didn't help.
The web interface seems to work fine on all of them.
Only one of the switches of this model has a working CLI. There are no config differences between the working switch and the faulty ones if you exclude regular stuff like IP addresses, VLAN assignment and similar. The access and admin configs are the same. Switches that are of different models have a CLI that works fine.
I've already opened a ticket with support regarding this, but figured I could also ask here to see if anyone has any knowledge about the issue. Any help is appreciated.
Thanks,
Momcilo
