Hi!
I have 3 units of DGS-1510 around the office. The problem is, that for some magic reason, the web interface does not want to work on them. I did enable it using the manuals, save config, and it works. But after a few days/weeks, the Web UI shows the login screen and then it is it. Nothing more happens.
I've bought all 3 of them in different periods of time. These are located in different parts of the office, so it's not like these got broken by some accident.
What I do have configured there:
* static management IP
* some simple VLANs
* NTP-simple client
and that is it, nothing fancy.
Telnet works on all of them, I can ping the interfaces, but web fails. I did not configure any special vlan for the management interface.
Reboot over telnet does not seem to bring it back. Pulling the plug seems to do the trick.
Did I configure something wrong? What might be the cause of this strange behaviour?
HP switches UIs in the same network work OK.
