Thank you for the quick reply. I am in the US, this is a USED switch and here is the info from the stickers and what the web interface is telling me:
Stickers
----------
Type: DGS-1210-52
H/W: C1
F/W: 4.10.004
Web UI
---------
Type: DGS-1210-28P
Boot Ver: 1.00.016
Firmware: 4.00.064
Hardware: C1
Serial Number: Different than sticker. Refurb?
MAC: Different than sticker. Refurb?
The firmware for the 1210-52 HW C from D-Link is 4.10.004, which is different than what is installed. I tried installing it, anyway, but the Web UI would not let me. I also tried via the CLI, to no avail.
I have setup a TFTP server and will see if there is a way I can use the CLI to force the installation of the downloaded firmware. Any other ideas?
