I just updated to the latest firmware on a GS1900-24HP that I purchased in 2015. After resetting, the admin credentials would not authenticate and I could not login. The release notes mentioned an algorithm change, so I reset the switch (Held down the button on the front 10 seconds and the unit power cycled). Now, the switch does not come up a network as 192.168.1.1 on the network. I've reset it 3 or 4 times now, and no dice. The switch still functions as a switch, but it won't come on the network as 192.168.1.1. Is there any recourse? It doesn't look like this model has a COM port.

    Did you look for a "not expected" IP address on your DHCP server?

    It was one of the options, the Switch did not keep up the configured Ip and went into DHCP mode... :-)
