Can't Access GS1900-24HP After Firmware Upgrade on the Network

zyxeluser100

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?

Ha! thanks, that found it. Seems so obviously after the fact.

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

Hi @zyxeluser100,

You also can use ZON to find your device.
