3com nj220 central config error response from device
While using the 3com central configuration manager software, I can discover 3com network jacks successfully.
When I open up the Property UI for the network jack, it gives me a "Error Response from Device" error and all 4 ports show as N/A across all fields. When it does this, I can manually click the ports and set them again (they go defaulted to disabled/half-duplex/10Mbps on each port). What is going on with my software that is causing this?
I'm also unable to load valid configuration files to blanket-reconfigure the 3com from known settings. I get "Error loading configuration file" on that screen. Please help.

Found that the problem was in the installation of the service.
There were two .exe in the installation software, one labeled setup.exe and the other "3Com IJNJ Configuration Software.exe". setup.exe is what needs to be used and it will in turn call the other. I had opened the other directly.

The default IP address of the device, depends on the status of the network where the device resides, but if the device is not connected to the network, or no DHCP server exists in the subnet where the device resides, you can get the default IP address of the device on the label on the right of the device rear panel.
the defautl password was "password" on these devices, 3Com no longer sells them but their support site has the software and manuals free to download. Downlaod the Utility software and restore the facotry defaults and simply start over. Good Luck.
Attach a terminal or PC with terminal emulation to the console port of
the switch. Use the following terminal settings:
9600 baud rate
8 data bits
No stop bit
Unplug the power cable.
Hold down the mode button while reconnecting the power cord to the switch.
You can release the mode button a second or two after the LED above port 1x
is no longer illuminated.
