Never mind, looks like it was an issue with IE on the computer I was using. I incidentally tried connecting to a PC2848 and I got the same error but I know I was able to connect using other computers without any problem. I installed Chrome and it worked.  Yet again IE lax / wrong web standards strike again. Thanks for your help.
When I upgrade this old switch to any FW version over 1.0.1.13 (2.0.x+) I receive this error when I try to go to the web admin page: "Access error: request entity too large"  and I get this in the console: "GOAHEADG: received illegal length ..."  I've tried many of the FW version 2.0.X and I've even tried both ways to copy the file, XModem and TFTP, but they all end the same error. All I do is downgrade to the 1.0.1.13 FW and all is fine. Am I missing something? I guess we really don't need the new FW as we haven't experienced any issues with these switches, but I was wanting to get us to the latest version since we've been outdated for quite some time.  Any advice? Thanks in advance.
