Fault description:

Previous ROM version is: s3600v2_e - cmw520 - r2101, download the latest s3600v2_e - cmw520 - R2112P04,

Did restore factory Settings first, then brush the new ROM, check the startup information in the console interface, are normal,

Set the vlan, 47 192.168.47.1 virtual interface, the admin account password and access, after open IP HTTP, in the browser open 192.168.47.1, found the login address change, turned to http://192.168.47.1/web/device/login? Lang=1, but can't open the login interface,

In the console interface to view, and I realize there's tip: admin failed to login from the Web, "reason is 3

Then switch back to the previous ROM, everything is back to normal,
