Please be aware that upgrading EZSrve via Firefox while using a fixed (static) IP leads to corruption of the EZSrve. We are currently investigating this situation and hope to have recovery and prevention steps in place in a few days.
Until then, please avoid Firefox for upgrading through the web interface.
Also, even with IE, please restore the module to DHCP, and clear the flash by doing a “Reset” through the web interfce. The upgrade will be much smoother.
In the event this happens, please refer to the TFTP recovery procedure posted as a sticky item below.
