Power supply for WIZnet Serial-to-Ethernet (question)

Hi:

I have the WIZnet Serial-to-Ethernet Gateway - WIZ110SR .

I read that the input voltage is 5 volts.

But my power suply is about 5.5 , even a little more.

Do you know if the WIZnet Serial-to-Ethernet module could work with

6 volts.

Thanks, Joe
