I have 2 Windows 7 - 64 connected via ethernet to a TS-XEL. The Auto Power Mode is in the auto position. I understood that as long as any computer is operative and is attached to it, that the unit would stay up. However, when I reboot one of the computers it sends the TS-XEL into a sleep and reboot cycle. It doesn't happen with the other. Anyone have any ideas? Thanks.
