4.4 Powering the System

Once you’ve installed your ServSwitch USB and attached your equipment to it, you need to apply power to the Switch system. Plug the power supply’s output cord into the power jack on the back of the ServSwitch USB, then attach the input cord to the power-supply transformer’s IEC 320 inlet, then plug the input cord into utility (mains) power. The Switch should start operating immediately; it has no ON/OFF switch. Now plug in and power on your monitor and any other powered peripherals. Lastly, plug in and power on your CPUs.

Always apply power to the ServSwitch USB first, then power on the monitor and each of the computers; if you power up the computers before the Switch, the system will probably not work. In particular, some Mac computers that power up without a monitor attached either directly or through the Switch will go into a “no video” mode and will simply not output any video signal. There is no way to correct this situation; a Mac that powers up with no video must be rebooted.
