from the switch, but the switch still works fine.
KVM Switch unit draws the power source from power adapter and all PC’s PS2 port.
Some PC’s PS2 port can support enough power for the switch, but some PC’s PS2
port ( like laptop, notebook computer…etc.) is unable to supply enough power for the
switch. In order to make sure the system can work steadily, please do not set power
switch to off state or remove the power adapter from the switch.
Although the PCs connected to KVM Switch unit are able to support enough power to
the stand alone switch, KVM Switch unit still needs a power adapter for daisy chain
more banks.
