Problem with power switch and power adapter
Q: The power switch is off, but the switch still works fine or power adapter is
unplugged from the switch, but the switch still works fine?
KVM SWITCH draws the power source from power adapter and computer’s PS2 port. Some com-
puter’s PS2 port can support enough power for the switch, but some computer’s PS2 port ( like lap-
top, notebook computer…etc.) is unable to supply enough power for the switch. In order to make
sure the system can work reliably, please do not set power switch to off state or remove the power
adapter from the switch.
Although the computers connected to your KVM SWITCH are able to support enough power to the
stand alone switch, the KVM SWITCH requires the power adapter to allow for daisy chaining more
banks of switches.
