Initial power-up
Make sure both computers and the KVM switch are powered down during installation. After
connection, you may power up the computers; the KVM switch draws insignificant powers from the
computers for operation. The power adapter may be connected to the switch but not required. It is
required if you plan to use the Sun keyboard’s Power-Up key.
