Introduction
The HP 1x4 USB/PS2 KVM Switch is a four-port keyboard, video, and mouse (KVM) switch
combined with a two-port USB hub. As a KVM switch, four computers can be accessed from
a single keyboard, mouse, and monitor console. Keyboard and mouse data can be transferred
to the computers using a USB connection, or with the traditional PS/2 connection. If a USB
connection is used, the two-port USB hub is available to each of the computers, allowing
each computer to access any peripherals connected to the hub on a one-computer-at-a-time
basis.
• Dual-function KVM/USB switch
• Ability to control four computers and two additional USB devices with one console
NOTE: Both USB peripheral ports on the switch rear panel will not function unless USB KVM
