Plug the included power cords into the KVM switch’s Power Sockets, and then into a Surge Protector, Uninterruptible PowerSupply (UPS) or PDU.10. Turn on the power to the KVM switch. Once it is powered up, turn on the power to the connected computers.Single-Stage InstallationTwo-Stage InstallationHardware SetupUp to 32 additional B064-016 KVM switches can be cascaded from your unit’s KVM ports, expanding the number of connectedcomputers/servers up to 256. In a cascaded installation, the top KVM Switch is considered the first-stage unit, the cascadedswitches are considered second-stage units.To set up a two-stage installation:1. Ensure that power to all the devices you will be connecting, including all pre-existing devices on the installation, have beenturned off.2. Use Cat5e/6 cabling to connect an available KVM port on the first-stage unit to a B054-001-PS2 or B055-001-PS2 SIU.Note: Although USB SIUs will allow you to cascade to a second-stage KVM, only PS/2 SIUs will properly display the cascaded KVM in the OSD. Whenconnected via PS/2 SIU, the cascaded KVM will be displayed as an expandable port, allowing you to easily access the connected computers. Whenconnected via USB SIU, the cascaded KVM will be displayed as an ordinary port. To access computers connected to the KVM, you will have to use thecascaded KVMs OSD.3. Plug the SIU’s KVM connectors to the Keyboard, Video, and Mouse Console ports of the second-stage B064-016 unit.Note: The distance between the second-stage unit and the first-stage Unit cannot exceed 164 ft. (50 m).4. Use the appropriate KVM Cable Kits (See the Second Stage KVMs owner’s manual), to connect any available KVM port on thesecond-stage unit to the Keyboard, Video and Mouse ports of the computer/server you are installing.
