KVM Over the NET™ User Manual
Two Stage Installation
To control even more servers, up to 16 additional KVM switches can be cascaded from the KVM ports of the original KN1108v / KN1116v. As many as 256 servers can be controlled in a complete two stage installation.
In a cascaded installation, the KN1108v / KN1116v is considered the First Stage unit, the cascaded switches are considered Second Stage units.
Note: The cascaded KVM switch shown in the example is the KH1516. See Supported KVM Switches, page 259, for a list of other switches.
To set up a two stage installation, refer to the diagram on page 26, and do the following:
1.Make sure that power to all the devices you will be connecting, including all preexisting devices on the installation, are properly grounded and have been turned off.
2.Use Cat 5e cable to connect any available KVM Port on the First Stage unit (the KN1108v / KN1116v) to a KVM Adapter Cable (as described under KVM Adapter Cables, page 7).
3.Plug the adapter cable’s KVM connectors to the Keyboard, Video, and Mouse Console ports of the Second Stage unit.
Note: The distance between the First Stage unit and the Second Stage unit must not exceed 40m or 50m based on the KVM adapter cable used.
4.Use KVM cable sets (as described in the Cables section of the cascaded KVM switch’s User Manual), to connect any available KVM port on the Second Stage unit to the Keyboard, Video, and Mouse ports of the server you are installing.
5.Plug the power cord that came with the cascaded KVM switch into its Power Socket, and then into an AC power source.
6.Repeat these steps for any other Second Stage units you wish to connect.
7.Power on the Second Stage unit(s), then power on the First Stage unit.
8.Turn on the power to all the servers.
Note: The Power On sequence requires that all Second Stage switches be powered on first. After all Second Stage switches are powered on, the First Stage switch can be powered on. After all the switches are powered on, the servers can be powered on.
