Two Stage Installation
To control even more computers, up to eight additional KH88 units can be cascaded from the CPU ports of the First Stage unit. The cascaded KH88s that connect back to the First Stage unit are considered Second Stage units.
As many as 64 computers can be controlled in a complete two stage installation. A table showing the relation between the number of computers and the number of KH88 units needed to control them is provided on p. 43.
Note: 1. Mixing different KVM switch models on the same installation can cause problems with OSD port switching. We strongly recommend that all cascaded units be the same model as the First Stage unit.
2.If you are adding this switch into an already existing KH88 configuration, be sure to make it the First Stage unit. Otherwise, you won’t get the benefit of its improved OSD features and functions.
To set up a two stage installation, do the following:
1.Make sure that power to all the devices you will be connecting up, including all preexisting devices on the installation, have been turned off.
2.Use a KVM cable set (described in the Cables section, p. 4), to connect any available CPU Port on the First Stage unit to the Console Port connectors of the Second Stage unit.
3.Use KVM cable sets (described in the Cables section, p. 4), to connect any available CPU port on the Second Stage unit to the Keyboard, Video, and Mouse ports of the computers you are installing.
4.Plug the power cord that came with this package into the KH88’s Power Socket, and then into an AC power source.
5.Repeat these steps for any other Second Stage units you wish to connect.
