Two Stage Installation - ATEN CS-128A User Manual

4. Turn on the power to the computers.
Note: If you choose to use external power, the CS-128A must be plugged
in and receiving power before turning on the power to the computers.

Two Stage Installation

To control even more computers, up to eight additional CS-128A units can be
cascaded from the CPU ports of the First Stage unit. The cascaded Master
Views 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 Master View units needed
to control them is provided in the Appendix.
Note: Mixing different Master View models on the same daisy chain can cause
problems with Hotkey and OSD port switching. We strongly
recommend that you use CS-128As for all the cascaded units.
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
(unplug the First Stage unit if it is plugged in to an AC source).
2. Use a connector cable set (described in the Cables section, p. 3), to connect
any available CPU Port on the First Stage unit to the Console Port
connectors of the Second Stage unit.
3. Use connector cable sets (described in the Cables section, p. 3), to connect
any available CPU Port on the Second Stage unit to the monitor, keyboard
and mouse ports of the computers you are installing.
4. Repeat steps 1 - 3 for any other Second Stage units you wish to connect.
5. For each Second Stage unit, plug the power adapter cable into the Master
View's Power Jack; plug the power adapter into an AC source.
6. Plug in the power adapter for the First Stage Master View unit.
7. Turn on the power to all the computers.
Note: The Power On sequence requires that all Second Stage units be
powered on first. After all the Second Stage units have been powered
on, then the First Stage unit must be powered on next. After the
Second and First stage units have been powered on, the computers
can be powered on.
