Three Stage Installation
The procedures for setting up a three stage installation are essentially the same
as for a two stage installation. With a three stage setup, as many as 512
computers can be controlled in a complete installation. A table showing the
relation between the number of computers and the number of switches needed
to control them is provided on page 64.
Note: Switches cannot be cascaded beyond the third level.
To set up a three stage installation, refer to the Three Stage Installation diagram
on the next page. Once you have finished cabling up (see Two Stage
Installation for details, if necessary), power up according to the following
sequence:
1. For each Third Stage unit, plug the power adapter cable into the switch's
Power Jack; plug the power adapter into an AC source.
2. For each Second Stage unit, plug the power adapter cable into the switch's
Power Jack; plug the power adapter into an AC source.
3. Power On the First Stage unit.
4. Turn on the power to all the computers.
Note: The Power On sequence requires that all Third Stage units be powered
on first. After they are all on, the Second Stage units must be powered
on next. After all the Second Stage units are on, the First Stage unit must
be powered on. Only after all the switches have been powered on in this
sequence, can the computers be powered on.
