into its power jack, then plug the power adapter
into an AC source.

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.
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 GCS1758 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 p. 45.
Switches cannot be cascaded beyond the third
level. Once you have finished cabling up (see Two/
Three 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.
