If more than sixteen servers are to be connected, then cascading of the PC
ServerSwitch 2x16 is necessary. In a cascade environment, the first unit that is
installed is considered the "Master Unit." All information is stored in the Master
Unit. Cascading the units is very simple.
If the existing PC ServerSwitch 2x16 unit has been installed and running, it is not
necessary to turn off the power to the Unit. The installation of additional units can
be accomplished without any interruption to the existing servers.
STEP 1 - Connect CONTROL Cable
Connect the DB9 Serial data cable (supplied with each PC ServerSwitch 2x16)
from the Master Unit "Control Out" port to the first Aux Unit "Control In" port. Make
certain that these cables are securely fastened to the units. These data cables
carry all mouse, keyboard, and control data necessary for cascading units. Follow
this procedure for as many Aux units
If more units are cascaded, connect the Control Out port to the Control In port of
the next unit to be cascaded, using a DB9 Female to Male serial cable.
STEP 2 - Connect Video Cascade Cables
Connect the "Video Cascade In" ports on the Master Unit to the "USER/OUTPUT"
video ports (Port A Output to Port A Cascade In, Port B Output to Port B Cascade
In). This will allow the video signals from the Aux units to reach the Consoles that
are connected to the Master unit. Follow this procedure for as many Aux units (one
Master plus 5 Auxiliary units, max) as required for the servers.
STEP 3 - Turn the Auxiliary Unit On
Turn on all of the Auxiliary units that were installed. Connect the servers to these
units as done in the earlier installation for a single unit.
To install a PC ServerSwitch 2x16 as the new master, turn the old master off,
connect it, and then turn it back on. Turning off the old master may affect PCs
connected to it, so it is recommended that you shut down any PCs connected to
the old master before performing this installation.
