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.
