Tiered Switch Configurations
In tiered systems, the user can connect additional console switches to ports on a
primary unit. That is, console switches can be tiered in primary/secondary
configurations to allow one primary console switch to switch between computers or
other console switch units. Tiering involves linking the physical keyboard, mouse,
and monitor of the secondary units to computer ports on the primary unit. For
example, one 8-Port primary unit can accommodate eight secondary console switch
units. A system with eight servers connected to each of the eight secondary console
switches would provide a 1x64 concentration.
Figure 3-9: Tiered configuration
When connecting a secondary unit to one of the ports of the master unit, the user
must indicate this connection to the primary unit by performing the “Assigning
Specific Device Types” procedure described in Chapter 5. This involves entering a
secondary unit designation for the associated port number instead of a monitor type.
Use the designation 4-Port for a 4-port secondary and 8-Port for an 8-port
secondary.
The OSD allows secondary ports to be treated much like ports on the primary console
switch. It may be helpful to name each secondary unit as described in “Assigning
Unique Names to Computers” in Chapter 5.
