Power Supplies for Additional Components
To add additional components to the system, add an inline or rackmount power supply to the discussion unit chain.
Inline Power Supply
Use the PI-6000 power inserter to add an inline power supply for approximately 50 more discussion units. The unit
may be connected at any point in the chain to power the additional components. Multiple PI-6000 units can be
used to reach the maximum 250 supported discussion units.
Note: The PI-6000 does not refresh the data signal, so total cable length cannot exceed 120 m.
