Connect Adjunct Power

The attendant console requires -48 VDC adjunct power from pins 7 and 8 of the information outlet. Only 3 consoles can be powered by the cabinet from the AUX connector. Power the primary console from the cabinet so it has the same power failure backup as the system.

1.For terminals needing adjunct power, wire -48 VDC and ground to appropriate pins on the terminal. See Figure 5-3. Use the 400B2 adapter when connecting local -48 VDC power to a modular plug.
