The required 24 VDC power for each group of QM inputs and QM outputs can be

supplied in a variety of ways. The following wiring diagram suggests one method of

applying 24 VDC power to the QM ports. In this configuration, the C2N-SPWS300

can supply up to 75 watts of power to each group of QM ports to ensure that

sufficient power is available for QM devices that are connected to the MD8x8. The

C2N-SPWS300 can also supply the power required by the MD8x8.

NOTE: The MD8x8 can only be powered by the 4-position terminal block

connector labeled “NET”. Power cannot be supplied from network devices that are

connected to the mini-terminal block connectors.

NOTE: The Y and Z Cresnet data lines from the network are connected to the NET

connector, which is internally wired to the 4-position mini-terminal block connector

at each QM connector.

NOTE: In the configuration shown, the C2N-SPWS300 can operate in the “PWR

ON” position or the “PWR OFF SLAVE” position. For more information, refer to

the latest revision of the C2N-SPWS300 System Power Supply Operations Guide

(Doc. 8190).
