B2.0 -48VDC, 24VDC & 125VDC POWER OPTION, THEORY OF OPERATION

The -48VDC, 24VDC & 125VDC power options are designed using diodes

correctly applied to the two inputs. It protects the 8000X from incorrect DC input connections. An incorrect polarity connection, for example, will neither affect the 8000X, its internal power supply, nor will it blow the fuse in the internal power supply.

The manual power “On-Off” Switch (optional) is used for powering the unit on and off when it is placed into or taken out of service.

B3.0 APPLICATIONS FOR DC POWERED ETHERNET HUBS
