the hub from incorrect DC input connections. An incorrect polarity connection, for example, will neither effect the hub, nor its power supply internally, nor will it blow the fuse in the internal power supply.

Disconnecting the power source is used for powering the hub on and off when it is placed into or taken out of service.
