2.6 CONNECTIONS
Because the PoE voltage provided by the injector is a fairly high 48 volts, the Ethernet cable
between the injector and the LX Breadcrumb should be made before powering up the injector.
If cable is plugged in with a live injector, a large spark will be produced that is not good for the
electronics.
In order to avoid sparking and possible damage to the unit, be sure to connect
the powered Ethernet cable to the BreadCrumb LX before applying power to
the power supply.
The LX supports two Ethernet ports. Both ports operate in a 100BASE-TX or 10BASE-T
configuration and support auto MDI/MDIX for automatically switching twisted pair inputs and
outputs. Therefore, any combination of straight-through or crossover Ethernet cable
combination can be used.
