Installation
The BEB units are easy to install, and ready to mount with in the 19” racks, or cabinets.
As shown in the diagram above, you can mount each BEB in the 1U configuration and daisy chain
them using the BEB connection ports. The BEB units must be connected one at a time, not all at
once. When disconnecting and then re-connecting the BEB to a different SPX+ base unit you will
need to reset the BEB using the reset button on the BEB unit.
The LED on the BEB units will show the communication / activity between the SPX+ and and the BEB
unit. The BEB’s are powered by the external 5VDC PSU that is included in the shipment.
The BEB connectors are straight RJ-12 to RJ-12 and the wiring diagram is shown in the chart above.
Cables are included however normal CAT5 or CAT6 can be used for these RJ-12 connections.
