Powers devices over the cable

IEEE 802.3at compliant ports carry power alongside data on a single Ethernet cable.

4SFP ports

Fiber uplink

100/1000Base-X SFP ports link long-distance fiber runs to the backbone.

24Gbps

Non-blocking switching

Store-and-forward architecture forwards packets with 7 µs latency.

30ms

Ring recovery time

O-Ring, Open-Ring, O-Chain and MRP move a broken link to the backup path across a 250-unit ring.

13.2Watts

Low consumption

Dual DC inputs run on 50~57 V DC; when one source drops, the other takes over.

IN DAILY USE

Serves in rolling stockIt follows the EN50155 and EN50121-4 requirements and operates under on-board vibration and shock.

Clocks stay alignedIEEE 1588v2 clock synchronization keeps measurement and recording devices on a shared time base.

Puts PoE ports on a scheduleScheduled PoE configuration switches ports on at a set time, and the auto-ping check restarts a device that stops answering.

ApplicationsOn-board rolling stock networks·IP camera power lines·DIN-Rail cabinet installations

Reverse polarity protection is not present on this model.
