Belden Hirschmann Ethernet Switch, RJ45 Ports 4, 100Mbps, Managed

4 and 8 port rail switches with management function. For setting up flexible Ethernet networks acc. to IEEE 802.3 with optical fibre cables and twisted pair technology. High failure reliability thanks to the option of redundant data connections and a redundant voltage supply. Reconfiguration time with 50 switches in ring max. 500 ms (typ. 50 ms) thanks to Hyper-Ring technology. With 50 switches in a ring, the reconfiguration time is <500 ms thanks to the HIPER ring technology. Four priority queues in accordance with IEEE 802.1 D. Management: SNMP v1, v2, v3, WEB management, serial (V.24). Suited for the use in rugged industrial environment. Integrated message contact for diagnostic purposes and for functional monitoring. Twisted pair (TP) and optical fibre cable outlets to the front. For TP cables: 10/100 Base-TX RJ 45 sockets, auto-crossing, auto-negotiation, auto-polarity. For multimode fibres (MM):100Base-FX SC sockets.
