LAN-RING System PoE++ Managed Switches
Ring topology LAN-RING
LAN-RING is suitable especially for extensive alarm and automation systems. The core of the system are industrial switches
supporting ring topology with fast reconfiguration in 30ms. The swithes are apart from Ethernet port (optics / twisted pair)
equipped with other ports such as RS485, RS422, RS232, digital inputs, relays outputs, TTL inputs/outputs and audio inputs/
outputs (see the table). That enables interconnection of multiple systems (IP CCTV, automation, LAN, ESS, PIDS etc.) using one
optical fiber.
* it is not possible to use both interfaces at the same time
5-year ALL INCLUSIVE warranty
For all LAN-RING system devices we provide
5-year ALL INCLUSIVE warranty including damage caused by excessive voltage
(for
detailed specification see “Warranty ALL INCLUSIVE” on our webpages www.metel.eu).
Overvoltage protection 1kA on FE ports
Overvoltage protections of LAN-RING switches guarantee reliable operation even
in outdoor installations. The optimum placement of the switch, devices and cables
connected to the switch is in protection area
of a lightning rod, i.e. ZBO0
B
zone acc. to IEC 62305-4.
The switches ports are protected in two ways:
- two-level class D protection consisting of lightning
arresters, separating impedances and transils
- fine class D protection consisting of transils
* When connecting switches in outdoor environment we recommend
having all ports with supply feed longer than 10m protected by protections: .
