Hardened Ethernet switches for Train station and Electrical substation
These hardened switches support -40°C to +75°C and comply with environmental EN50121-4 regulation for Train-Station and IEC61850-3/IEEE1613 for automatic system in electrical substations.
All Layer2 switches are supporting powerful Ethernet stacks.
They
support VLAN per port, tagging IEEE802.1q and GVRP, the QoS IEEE802.1p
with 4 queues. The bandwidth rate control is done per port
egress/ingress.
The access security can be set locally per port on
Mac Address locking with up to 24 static Mac A. per port or externally
in IEEE802.1x with Radius server.
Management is operate over RS232
consol port or the Ethernet ports in CLI, Telnet, Web browsing, SNMPC
V1, 2, 3 with onboard RMON probe.
As protection they are supporting
RSTP/MSTP and Alpha Ring a proprietary ring protection with a recovering
period below 15ms.
DIN-rail hardened switches models are build in aluminum, IP30, fanless, they are supporting -40°C to +75°C working temperature. They are powered by redundant 12 to 48VDC power or by 12VDC adapter with latched jack.
