Key features and benefits: why Henrich won:
- Redundant Network Recovery in under 5 ms for Layer 2 and 15ms for Layer 3
- Customised Layer 3 Managed Switch Software for China Rail On-Board unique needs
- Robust Design including operating Temperatures of -40°C to 75°C
- IP67 Waterproof Housing
- Robust M12 Connectors for rugged reliability
- Small Size to optimise control cabinet space
- Gigabit and PoE options
Henrich switches are being used as the backbone for China Rail next generation Train Control Network. China Rail evaluated 20 different global switch manufacturers over 18 months before choosing Henrich as their preferred Ethernet switch. A highly critical factor in choosing Henrich is the switches extremely fast recovery should one of the ring connections fail.
The switch will recover and start communicating in faster than 5 ms for the Layer 2 switch and 15ms for Layer 3, the fastest recovery times in the industry! In addition to the switches robust performance, the Henrich Layer 3 software had to be customized to meet the unique needs of China Rail.
The HEST12M series is small in size to meet the critical space needs in the control cabinet on board. The M12 connectors provide a robust and waterproof connection to hold up to the most extreme environments. The fan-less cooling design adds to its reliability, along with its dual power supply inputs. It is also offered in 10MB/100MBps and gigabit and PoE options.
