The unit is Failsafe and never itself becomes a point of failure in the electrical
ethernet mode. The “protected interface” automatically reverts to and reconnects to the “primary interface” even in a power down condition.
VCL-2724 PRP / HSR Switch is a simple, compact, easy-to-use solution designed to be used in critical Ethernet networks
that cannot afford packet loss which may otherwise occur during ring-recovery, or switchover upon failure of either one of the Ethernet LANs. The
VCL-2724 is designed to carry critical Ethernet data over two parallel LANs with zero packet loss.
The VCL-2724 PRP / HSR Switch may also be used to carry Ethernet data in over an HSR ring with absolutely no packet
loss. VCL-2724 PRP / HSR Switch is the only presently available in the industry which ensures that the PRP / HSR Switch never itself becomes a point of
failure, even in power down condition.
Failsafe* : In Electrical Ethernet Mode.
In-built Electrical and Optical Ethernet Interface Options. Provides both optical and electrical ethernet
interface options on the “Protected side” as well as the “PRP sides”.
Ultra-Resilient and Failsafe* – Never itself becomes a point of failure in the electrical ethernet mode.
The “protected interface” automatically reverts to and reconnects to the “primary PRP interface” even in a power down condition.
It is the only such PRP solution available in the industry which ensures that the VCL-2724 PRP Switch, itself, never becomes a
point of failure!!!
Applications include critical Ethernet network applications such as Smart-Grid, electrical substation automation,
industrial automation, aircraft controls, automotive applications and military communications.
**Electrical/Optical user selectable Ethernet combo ports either Electrical Ethernet or Optical Ethernet will work.
