Section 3.5.3
Transient Suppression
All copper Ethernet ports on RuggedCom products include transient suppression circuitry to protect against
damage from electrical transients and to ensure conformance to IEC 61850-3 and IEEE 1613 Class 1. This
means that during a transient electrical event, it is possible for communications errors or interruptions to occur,
but recovery is automatic.
NOTE
RuggedCom does not recommend the use of copper cabling of any length for critical, real-time,
substation automation applications.
RuggedCom also recommends against the use of copper Ethernet connections to interface to devices in the field
across distances which could produce high levels of ground potential rise (that is, greater than 2500V) during
line-to-ground fault conditions.
Section 3.6
Fiber Ethernet Ports
Depending on the product order code, the RuggedBackbone™ RX5000 can be equipped with LMs and SMs with
several different types of fiber optic ports. The Transmit (TX) and Receive (RX) connections of each port must be
properly connected and matched for proper link establishment and operation. The following figures show the front
and top views of each supported fiber optic connector type to assist in identifying the proper cable connection
orientation.
