Communication Ports Receive and transmit network traffic, as well as provide remote Web access to the
RUGGEDCOM ROS operating system. For more information, refer to:
•
Section 3.1, “Connecting to the Device”
• Section 4.1, “Copper Ethernet Ports”
• Section 5.4, “Copper Ethernet Port Specifications”
• Section 4.2, “SFP Transceivers”
RS232 Serial Console Port For interfacing directly with the device and accessing initial management functions. For
information about connecting to the device via the serial console port, refer to Section 3.1,
“Connecting to the Device” .
Failsafe Alarm Relay Terminal Latches to default state when a power disruption or other alarm condition occurs. For more
information, refer to:
•
Section 2.2, “Connecting the Failsafe Alarm Relay”
• Section 5.2, “Failsafe Relay Specifications”
Power Supply Terminal A pluggable terminal block. For more information, refer to:

• Section 5.1, “Power Supply Specifications”
Section 1.3
Cabling Recommendations
All copper Ethernet ports on RUGGEDCOM products include transient suppression circuitry to protect against
damage from electrical transients and conform with IEC 61850-3 and IEEE 1613 Class 1 standards. This means
that during a transient electrical event, communications errors or interruptions may occur, but recovery is
automatic.
Siemens does not recommend using copper Ethernet ports to interface with devices in the field across distances
that could produce high levels of ground potential rise (i.e. greater than 2500 V), during line-to-ground fault
conditions.

High Availability Seamless Ring Operation
Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR) are two mechanisms defined
by the IEC 62439-3 standard to provide hitless network recovery. Unlike Spanning Tree Protocol (STP), which
