Product Introduction

RRS3128 is an intelligent full gigabit Layer 2 Ethernet switch designed to withstand the harshest environments of utility substations and rolling stock applications.

RRS3128 supports 24 x 10/100/1000Base-T(X) RJ45 ports and 4 x 100/1000Base-X SFP ports, or 16 x 10/100/1000Base-T(X) RJ45 ports, 8 x 100/1000Base-X SFP ports and 4 x 1000Base-X SFP ports, or 8 x 10/100/1000Base-T(X) RJ45 ports, 16 x 100/1000Base-X SFP ports and 4 x 1000Base-X SFP ports, or 24 x 100/1000Base-X SFP ports and 4 x 1000Base-X SFP ports. The switch is IEC61850-3 and IEEE1613 compliant and provides redundancy support through functions such as STP/RSTP/MSTP and ERPS that assuring protection of all mission critical network applications. RRS3128 can be managed via the Web UI, Telnet/SSH, and Console (CLI). The switch accepts a wide voltage range of 77-300VDC or 85-264VAC. The switch is made of IP40 galvanized steel and has a wide operating temperature range from -40°C to +85°C, which is suitable for the harshest of environments without the use of fans.
