L3 Managed Rack Mount Full Gigabit/10Gigabit Ethernet Switch
RRS4252 is an intelligent 10Gigabit/Gigabit capable Layer 3 Ethernet switch designed to withstand the harshest environments of utility substations and rolling stock applications.
RRS4252 supports up to 48 X 10/100/1000Base-TX ports and 4 X 10G ports, or 36 X 10/100/1000Base-TX ports, 12 X 100/1000 SFP ports and 4 X 10G ports, or 24 X 10/100/1000Base-TX ports, 24 X 100/1000 SFP ports and 4 X 10G ports. The switch provides layer 2 redundancy support through functions such as STP/RSTP/MSTP and ERPS, as well as layer 3 redundancy VRRP that assuring protection of all mission critical network applications. In addition, RRS4252 supports various advanced layer 3 routing features such as static and dynamic routing features including RIP and OSPF, and even multicast routing PIM-SM. RRS4252 can be managed via the Web UI, Telnet/SSH, and Console (CLI). The switch accepts a wide voltage range of 12-36VDC, 36-58VDC, or high voltage of input 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.
