Sel -2725 Installation And Maintenance Manual

SEL-2725 Unmanaged Ethernet Switch
Features and Benefits
The SEL-2725 is an unmanaged five-port Ethernet switch and copper-to-fiber media converter. Single- or multimode
fiber optics are available to accommodate a wide range of utility and industrial applications. The environmental specifi-
cations exceed the requirements of IEEE 1613 Class 2 and IEC 61850-3, making it suitable for operation in harsh envi-
ronments, such as electric utility substations or industrial plants.
➤
Easy Installation. The SEL-2725 has no settings. Copper ports autoconfigure for crossover cables, autospeed
detects for 10 or 100 Mbps links, and automatically detects half- or full-duplex operation.
➤
Reliable Power Supply. 10–275 Vdc power supplies exceed all harsh environmental standards along with a
3,000 year MTBF.
➤
Robust Performance. Operates above the required temperature range (–40° to +85°C). Exceeds the requirements
of IEEE 1613 and IEC 61850-3.
Use as a multiport media converter to connect Ethernet 10/100BASE-T devices to one location or equipment rack. Use
the 100BASE-FX multimode or 100BASE-LX10 single-mode fiber-optic port options to interconnect devices with the
central or managed Ethernet switch. Keeping the electrical connections short and localized greatly reduces the possibil-
ity of induced noise.
