Schweitzer Engineering Laboratories' SEL-2730M Managed 24-Port Ethernet Switch
SEL-2730M managed 24-port Ethernet switch meets or exceeds IEEE 1613 (Class 2) and IEC 61850-3 communications standards. The design minimizes printed circuit boards and interface points. With no moving parts, the base-model SEL-2730M has 16 10/100 Mbps ports, and four for Gigabit Ethernet. Upgrade the 10/100 Mbps drop ports to fiberoptic interfaces and add four additional small-form-factor pluggable (SFP) fiberoptic Gigabit Ethernet ports. Dual hot-swappable power supplies support simultaneous ac and dc voltage sources.
