GE’s MiCOM H Series Ethernet switches use cutting edge redundancy protocols to offer superior network availability and extremely fast reconfiguration in the event of link failure. The MiCOM H Series Ethernet switches use a combination of advanced redundancy protocols and fiber-optic connections to ensure the reliability, availability and dependability of substation communications networks. All this while maintaining the flexibility of being able to be

connected to standard Ethernet networks - ideal for substation refurbishments or upgrades.

The MiCOM H Series switches use either the Dual Homing Star or Self Healing Ring protocols and are available in standalone, embedded and PCI card (for integration into a PC) variants. As part of GE’s Digital Control Systems (DCS), the MiCOM H Series switches are fully compatible

with our protection relays, bay computers and gateways.

Key features:

• Cutting edge redundancy protocols: the Dual Homing Star or Self Healing Ring
• Flexible connectivity: different port variants are available – copper or fiber (single mode or multi mode) with ST, SC or LC connectors
• Monitoring capabilities: set an alarm to monitor link failure using either the inbuilt watchdog relay (contact) or via communications
• Increased reliability: standalone switches have redundant power supplies
• Suitable for harsh environments: The MiCOM H Series switches are designed to work in harsh environments such as substations

Key benefits:

• Superior network availability
• Very fast network reconfiguration
• Easy to install and configure
• Monitoring capabilities
