Description
Product Introduction
The GE IS200EISBH1AAA is a Mark VIe series managed Ethernet switch module that provides 8 ports of network switching and routing capability for Mark VIe control system communication. This I/O pack enables network connectivity for multiple devices, providing the network infrastructure for turbine control system communication.
The AAA suffix denotes the premium configuration with enhanced switching features, advanced diagnostics, and specific hardware configuration. In our field experience, the EISB provides the network backbone for Mark VIe turbine control systems. For facilities requiring managed Ethernet switching capability, the EISB provides the necessary infrastructure.

Frequently Asked Questions (FAQ)
Can I hot-swap this IS200EISBH1AAA into a running Mark VIe system?
We strongly advise against it. The EISBH1AAA has shown unpredictable behavior when inserted into a powered backplane. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance.
What is the difference between the EHFC and EISB modules?
The EHFC is an Ethernet interface module. The EISB is a managed Ethernet switch providing network switching and routing capabilities.
How many devices can this switch support?
The EISB supports 8 Ethernet connections. Network capacity depends on specific configuration and network loading.
How do I verify this is a genuine GE module?
We source exclusively from GE-authorized liquidations. Our verification includes OEM packaging inspection, serial number cross-check against GE records, and PCB inspection for GE-specific markings.
What is the expected lifespan of this unit?
We see MTBF around 140,000 hours for the AAA revision. We have seen these units exceed 15 years in field service.
