Frequently Asked Questions (FAQ)
Can I hot-swap this IS200GFOIH1B into a running Mark VIe system?
We strongly advise against it. The GFOIH1B 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 IS200GFOIH1A and the IS200GFOIH1B?
The H1B has a specific hardware configuration with unique features that differ from the H1A. The exact differences vary by production batch. We can provide specific details for your unit if you contact us with the serial number.
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 145,000 hours for the H1B revision. We have seen these units exceed 15 years in field service.
