Frequently Asked Questions (FAQ)
Can I hot-swap this IS200EXCSG1ABA into a running Mark VIe system?
We strongly advise against it. The EXCSG1ABA has shown unpredictable behavior when inserted into a powered backplane. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance.
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 ABA revision. We have seen these units exceed 15 years in field service.
