Frequently Asked Questions (FAQ)
Can I hot-swap this IS200GDDDG1AAA into a running Mark VIe system?
We strongly advise against it. The GDDDG1AAA 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 IS200GDDDG1A and the IS200GDDDG1AAA?
The AAA has enhanced I/O features, advanced diagnostics, and improved performance over the G1A. 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 150,000 hours for the AAA revision. We have seen these units exceed 18 years in field service.
