Frequently Asked Questions (FAQ)
Can I hot-swap this IS200EPSDG1A into a running Mark VIe system?
We strongly advise against it. The EPSDG1A 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 power output capability of this module?
Power output capability varies by configuration. Verify with OEM datasheet for specific power ratings.
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 EPSDG1A. We have seen these units exceed 18 years in field service.
