FAQ

1. Q: Can GE 8724-CA-PS work independently without 8920-PS-DC power module and PAC8000 SIS rack?
   A: It must be used with 8920-PS-DC and PAC8000 rack, cannot run as standalone hardware.
2. Q: What are typical carrier failure symptoms?
   A: Poor bus contact, unstable power transmission, loose terminal connection, intermittent SIS rack communication faults.
3. Q: How to complete commissioning and diagnosis?
   A: Check carrier mounting, terminal wiring and backplane contact; use SIS configuration software to read power module health status.
