- Metal shielding
Working Principle AC input after EMI filtering and rectification feeds a switching converter; high-frequency isolation steps down and rectifies to multiple DC rails, delivered through backplane gold fingers to cards. Monitoring circuits protect on faults.
Installation Requirements
- Insert slot with power off
- AC input by voltage
- Rack grounding
- Temperature 0 °C to +60 °C
- Verify output voltages after power-up
- Lock card
Precautions
- Confirm redundancy before online replacement
- AC voltage must not be wrong
- DC polarity correct
- Store spares in moisture-proof packaging
- Periodically check output voltage
- Confirm CPU power status after replacement
