Key Features of the AC-Input Power Supply
- Self-Cooling Fan:
- C9400-PWR-2100AC/3200AC: ≥7 CFM at full load
- C9400-PWR-3200ACT: 19.87 CFM at full load (single fan)
- Regulated DC Outputs: 55 VDC PoE-compliant main output; 3.3 VDC standby whenever AC is present
- Single-Phase AC Support: Accepts 100–240 VAC (phases may vary across modules or cords due to input isolation)
- Front-Panel Safety: Release-latch and cord-retention to prevent accidental module or cord removal
- Redundancy Modes: Configurable as single (non-redundant) or dual (redundant); combined output power:
- 200–240 VAC → 3200 W (3200ACT) / 2112 W (2100AC)
- 100–120 VAC → 1570 W (3200ACT) / 950 W (2100AC)
- Built-In RFID Tag: Front-facing, passive UHF tag for asset tracking (requires compatible RFID reader/software)
