Inventory quantities are subject to availability and are not guaranteed until the order is placed.
The Cisco C9400-PWR3200DC is a 3200-Watt DC-input power supply module designed for the Cisco Catalyst 9400 Series switches. Here are its key features and specifications:
Power Supply Features:
Supports DC input voltage range from -40 to -72 VDC, with an extended range up to -75 VDC.
Provides a regulated 55-VDC PoE-compliant main output and a 3.3-VDC standby output.
Equipped with dual independent DC inputs, each with isolated circuits, allowing power from separate sources or a single suitable source.
Includes DC-input reversal protection to survive input polarity reversal up to the full input voltage rating.
Has a self-cooling mechanism requiring a minimum airflow of 9.5 cubic feet per minute at full load.
Features a release latch to prevent accidental removal and an On/Off power button on the front panel with two modes: Auto-on (default) and Protected.
Built-in front-facing passive RFID tag for identification.
Electrical Specifications:
Nominal DC input current: 36 A per input (72 A total) at -48 to -60 VDC.
Maximum DC input current: 44 A per input at -40 VDC.
Output power capacity: Approximately 3190 W at 55 VDC and 10 W at 3.3 VDC standby.
Output holdup time: 8 milliseconds.
Heat dissipation: Approximately 950 BTU per hour.
Weight: About 6.61 lb (3.0 kg).
Operational Details:
The power button toggles the main output on/off; standby power remains available when DC input is applied.
Auto-on mode allows automatic start/restart on power application or restoration.
Protected mode requires manual power button press to restore operation after power loss.
Supports redundant and combined power supply configurations.
Compatible with Cisco Catalyst 9400 Series switches and supports hot-swappable installation.
This power supply is suitable for high-availability environments requiring robust DC power input with redundancy and protection features.
