C9400-PWR-3200DC Description
C9400-PWR-3200DC is a Cisco Catalyst 9400 Series 3200W DC-input power supply module for Catalyst 9400 modular switch chassis that use DC site power.
This power supply is intended for Catalyst 9400 deployments where the power design is based on DC input rather than AC input. Cisco documents dual DC inputs, 55 VDC main output, 3.3 VDC standby output, and support for redundant or combined power supply modes on Catalyst 9400 chassis.
Before requesting a quote, confirm the chassis model, DC plant voltage, feeder and grounding design, redundancy mode, total switch power budget, and whether the order needs the base SKU or spare-part form.

Application Scenarios
Use C9400-PWR-3200DC when a Catalyst 9400 chassis is planned around DC site power and the bill of materials needs the 3200W DC-input PSU family.
Choose this SKU when an installed Catalyst 9400 chassis already uses 3200W DC power supplies and the maintenance plan needs a matching replacement or spare module.
Use C9400-PWR-3200DC in Catalyst 9400 power designs that require Cisco-supported redundant or combined power supply modes. Confirm the active and standby PSU mix before quoting.

- Choose C9400-PWR-3200DC when the Catalyst 9400 chassis must use DC input power rather than AC input power.
- Compare C9400-PWR-3200AC when the site uses AC input and still needs the 3200W power class.
- Compare C9400-PWR-3200ACT when the order specifically calls for the 3200W Titanium power supply option.
- Compare C9400-PWR-2100AC only when the AC power budget supports a lower 2100W power supply class.
Selection Guide
1. Confirm the site DC power range
Select C9400-PWR-3200DC only when the site DC plant, cabling, and protection plan match Cisco’s documented DC input range for this PSU.
2. Size the chassis power budget before quote approval
Check supervisor modules, line cards, fan tray, PoE load, and redundancy target before treating a 3200W DC power supply count as final.
3. Verify the redundancy or combined power mode
Confirm whether the Catalyst 9400 chassis will use combined mode, N+1 redundancy, or N+N redundancy, especially if AC and DC power supply modules are mixed.
4. Match the order to the installed PSU family
For replacement orders, match the existing PSU type and capacity. For new builds, confirm whether the order requires the base SKU or the spare-part ordering form.
