C9K-PWR-1600WDC-R Description
C9K-PWR-1600WDC-R is a Cisco Catalyst 9500 Series 1600W DC power supply module for the high-performance C9500-32C switch, used as a field-replaceable spare or replacement in deployments that run on a -40 to -72 VDC power plant. Cisco lists it as the supported 1600W DC PSU for that chassis, with DC input current up to 40A at -48VDC, 12V main output at 133A plus 12V standby at 3A, and an Amphenol C10-638976-000 input receptacle with a 70A power cord requirement.

Application Scenarios
Use C9K-PWR-1600WDC-R when the installed Catalyst 9500 High Performance switch is C9500-32C and the replacement PSU must match a DC-input 1600W power design.
Select this module for C9500-32C deployments where the site standard is -48VDC-class power and the BOM must avoid the AC-input 1600W supply.
Apply C9K-PWR-1600WDC-R in one- or two-PSU C9500-32C designs. For redundant mode, each supply should be connected to a separate power source, and any unused power bay must retain the required blank cover.

- In a C9K-PWR-1600WDC-R vs C9K-PWR-1600WAC-R comparison, the key difference is input power: C9K-PWR-1600WDC-R is the DC-input module and C9K-PWR-1600WAC-R is the AC-input module.
- The C9K-PWR-1600WDC-R difference from C9K-PWR-1600WAC-R also changes connector and cord planning, because the DC model uses the Amphenol C10-638976-000 receptacle with a DC 70A cord rating.
- For buyers comparing C9K-PWR-1600WDC-R vs C9K-PWR-930WDC-R, the supported Catalyst 9500 model is the main comparison point: C9K-PWR-1600WDC-R maps to C9500-32C, while C9K-PWR-930WDC-R maps to C9500-32QC, C9500-48Y4C, and C9500-24Y4C.
- The which model to choose decision should start with the exact chassis, then confirm AC or DC facility power, DC connector requirements, and the Cisco-supported PSU family for that switch.
Selection Guide
1. Start with the chassis model
Choose C9K-PWR-1600WDC-R only for the Catalyst 9500 High Performance C9500-32C model listed with the 1600W DC PSU family.
2. Confirm the DC plant before quoting
Use this SKU when the facility power plan provides Cisco’s documented DC -40 to -72 VDC input range rather than AC input.
3. Keep the connector plan visible
Check the Amphenol C10-638976-000 receptacle and DC 70A cord rating before releasing the BOM to avoid ordering an AC cord or the lower-current 930W DC supply.
4. Decide single module or redundant order
Order the single PSU for a like-for-like replacement, or use the C9K-PWR-1600WDCR/2 redundant line item when the project needs a matched redundant DC power option.
