Cisco PWR-CC1-400WDC
Cisco C8300 1RU DC Power supply
Product Highlights
Deploying enterprise edge routers in DC-powered environments — telecom central offices, remote service-provider facilities, or sites without reliable AC mains — demands a power supply purpose-built for those conditions. The Cisco PWR-CC1-400WDC is a 400-watt DC power supply module designed specifically for the Cisco Catalyst 8300 Series 1RU Edge Platforms.
Accepting a wide –40V to –72V DC input range, this PSU integrates seamlessly with standard –48V telecom battery plants and DC distribution systems. It delivers a clean, regulated 12V output at up to 33.5A, ensuring stable operation of the C8300 chassis and its installed modules. With 85% power efficiency, it minimizes thermal load and energy costs in facilities where every watt counts.
The PWR-CC1-400WDC is a hot-swappable, field-replaceable plug-in module that supports 1+1 redundancy in load-sharing mode when paired with a second power supply. This means you can replace a failed unit or perform planned maintenance without interrupting network services — critical for SD-WAN edge nodes and branch routers that must maintain continuous uptime. Compatible with the C8300-1N1S-4T2X, C8300-1N1S-6T, and select C8200 platforms, it is the go-to DC power option for Cisco's next-generation edge routing infrastructure.
Features & Benefits
Telecom-Grade DC Input
The PWR-CC1-400WDC accepts a –40V to –72V DC input range, making it fully compatible with standard –48V telecom battery plants and centralized DC power distribution systems. This wide input tolerance ensures stable operation even during battery discharge cycles or voltage fluctuations common in service-provider and central-office environments.
Hot-Plug Redundancy
Designed as a hot-swappable plug-in module, this power supply can be inserted or removed without powering down the chassis. When paired with a second PSU, the two units operate in 1+1 load-sharing mode, providing automatic failover and ensuring uninterrupted service during maintenance or a PSU failure.
High Efficiency Operation
At 85% power efficiency, the PWR-CC1-400WDC converts more input power into usable output while generating less waste heat. This reduces cooling requirements and energy costs — a meaningful advantage in dense deployments or facilities with constrained thermal budgets.
Field-Replaceable Design
As a field-replaceable unit (FRU), the PWR-CC1-400WDC simplifies spares management across distributed branch and edge sites. Network teams can stock a single DC PSU SKU and quickly swap units on-site, minimizing mean time to repair (MTTR) and reducing the need for specialized depot service.
Deployment Scenarios
Telecom Central Office / Service Provider POP
Central offices and points of presence typically run on –48V DC battery plants. The PWR-CC1-400WDC's –40V to –72V input range integrates directly with these DC distribution systems, powering Catalyst 8300 SD-WAN edge routers without requiring AC inverters or additional power conversion equipment.
Remote Branch with DC Power Infrastructure
Remote or industrial branch sites that rely on DC power sources — such as solar-battery systems or DC microgrids — benefit from a native DC power supply. The PWR-CC1-400WDC eliminates the AC conversion step, improving overall power-path efficiency and reducing points of failure.
Redundant PSU Upgrade or Replacement
For existing Catalyst 8300 1RU deployments that need a DC power supply replacement or a second PSU for 1+1 redundancy, the PWR-CC1-400WDC serves as a hot-swappable drop-in unit. It enables non-disruptive upgrades and ensures continuous operation during planned maintenance windows.

Compatibility Notes
Compatible Platforms
The PWR-CC1-400WDC is designed for the following Cisco Catalyst 8300 and 8200 Series Edge Platforms:
- C8300-1N1S-4T2X (1RU, 2×10G + 4×1G WAN)
- C8300-1N1S-6T (1RU, 6×1G WAN)
- C8200-1N-4T
- C8200L-1N-4T
- C8200-UCPE-1N8
Note: This is a 1RU-form-factor power supply. It is not compatible with the 2RU C8300-2N2S models, which use the larger 650W DC supply (PWR-CC1-650WDC). The power supplies between 1RU and 2RU chassis are not interchangeable.
Wiring Requirements
- DC input connector: Terminal block (2-wire screw-type)
- Power cord rating: 15A, #14 AWG wire
- Input polarity (facing unit, left to right): Positive (+), Negative (–)
