Subcategory Breakdown

This category often sits inside broader navigation such as “Cisco Power Supplies,” “Branch Router Power Options,” or “Service Provider DC Infrastructure.” Below are common subcategories and how the PWR-CC1-650WDC fits.

DC vs. AC Power Options for Cisco C8300

Many C8300 deployments start on AC and later migrate to DC when moving from pilot sites to production POPs. The PWR-CC1-650WDC streamlines that transition by supplying the same or greater continuous output with tighter integration into DC plants—ideal for rack-dense installations where dual battery strings and rectifiers are standard. DC versions can also reduce the number of UPS conversions required, further simplifying electrical paths.

Redundant and High-Availability Power Designs

Depending on chassis support, a dual-PSU configuration can provide N+1 redundancy, allowing the router to keep running while one PSU is serviced or replaced. The PWR-CC1-650WDC category includes guidelines for pairing and load-sharing characteristics, cable routing for redundant feeds (A/B), and breaker sizing so that a single failure or planned maintenance event doesn’t compromise service continuity.

Field-Replaceable Unit (FRU) Considerations

The PWR-CC1-650WDC is typically treated as a FRU, enabling quick swap during maintenance windows. Teams standardizing on this unit should maintain a small on-site spare pool to minimize mean time to repair (MTTR). In addition, labeling practices—such as tagging each PSU with feed source A or B and documenting the breaker panel IDs—helps avoid inadvertent cross-feeding or strand loss during site work.

Compatibility with Cisco C8300 Series

The PWR-CC1-650WDC is intended for Cisco C8300 routers that support a 2RU DC power module of this rating. Compatibility typically includes common C8300 variants used for SD-WAN, secure connectivity, and high-throughput edge routing. If you rely on enhanced PoE budgets or numerous service modules, ensure that total system draw plus headroom remains within the 650W envelope or consider redundant PSUs for load sharing. Confirm part number and supported chassis slots before ordering to avoid surprises during installation.

Common Deployment Profiles

• Service Provider POPs using -48V battery plants and rectifiers, where DC feeds are standard, and uptime is paramount.
• Industrial and Utility Substations that prefer DC systems for predictable failover through local battery banks.
• Edge Data Centers and MEC Sites where density and efficiency drive standardization on DC power rails.
• Enterprise Campuses with ISP-grade Facilities consolidating multiple branch WAN functions on a C8300.

Load Planning and Power Budgeting

Power budgeting should tally the base chassis draw, installed network modules, storage, and any integrated power consumers. Add startup inrush considerations and transient spikes. For environments with variable traffic patterns or encryption workloads, assume elevated draw during peak windows. If your architecture mandates hard SLA targets, split power feeds across A/B sources with independent breakers, and use dual PSUs where the chassis supports it for N+1 resilience.

Performance, Efficiency, and Thermal Considerations

DC power conversion efficiency can help reduce the heat footprint in compact racks. A 650W PSU that pairs well with the C8300’s thermal design supports stable operation at load without excessive fan speeds. For sites with limited HVAC, consider:

• Maintaining clear intake and exhaust paths for the chassis.
• Mounting routers in racks with appropriate front-to-back flow alignment.
• Using blanking panels to eliminate hot-air recirculation.
• Monitoring inlet temperatures and setting proactive alerts.

Resilience During DC Plant Events

Telecom DC plants may experience voltage excursions during battery charge cycles or rectifier switchover. The PWR-CC1-650WDC is designed to tolerate typical plant variations within the published input range. However, logging plant events and correlating with router telemetry can help preempt failures. Where available, integrate the router with site DC monitoring to capture feed voltage trends and PSU status over time.

Use Cases and Design Patterns

SD-WAN Edge with Encrypted Multicloud Connectivity

For C8300-based SD-WAN hubs terminating many IPsec or TLS tunnels, stable power is a prerequisite for deterministic performance. The PWR-CC1-650WDC supports sustained CPU and crypto accelerator loads, helping avoid throttling from power constraints. Pairing dual PSUs with dual rectifier strings provides both electrical and path redundancy.

5G and IoT Aggregation

At mobile edge or IoT gateways where space is tight and temperature control is limited, the efficiency benefits of DC power cut down on waste heat. The 650W envelope suits typical interface combinations—cellular, Ethernet aggregation, timing modules—without oversizing the power plant, especially when the chassis does not power large PoE loads directly.

Retail and Branch Consolidation

Enterprises consolidating WAN, security, and application optimization onto a single C8300 can standardize on a DC PSU at sites where DC micro-grids are in place, or where the facility interconnects to a DC bus for energy storage. The result is a resilient branch backbone capable of surviving AC utility disturbances via battery continuity.

Procurement and Lifecycle Strategy

Power components sit at the heart of lifecycle planning. The PWR-CC1-650WDC category includes considerations for spares, RMA, and version alignment so field deployments remain consistent.

Spares and Stocking Levels

For mission-critical sites, a 10–15% spare ratio (or at least one spare per site cluster) is a practical baseline. Spares should be periodically powered and inspected to ensure capacitor health and fan readiness, and firmware (if applicable to the power controller) should align with the production baseline.

RMA and Serial Tracking

Record serial numbers and installation dates in your CMDB. When an RMA is issued, include feed polarity, breaker ratings, and observed LED states in the ticket. This improves root-cause analysis and speeds replacement.

Version Control and Interoperability

When operating in dual-PSU mode, match PSU models and hardware revisions where possible. Mismatched hardware can still function, but identical modules simplify diagnostics and ensure symmetrical load sharing per vendor guidance.

Comparison with Related Cisco Power Supplies

Within the broader Cisco ecosystem, power supplies vary by wattage, form factor, and input type. The PWR-CC1-650WDC’s sweet spot is environments that standardize on DC plants and require a balance of output and efficiency in a 2RU slot. Higher-wattage options may be necessary for expansive PoE or module-heavy builds, while lower-wattage units can fit minimalistic deployments. AC variants are practical for sites without DC infrastructure; however, in telecom-grade facilities, the 650W DC option typically aligns best with operational policies and battery-backed continuity.

Cabling, Breakers, and Grounding

DC power safety depends on proper cable selection and grounding. Use wire gauges sized for the expected continuous load plus overhead. Follow Cisco torque and lug specifications and observe local codes for conductor coloring and labeling. Grounding should connect the chassis to the site earth system via approved bonding points; redundant ground paths are discouraged unless designed in by site engineering, as loops can introduce noise and fault current paths.

A/B Feed Strategy

Many facilities implement A/B feeds from separate rectifier strings or battery banks. In dual-PSU C8300 configurations, assign the PWR-CC1-650WDC modules to opposite feeds. If the chassis supports only a single PSU, you may still run split cabling from dual panels to a single input with diode ORing if supported externally; otherwise, keep the wiring straightforward and compliant with the router’s design.

Labeling and Documentation

Clear labeling of feeds, breaker IDs, and polarity reduces errors during maintenance. Update rack elevation diagrams and single-line electrical drawings after each installation or swap. Store torque values, wire gauges, and part numbers in your MOP template for repeatability across sites.

Sustainability and Energy Efficiency

DC power can reduce conversion losses compared with AC-only deployments, particularly where battery storage is part of the electrical design. The PWR-CC1-650WDC’s efficiency profile contributes to lower operating costs and a reduced carbon footprint, especially at scale across a fleet of edge routers. Heat reductions also lessen strain on HVAC systems, creating a compounding effect in dense racks.

Lifecycle Impacts

Longer PSU life, fewer emergency truck rolls, and standardized spare practices all contribute to sustainability. Using consistent models across sites reduces e-waste by allowing systematic refurbishment and reuse within policy limits.
