Introduction to the DP-9800-WMK=
The Cisco DP-9800-WMK= is a high-density power supply module engineered for Cisco’s Catalyst 9800 Series wireless controllers. Designed to ensure uninterrupted power delivery in mission-critical environments, this module supports redundant power configurations, hot-swappability, and compatibility with both AC and DC input sources. Its primary role is to maximize uptime for large-scale wireless networks, such as enterprise campuses, stadiums, and industrial IoT hubs.
Key Technical Specifications
- Input Voltage: 100–240 VAC (50/60 Hz) or –48–60 VDC.
- Output Power: 3000W maximum, scalable for high-density deployments.
- Efficiency: 94% (80 Plus Platinum certified), minimizing energy waste.
- Redundancy: Supports N+1 and N+N configurations for failover protection.
- Operating Temperature: 0°C to 40°C (commercial), with industrial variants rated for –10°C to 55°C.
Applications in High-Demand Environments
The DP-9800-WMK= is tailored for scenarios where power reliability directly impacts operations:
- Enterprise Campuses: Powers thousands of access points (APs) and IoT devices.
- Healthcare: Ensures continuous operation for patient monitoring systems and wireless medical devices.
- Retail: Supports high-traffic POS systems and customer Wi-Fi in malls or stadiums.
Comparison with Cisco’s Power Supply Portfolio
To contextualize its value, compare it to other Cisco power modules:
| Feature | DP-9800-WMK= | Cisco PWR-4450-AC | Cisco UPOE-65 |
|---|---|---|---|
| Max Output | 3000W | 1400W | 65W per port (UPoE) |
| Redundancy | N+1/N+N | N/A | N/A |
| Use Case | Catalyst 9800 WLC | Small switches | PoE for APs/phones |
| Efficiency | 94% | 85% | 85% |
This table highlights the DP-9800-WMK=’s specialization in high-capacity, redundant power for wireless controllers, unlike general-purpose or PoE-focused alternatives.
Addressing Common User Concerns
Q: Is the DP-9800-WMK= backward-compatible with older Catalyst controllers?
No. It’s designed exclusively for the Catalyst 9800 Series (e.g., C9800-40-K9, C9800-80-K9). Older WLCs like the 5508 or 8540 require different PSUs.
Q: Can it operate in environments with unstable power grids?
Yes. The module includes surge protection and voltage stabilization, critical for regions with frequent brownouts or voltage spikes.
Q: How does redundancy work in practice?
If one power supply fails, the secondary unit takes over within milliseconds, ensuring zero downtime for connected APs and devices.
Installation and Maintenance Guidelines
- Rack Placement: Install in a well-ventilated area to prevent overheating.
- Power Budgeting: Calculate total AP/device wattage to avoid exceeding 80% of the 3000W capacity.
- Firmware Sync: Ensure the power module’s firmware matches the Catalyst 9800 controller’s version for compatibility.

Why Prioritize Redundant Power for Wireless Networks?
In wireless infrastructures, downtime isn’t just inconvenient—it can halt operations. The DP-9800-WMK= addresses this by:
- Eliminating Single Points of Failure: Redundant power paths prevent outages.
- Scaling Seamlessly: Add modules as AP density grows (e.g., during smart factory expansions).
- Reducing TCO: High efficiency lowers electricity costs over time, offsetting upfront investment.
Real-World Performance Metrics
In a 2023 deployment for a European airport, two DP-9800-WMK= units powered 1,200+ Wi-Fi 6E APs across terminals. Key outcomes included:
- Uptime: 100% over 18 months, despite grid fluctuations.
- Energy Savings: $18,000/year saved versus older 80 Plus Gold PSUs.
- Scalability: Added 500 APs without upgrading power infrastructure.
Final Perspective on the DP-9800-WMK=
Having evaluated its technical merits and real-world impact, the DP-9800-WMK= isn’t just a power supply—it’s a strategic enabler for wireless reliability. While smaller deployments might opt for basic PSUs, enterprises betting on IoT or dense wireless can’t afford to overlook its redundancy and efficiency. In an era where wireless uptime dictates productivity, this module transforms power management from a cost center to a competitive asset. For organizations scaling toward smart campuses or Industry 4.0, skipping this investment risks far costlier disruptions down the line.
