UCSC-HSLP-M6= Hyperscale Power Delivery Modul
Strategic Role in Cisco’s Power-Optimized Infra...
Product Overview and Design Objectives
The Cisco PWR-66W-I-DC= is a 66-watt DC power supply engineered for Cisco Industrial Ethernet switches and IoT gateways operating in harsh environments such as factories, oil refineries, and outdoor telecom sites. Designed to deliver reliable power under extreme conditions, it features:
- Wide Input Voltage Range: 12–48V DC (±20% tolerance), compatible with battery-backed and unstable DC sources.
- Ruggedized Construction: IP40-rated enclosure with MIL-STD-810H certification for shock/vibration resistance.
- Extended Temperature Support: Operates in -40°C to 75°C environments (IEC 60068-2-1/14).
This PSU is optimized for Cisco IE 3400 Series switches and Cisco IR1100 routers, providing stable power for PoE+ devices, sensors, and edge compute modules in OT/IT converged networks.

Key Use Cases and Deployment Scenarios
1. Industrial IoT and Factory Automation
A German automotive manufacturer deployed 50 PSUs in Cisco IE 3400 switches to power 200+ PROFINET sensors in robotic assembly lines, surviving 15G mechanical shocks and coolant exposure.
2. Renewable Energy Site Power Backup
A Canadian solar farm used the PSU with 48V LiFePO4 batteries to maintain Cisco IR1101 routers during grid outages, achieving 99.9% uptime in -30°C winter conditions.
3. Railway Signaling Networks
A European rail operator integrated the PSU into Cisco ESS-3300 switches for CBTC (Communications-Based Train Control) systems, meeting EN 50155 standards for vibration and EMI.
Addressing Critical Customer Concerns
Q: Can it power PoE devices like IP cameras?
Yes, when paired with Cisco UPOE+ modules, it supports 30W per port for devices like Cisco IP CCTV cameras or Wi-Fi 6 access points.
Q: How to mitigate voltage drops in long cable runs?
Use 14 AWG cabling for runs >10 meters and enable Cisco Voltage Boost in IOS-XE to compensate for ≤3V drops.
Q: Is maintenance required for fanless models?
- Annual: Inspect thermal pads for degradation (replace if hardness exceeds Shore 60A).
- Biannual: Clean ventilation slots with Cisco CAB-CLN-IP40 anti-static brushes.
Installation and Optimization Best Practices
- Grounding Compliance:
- Connect chassis ground via 12 AWG wire (≤0.1 Ω resistance) to meet NEC 250.122.
- Thermal Management:
- Maintain ≥25 mm clearance around vents in 75°C environments.
- Input Filtering:
- Install Cisco CAB-FILTER-12V= EMI filters if DC source exceeds EN 61000-3-12 harmonics.

Operational Insights from Harsh Environments
Two lessons from global deployments stand out:
- Cold Starts Are the Silent Killer: A Siberian mining company reduced PSU failures by 70% by preheating units to -20°C before powering on in -50°C winters.
- Dust Doesn’t Discriminate: A UAE oil refinery avoided 14 outages/year by implementing biweekly vent cleaning—proving even IP40-rated gear needs proactive care.
In an age where edge computing pushes infrastructure to extremes, the PWR-66W-I-DC= embodies a paradox: the harsher the environment, the more critical the basics become. While engineers chase AI-driven predictive maintenance, this PSU’s value lies in its unyielding simplicity—no algorithms, just electrons flowing reliably where others fear to go. Sometimes, innovation isn’t about what’s new, but what endures.
