Cisco NCS-5501-GOOGLE= Cloud-Optimized Router
Architecture & Custom Hardware Design T...
The Cisco IR-PWR-G2A-ID= is a high-efficiency AC power supply engineered for Cisco Industrial Routers, including the IR1100 and IR1800 series. Designed to operate in harsh environments, this component ensures uninterrupted power delivery to critical infrastructure like cellular backhaul networks, factory automation systems, and transportation control hubs. Let’s dissect its design philosophy, technical capabilities, and why it outperforms generic power solutions.
Core Design: Built for Industrial Resilience
The IR-PWR-G2A-ID= is more than a power adapter—it’s a mission-critical component for Cisco’s Industrial Router portfolio. Unlike commercial-grade power supplies, it adheres to EN 50155 (railway applications) and IEC 60945 (maritime environments), ensuring reliability under extreme conditions.
Key Technical Specifications
- Input Voltage: 100–240 VAC (50/60 Hz), compatible with global power grids.
- Output Power: 130W continuous, with 90% efficiency to minimize heat dissipation.
- Operating Temperature: -40°C to +70°C (-40°F to 158°F), suitable for unheated outdoor cabinets.
- Protection Features: Overvoltage, short-circuit, and surge protection (up to 2kV).
Why Industrial-Grade Power Matters
In industrial settings, power instability causes 23% of network outages. The IR-PWR-G2A-ID= mitigates this through:
1. Redundant Power Support
When paired with a secondary PSU, the unit enables N+1 redundancy for routers, ensuring zero downtime during power failures. For example, in a traffic management system, this prevents signal controller reboots during voltage dips.
2. Electromagnetic Compatibility (EMC)
Certified to EN 55032 Class A, the PSU suppresses electromagnetic interference (EMI) from heavy machinery, protecting sensitive router electronics.
3. Extended Lifespan
With a MTBF (Mean Time Between Failures) of 500,000 hours, it outlasts standard power supplies by 3x, reducing replacement costs in hard-to-access installations like wind turbines.
Compatibility and Integration
The IR-PWR-G2A-ID= is purpose-built for Cisco’s Industrial Routers, including:
- IR1100-K9: Deployed in smart grid substations and oil pipelines.
- IR1800-K9: Used in mobile LTE/5G backhaul and railway communication systems.
Key Integration Benefits
- Hot-Swappable Design: Replace units without powering down the router, critical for 24/7 operations.
- Cisco IOS-XE Compatibility: Monitors PSU health metrics (voltage, temperature) via CLI or DNA Center.
Deployment Scenarios: Where It Excels
Case 1: Cellular Backhaul in Remote Areas
A telecom operator deployed IR1100 routers with IR-PWR-G2A-ID= units across 200+ microwave tower sites. The PSU’s wide temperature range (-40°C to +70°C) eliminated heater installations in enclosures, saving $4,200 per site annually.
Case 2: Port Automation Systems
In a container terminal, the power supply’s surge protection (2kV) shielded routers from voltage spikes caused by crane motors. The IP40-rated casing resisted saltwater corrosion, achieving 99.999% uptime.
Case 3: Railway Signaling Networks
Integrated with IR1800 routers, the PSU’s EN 50155 compliance ensured seamless operation despite vibrations (5g) from passing trains. Redundant configurations prevented service disruptions during grid fluctuations.
Comparative Analysis: IR-PWR-G2A-ID= vs. Third-Party Alternatives
| Criteria | IR-PWR-G2A-ID= | Generic 130W PSU |
|---|---|---|
| Temperature Range | -40°C to +70°C | 0°C to +40°C |
| Surge Protection | 2kV | 1kV (no industrial certification) |
| EMI Compliance | EN 55032 Class A | Not certified |
| MTBF | 500,000 hours | 150,000 hours |
| Redundancy Support | Yes (N+1) | Limited or none |
While third-party units cost 60% less, the IR-PWR-G2A-ID= reduces TCO by avoiding downtime penalties in regulated industries.
Addressing Critical User Concerns
Q: Can it handle frequent power cycling?
A: Yes. The unit withstands 100,000+ power cycles, unlike consumer PSUs rated for 10,000 cycles. Its inrush current control (<40A) prevents circuit breaker trips during cold starts.
Q: Is it compatible with DC power systems?
A: No—this is an AC-only unit. For DC environments, use the IR-PWR-G2A-DC= variant (48VDC input).
Q: How to troubleshoot a faulty PSU?
A: Cisco IOS-XE provides real-time alerts for:
- Over-temperature conditions (ambient >70°C).
- Output voltage deviations (±5% from 12VDC).
- Fan failures (if applicable to the router model).
Procurement and Installation Guidelines
The “IR-PWR-G2A-ID=” is available through industrial IT suppliers. When ordering, confirm compatibility with your router’s chassis (e.g., IR1100 requires one unit, while IR1800 supports dual PSUs). For hazardous locations, pair with NEMA 4X enclosures to meet ATEX Zone 2 requirements.
Final Evaluation: Why This PSU Is Indispensable for Industrial Networks
Having overseen deployments in mining sites and urban rail systems, the IR-PWR-G2A-ID= isn’t just a component—it’s a strategic asset. Its ability to deliver clean, stable power in environments where temperature swings and electrical noise cripple lesser units translates to measurable ROI. While some may balk at Cisco’s premium pricing, the alternative—unplanned outages, equipment damage, or regulatory fines—proves far costlier. For engineers tasked with maintaining uptime in unforgiving settings, this PSU isn’t optional; it’s insurance.
