PWR-1511-AC-RED Arista 7280r3 1000W 200-240V Airflow Switch Power Supply.

The PWR-1511-AC-REDARISTA 7280r3 1000W 200–240 V AC Airflow Switch Power Supply offers enterprise-grade reliability and high-performance power delivery ideal for demanding network environments. This dedicated category includes the core unit and compatible sub‑variants tailored to support high-capacity airflow‑optimized switches such as the REDARISTA 7280r3 series. Engineered to deliver continuous 1000 W power from a universal 200–240 V AC source, this power module ensures seamless data center operations and minimized downtime.

Airflow‑Optimized Design

The airflow switch power supply is engineered with ventilation patterns and internal airflow paths matching the REDARISTA 7280r3 chassis architecture. This design minimizes turbulence and enhances heat dissipation, enabling reliable operation under sustained high-output conditions.

High Efficiency and Energy Savings

Rated for continuous 1000 W output, the PWR‑1511‑AC‑REDARISTA module operates with high efficiency—typically exceeding 90 %—across the 200–240 V AC input range. This efficiency reduces energy waste, lowers cooling costs, and supports green data center initiatives that align with modern ESG requirements.

Robust Voltage Compatibility

Wide input range (200–240 V AC) ensures compatibility with global primary power sources. Whether deployed in North America, Europe, Asia or telecom‑grade facilities, this module accommodates line voltage variation while delivering stable, certified power to network equipment.

Safety and Compliance

Certified for global standards including UL, CE, FCC, and optional IEC 60950‑1 / IEEE 802.3 compliance when used in specific switch models. This ensures not only performance, but also electrical safety and electromagnetic compatibility in enterprise environments.

Redundancy and Hot-Swap Capability

The PWR‑1511 module supports full N+1 redundancy. In multi‑power‑supply configurations, one module can fail or be removed without interrupting switch operation. Ideal for live maintenance and high‑availability network designs.

Slide‑in Hot‑Swap Mechanism

Equipped with a robust guide rail and latch mechanism, the power supply slides into the chassis effortlessly. The intuitive design ensures module alignment, mechanical stability, and electrical contact assurance—reducing installation time and error risk.

LED Status Indicators

Two LEDs provide clear visual feedback:

• Green: Operating normally and delivering full 1000 W output.
• Amber/Red: Indicates module fault, input voltage issue, or temperature warning.

Compatibility and Labeling

Each module includes a vibration‑resistant barcode and serial number for inventory tracking, and is labeled with clear input/output specs. Mounting slots and connector interfaces match manufacturer‑specified tolerances for the REDARISTA 7280r3 chassis.

Performance Features

Power Regulation and Stability

Incorporated voltage regulation circuitry ensures clean, ripple‑free 1000 W output, protecting sensitive switch electronics. Tight voltage tolerances (± 1 %) account for AC line fluctuations typical in telecom and industrial power systems.

Thermal Protection

Internal over‑temperature sensors actively monitor component heat. In the event of excessive thermal rise, the power supply initiates automatic power descaling or module shutdown, safeguarding both itself and the switch chassis from damage.

Overcurrent and Short‑Circuit Safeguards

Built‑in overcurrent protection triggers immediate shutdown in case of fault conditions. The module incorporates fast‑acting fuses and electronic sensing circuits to isolate faulted units, protecting the switch from downstream damage.

Field‑Replaceable Unit (FRU)

Designed as a FRU, the power module can be quickly replaced during scheduled service windows or emergency interventions, minimizing network downtime. Spare modules can be stored on-site for rapid swap‑out.

Firmware Upgrade Paths

In concert with the REDARISTA chassis firmware, the PWR‑1511 supports integrated firmware updates that may optimize power‑on self‑test sequences, LED diagnostics, or thermal profiles. Updates are applied via the switch’s management interface.

Lifecycle and Reliability Metrics

Rated for MTBF (Mean Time Between Failures) exceeding 100,000 hours (approximately 11 years) under normal operating conditions. Designed with electrolytic‑free capacitors and industrial‑grade components for prolonged reliability in intense data center climates.

Match Wattage and Voltage Compatibility

Ensure that the module supports 1000 W continuous output and matches your facility’s 200–240 V AC supply. Mismatches here can cause undervoltage issues or performance limitations.

Airflow Direction and Chassis Alignment

Confirm airflow direction matches your rack‑layout cooling design—front‑to‑back or back‑to‑front—as mismatched airflow can impair cooling efficiency.

Check Certification and Approval Requirements

If deploying in regulated industries or international facilities, verify that the module has the necessary certifications (e.g. CE, UL, RoHS, CCC) for your region to avoid compliance issues.

Redundancy Planning

Consider purchasing spare modules to support N+1 redundancy. This approach maintains switch uptime during replacement or unexpected failure.

Availability of Firmware

When choosing products in this category, confirm that your switch firmware supports the power module (for diagnostics, LED behavior, thermal control) and that documentation/support is available in your region.
