SMC 644W Redundant Power Supply

When uptime is a non-negotiable requirement for your network, the SMC 644W Redundant Power Supply stands as a dependable cornerstone for power resilience. This unit is engineered to deliver up to 600 watts of backup power to four switches in the event of an AC loss or a failure within an internal power supply. The combination of a robust 644W rating and intelligent protections keeps your critical networking devices online, minimizes downtime, and reduces the risk of cascading outages across your data center, campus network, or enterprise rack. With a focus on reliability, efficiency, and straightforward integration, the SMC 644W RPS helps you maintain performance, protect valuable equipment, and simplify power management in demanding environments.

• Up to 600W of backup power to four switches during AC loss or internal power supply failure, ensuring critical network paths remain active and data flows uninterrupted when main power is interrupted.
• Redundant architecture with automatic protection keeps power available to essential devices even if one path experiences a fault, supporting continuous operation and minimizing downtime in busy server rooms and data centers.
• Thermal overload protection detects rising temperatures and responds to prevent overheating, preserving performance, extending component life, and reducing the risk of thermal-related outages in hot hardware environments.
• Over-voltage protection monitors input conditions and isolates or shuts down a compromised channel to shield sensitive switches and networking gear from voltage spikes and transients common in legacy or crowded power environments.
• Designed for easy integration into standard 19-inch racks with clearly labeled outputs and intuitive status indicators, making deployment, maintenance, and monitoring straightforward for IT staff and technicians.

How to install SMC 644W Redundant Power Supply

• Power down the equipment and confirm that the primary power sources for the rack are safely de-energized before installing the redundant power supply.
• Mount the SMC 644W Redundant Power Supply into a standard 19-inch rack using the provided mounting hardware, ensuring stable support and proper ventilation.
• Connect the four output channels to the corresponding switches or devices that require backup power, using appropriate power cables and ensuring a clean, organized cable layout to promote airflow.
• Attach the input power sources according to your facility’s design, typically routing one feed as a primary and the other as a redundant supply, following your data center’s electrical best practices.
• Power on the unit and verify operation by observing the status indicators and ensuring each connected switch receives stable power during test conditions that simulate AC loss.
• Document the installation, label cables clearly, and implement routine monitoring to quickly detect any changes in power status, temperature, or output loads to maintain optimal reliability.
