MTEF-PSR-AC-E, Mellanox Power Supply, 550W AC/C2P Airflow/For SN3420/Power cord included

The Mellanox (NVIDIA Networking) NVIDIA Mellanox MTEF-PSR-AC-E is a dedicated enterprise-class power supply module designed as an accessory for NVIDIA Mellanox SN3420 series data center switches. This hot-swappable PSU delivers stable AC power for high-density Layer 2/Layer 3 switching environments in Asia, Europe, Africa, and North America, helping distributors, system integrators, and end users keep core network services online. With 550 W power capacity and C2P (cold-to-hot, front-to-rear) airflow, the NVIDIA Mellanox MTEF-PSR-AC-E supports efficient cooling in standard front-to-back data center layouts and enterprise equipment rooms. As a field-replaceable module, it allows fast on-site replacement without taking the SN3420 switch out of service, which helps reduce downtime and simplifies maintenance planning for multinational deployments.

This power supply module is engineered specifically for the NVIDIA Mellanox SN3420 series switch platform, ensuring electrical and mechanical compatibility when installed according to system documentation. The AC power input design makes it suitable for common regional power standards, while the included power cord helps distributors and SMB integrators speed up installation and shorten delivery-to-go-live time. The C2P airflow direction of the NVIDIA Mellanox MTEF-PSR-AC-E aligns with cold-aisle/hot-aisle configurations widely used in colocation facilities and enterprise data centers, helping maintain stable operating temperatures and prolonging switch lifespan.

For network planners and resellers, the NVIDIA Mellanox MTEF-PSR-AC-E offers a clear, predictable option for building redundant power configurations on SN3420 switches. Using dual PSUs, customers can increase power resilience and support critical workloads such as virtualized servers, storage, or top-of-rack aggregation links without redesigning rack power distribution. Field engineers can replace the module on-site while the switch remains in operation, which is especially valuable for distributed branch networks and latency-sensitive environments.
