NVIDIA Mellanox MTEF-PSF-DC-C 800W DC Power Supply, Rear-to-Front Airflow: This is a hot-swappable DC-input power supply module for NVIDIA Mellanox SwitchX-2 1U switch chassis. It delivers 800W with rear-to-front airflow (equivalent to P2C, Power-to-Connector). It is a field-replaceable PSU module, not a complete switch and not an AC-input unit. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MTEF-PSF-DC-C is sized for SwitchX-2 1U switch platforms that accept the MTEF-PSF series and are deployed in DC-powered data center rows. SwitchX-2 1U switches use redundant N+N PSU bays so a single unit can be replaced while the switch remains in service. The rear-to-front airflow direction must match the airflow of every fan tray and PSU in the same chassis; Mellanox does not support mixed airflow directions in one switch.
Deployment & Use Cases
Replacement PSU for production Mellanox SwitchX-2 1U switches in DC-powered data centers and telecom central offices. Spare PSU inventory for N+N redundancy maintenance. RMA replacement for failed units. Lifecycle refresh for SwitchX-2 deployments where original PSUs have reached end of warranty.
