NEW Arista PWR-1900AC-R 1900W AC B-F (Blue) Switch Power Supply for 7260CX 7280R

The PWR-1900AC-R is a spare 1900W AC power supply for Arista 7260CX, 7280R and 7368X Series switches, including the 2RU 7280CR models. Its high output suits the larger 100G platforms in those families.

Input is high-line only, 200 to 240V AC. It will not run on 120V, so make sure the rack has 208V or 230V PDUs and suitable cords before installing.

This version moves air back-to-front (port-side exhaust). Arista also sells the opposite airflow version, the PWR-1900AC-F. Match the supply to every fan module in the switch and to the rack's hot and cold aisles, since a supply pushing air the wrong way works against the fans.

Arista rates efficiency at 93% typical, Platinum level. With two supplies installed, a spare lets a failed unit be replaced while the switch runs on the other one. Read the part number on the installed supplies before ordering, so the airflow and wattage of the spare match what is already in the switch.

Arista also sells the PWR-1900AC-F power supply with the opposite airflow. A seller refurbished PWR-1900AC-R is also available.

This PWR-1900AC-R is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
