Arista 500W AC 1RU Power Supply, Front-to-Rear Airflow
PWR-511-AC-RED · Refurbished · 1 year warranty
Quantity (units)
Overview
Airflow direction is encoded in the part number of the Arista 500W AC 1RU Power Supply, Front-to-Rear Airflow (PWR-511-AC-RED): the RED suffix goes with front-to-rear airflow, and the title states it explicitly. That matters because a switch and its power supplies must move air in the same direction, or the cooling plan inside the chassis stops working.
Electrically it is a 500W unit with AC input, built in the 1RU power supply form. Verify the compatibility against your switch before ordering. Arista labels its supplies by airflow, and swapping a front-to-rear unit into a rear-to-front system is a classic mistake.
Users buy a part like this to replace a failed supply or to fill an empty power supply slot. Two matching supplies in the same switch give a switch its power redundancy, provided the switch supports it.
No alternative part numbers are recorded for it.
The PWR-511-AC-RED is offered new and refurbished, each with a warranty of 1 year or 3 years.
