NEW Arista FAN-7011M-R Enhanced Speed B-F Fan for 7280R3, 7050X3, 7132LB, 7050X4

The FAN-7011M-R is an enhanced-speed spare fan module for Arista 7050X3 and 7280R3 1RU switches. Enhanced, or medium, speed sits between the standard and high-speed fan options, balancing cooling against noise and power draw.

This version moves air back-to-front (port-side exhaust). Arista also sells the opposite airflow version, the FAN-7011M-F. Pair it with reverse-airflow power supplies, such as blue-handle units, so the whole switch exhausts air on the port side.

All fan modules and power supplies in the switch should move air the same direction. A mismatched part works against the others and can drive up internal temperatures. Match the airflow to whether the switch ports face the cold aisle or the hot aisle.

Do not mix fan speeds without reason, the 7280R3 also uses high-speed FAN-7011H modules, so check what is installed before ordering a replacement. Replacing a failed module promptly restores full cooling headroom, and a spare on the shelf avoids waiting on shipping.

Arista also sells the FAN-7011M-F fan module with the opposite airflow. A seller refurbished FAN-7011M-R is also available.

Because the module is hot-swappable, you can replace a failed fan without powering the switch down. Swap one module at a time so the remaining fans keep cooling the system.

This FAN-7011M-R is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
