Arista FAN-7100-R Back-to-Front Air Switch Fan Module for 7048 and 7100 Series

The FAN-7100-R is a spare fan module for the Arista 7100 Series and the 7048T. It fits the 7124S, 7148S, 7148SX, 7120T-4S and 7140T-8S.

One part number covers all six of these switches, so a small stock of spares can support a group of them in the same room. Fan modules are among the simplest parts to swap in the field, and a spare on the shelf avoids a wait for shipping.

This version moves air back-to-front (port-side exhaust). Arista also sells the opposite airflow version, the FAN-7100-F. All fan modules and power supplies in a switch should move air in the same direction, matched to whether the switch ports face the cold aisle or the hot aisle.

Check the installed fans and power supplies before ordering, so the spare matches. A failed module should be replaced promptly to restore full cooling headroom. Keeping a spare on hand avoids waiting on shipping when an alarm comes up.

Arista also sells the FAN-7100-F fan module with the opposite airflow.

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 seller refurbished FAN-7100-R is tested, working, and covered by the NetworkTigers one-year warranty.
