Description

The Arista PWR-460AC-R is a 460W AC hot-swappable power supply module with rear-to-front airflow, designed for Arista 7124SX, 7050 and 7048-A switches. It suits data centre top-of-rack deployments where a failed or spare unit needs to be swapped without taking the switch offline, and where airflow must match a rear-to-front cooling layout.

The module accepts 100-240V AC input at 50/60 Hz through an IEC 320-C13 connector and supports 1+1 redundant operation, with two hot-swap power supplies per switch. For correct cooling, pair it with rear-to-front FAN-7000-R fan modules so the whole chassis draws air in the same direction.

Features

- Hot-swappable, 1+1 redundant power supply for 7050 Series switches
- Colour-coded PSU, common to Arista 1RU devices
- Rear-to-front cooling option, matched with FAN-7000-R fan modules
- Spare or replacement module for Arista 7124SX, 7050 and 7048-A switches
