Description

This 460W AC power supply is a hot-swappable module for selected Arista 7000 Series 1RU fixed data-centre switches, including the 7124SX, 7050 and 7048-A ranges. It suits teams that need a spare unit or a second supply for a 1+1 redundant configuration in a top-of-rack or leaf switch.

The module delivers 460W from an AC input of 100-240V AC at 50/60Hz, drawing 2.2-5.3A, and connects through an IEC 320-C13 inlet. The R suffix denotes rear-to-front airflow, so it suits racks where cool air enters at the rear of the switch and exhausts at the front. The airflow direction of every power supply must match the switch fan modules and the other supply in the chassis.

For compatibility, it pairs with rear-to-front fan modules such as FAN-7000-R. The front-to-rear equivalent is PWR-460AC-F, and DC versions are available as PWR-460DC-F and PWR-460DC-R.

FAQs

Q: Which Arista switches does this power supply fit?
A: It is listed as a spare for the Arista 7124SX, 7050 and 7048-A series switches, and is also commonly used in the 7150 series.

Q: Does the airflow direction need to match the rest of the switch?
A: Yes. The rear-to-front airflow of this supply must match the switch fan modules, such as FAN-7000-R, and the other power supply in the chassis.

Q: Is there a front-to-rear version?
A: Yes. The front-to-rear equivalent is PWR-460AC-F. DC models are available as PWR-460DC-F and PWR-460DC-R.

Q: What AC input does it need?
A: It accepts 100-240V AC at 50/60Hz, drawing 2.2-5.3A, through an IEC 320-C13 connector.

Q: Can it be used for redundancy?
A: Yes. The host switches use two hot-swap power supplies in a 1+1 redundant configuration, so this module can serve as the second supply.
