Description

The PWR-621-AC-RED is a 650W AC power supply module for Arista 720XP 1RU campus PoE switches, with front-to-rear airflow (red handle). It is 80+ Gold rated and supports N+1 redundant power configurations, making it suited to both spare-unit stocking and redundancy upgrades in campus access deployments.

The module accepts 100-240V AC input over an IEC-320-C16 connector and is compatible with the 720XP-48Y6, 720XP-24Y6, 720XP-48ZC2 and 720XP-24ZY4. It is hot-swappable and field-replaceable, and load-sharing supplies draw from a common PoE power bank within the switch. For rear-to-front airflow, the BLUE model (PWR-621-AC-BLUE) is the alternative.

FAQs

Q: Which Arista switches is the PWR-621-AC-RED compatible with?
A: It is compatible with the Arista 720XP-48Y6 and 720XP-24Y6 (1G platforms) and the 720XP-48ZC2 and 720XP-24ZY4 (mGig platforms).

Q: What airflow direction does the PWR-621-AC-RED provide?
A: It provides front-to-rear airflow, identified by the red handle. For rear-to-front airflow, the BLUE model PWR-621-AC-BLUE is the alternative.

Q: Can I mix airflow directions in the same switch?
A: The power supplies in a chassis should match the airflow direction of the switch, so pair the RED (front-to-rear) module with a front-to-rear configuration. Use the BLUE model only in rear-to-front deployments.

Q: Does this power supply support redundant power?
A: Yes. It supports N+1 redundant power configurations in 720XP switches, and the load-sharing supplies share a common PoE power bank within the switch.

Q: Is the PWR-621-AC-RED hot-swappable?
A: Yes. It is a hot-swappable, field-replaceable module, so a failed supply can be replaced without taking the switch offline when a redundant supply is installed.

Q: What input power does it require?
A: It accepts 100-240V AC at 50-60 Hz through an IEC-320-C16 input connector, with an input current of 8 - 3.5 A.
