Description

The PWR-621-AC-RED is a hot-swappable 650W AC power supply module for Arista 720XP and 722XPM 1RU campus PoE switches. It suits campus access and PoE deployments where a spare is needed, where PoE budget is being increased, or where N+1 power redundancy is being added to an existing switch.

This RED-labelled unit has front-to-rear airflow. It delivers 650W output from a 100-240V AC input at 50-60Hz, drawing 8 to 3.5A through an IEC-320-C16 inlet, and is rated 80 PLUS Platinum for efficiency. It is the default power supply on the 720XP-24Y6 and 720XP-24ZY4, and a pair of 650W supplies provides roughly 1110-1135W of PoE budget on the 720XP-48Y6.

For compatibility, Arista lists PWR-621-AC-RED, PWR-621-AC-BLUE, PWR-1021-AC-RED and PWR-1021-AC-BLUE as supported AC supplies on the 720XP and 722XPM. Pair this unit with FAN-7000-F fan modules for front-to-rear airflow and do not mix airflow directions. A single installed supply must sit in power supply bay 1. It is not intended for the 720XP-96ZC2 or 720XP-48TXH-2C-S.

FAQs

Q: Which switches use the PWR-621-AC-RED?
A: It is supported in Arista 720XP and 722XPM Series 1RU campus PoE switches. It is not intended for the 720XP-96ZC2 or 720XP-48TXH-2C-S.

Q: What power cord does it need?
A: It has an IEC-320-C16 input inlet, so it requires an IEC-320 compliant power cord suited to your region.

Q: Can I mix it with a PWR-621-AC-BLUE?
A: No. Airflow directions must not be mixed. The RED unit is front-to-rear and should be paired with FAN-7000-F fan modules.

Q: Can I run it as the only power supply?
A: Yes, the switch supports single or redundant supplies. If only one supply is installed it must go in power supply bay 1.

Q: How much PoE budget does it provide?
A: A single 650W supply gives about 583W typical PoE on the 720XP-24Y6, while two supplies give roughly 1110-1135W on the 720XP-48Y6.
