Arista PWR-1022-AC-RED | 1050W PoE v3 Power Supply, Front-to-Rear Airflow

Q: Which Arista switches are compatible with the PWR-1022-AC-RED power supply?
A: This power supply is designed for the Arista CCS-720XPM and CCS-720XDM series 1RU campus switches. It provides 1050W of PoE v3 power delivery with front-to-rear airflow cooling.

Q: What does the red handle on this power supply indicate?
A: The red handle indicates front-to-rear airflow direction. This must match the airflow direction of your switch chassis and fan modules to ensure proper cooling and optimal performance.

Q: Can I install this power supply while the switch is running?
A: Yes, the PWR-1022-AC-RED is hot-swappable, allowing you to install or replace it without powering down the switch. This is particularly important in redundant power configurations for maintaining continuous uptime.

Q: What is the difference between PWR-1022-AC-RED and PWR-1021-AC-RED?
A: The PWR-1022-AC-RED is a PoE v3 power supply designed for the 720XPM/XDM series, while the PWR-1021-AC-RED is for the 720XP series. Both provide 1050W output, but the PWR-1022-AC-RED features enhanced PoE v3 capabilities for the newer campus switch models.

Q: How many power supplies does my CCS-720XPM switch require?
A: CCS-720XPM switches can operate with a single power supply, but deploying two power supplies is recommended for N+1 redundancy. This ensures continued operation if one power supply fails, critical for campus networks supporting PoE devices like access points and IP phones.
