Description

The PWR-2021-AC-RED is a 2000W hot-swappable AC power supply for the Arista 720XP Series of 1RU campus PoE switches. It supplies both system and PoE power, and supports N+1 redundant power in supported 720XP models. It suits high-power PoE and PoE++ campus access and wiring-closet deployments, including IoT, Wi-Fi access points, cameras and 60-90W powered devices.

This is the front-to-rear (RED) airflow version, with a 2000W output and 80 Plus Platinum efficiency. AC input is accepted at 100-127V (12A), 200-220V (11A) or 220-240V (10A), 50-60Hz, through an IEC-320-C16 inlet. With dual 2000W supplies, PoE budgets reach up to 3584W on the 720XP-96ZC2, 3659W on the 720XP-48ZC2 and 3632W on the 720XP-48TXH-2C-S at typical load.

It is supported in the 720XP-96ZC2, including the -M-S variant, which takes up to four supplies, as well as the 720XP-48ZC2 and 720XP-48TXH-2C-S and -S-5G, which take up to two. Use it with FAN-7000-F front-to-rear fans and do not mix it with rear-to-front (BLUE) units.
