Description
Description
This is a 700W DC hot-swappable power supply module for Arista 720XP series 1RU campus PoE switches. It suits DC-fed wiring closets, branch sites and telco-style environments where a 720XP switch needs a DC input or extra PoE budget, and it can be paired with a second unit for redundancy.
The module accepts a -48 to -60 V DC input at 25A and delivers 700W of output at 90% efficiency. A 30A branch-circuit over-current protection requirement applies. Wiring uses AWG #14 to #12 conductors on twin #10 studs with a dual-hole lug. It is the front-to-rear airflow (-RED) variant, so it matches FAN-7000-F fan modules in the same chassis. It is the higher-capacity option to the 500W PWR-521-DC-RED for PoE-heavy 720XP configurations.
It is intended for the 720XP 1RU family, including the 720XP-48Y6, 720XP-24ZY4 and 720XP-96ZC2. Each 1RU switch takes up to two power supplies, and the 720XP-96ZC2 takes up to four. It is not interchangeable with the 650W AC or 1050W AC units, and it should not be mixed with supplies of a different airflow direction.

FAQs
Q: Does this power supply need a licence?
A: No licence is required for the power supply itself. The host 720XP switch uses EOS licence groups and CloudVision licence groups.
Q: What DC supply does it need?
A: It takes a -48 to -60 V DC input at 25A and needs a 30A branch-circuit over-current protection. It delivers 700W of output.
Q: Which switches is it compatible with?
A: It is for the Arista 720XP 1RU campus PoE family, such as the 720XP-48Y6, 720XP-24ZY4 and 720XP-96ZC2. Check the datasheet power supply rows to confirm the exact switch model.
Q: Which fan modules should I use with it?
A: Use FAN-7000-F fan modules, which share the front-to-rear (-RED) airflow direction. Do not mix with power supplies of a different airflow.
Q: Can I use it with the AC power supplies?
A: It is not interchangeable with the 650W AC or 1050W AC units. Match supplies of the same airflow direction in one chassis.
