Description

The Arista PWR-1011 BLUE is a 1RU, 73.5mm-wide, 1000W DC-input hot-swap power supply module for selected Arista data centre switches. It is the reverse (rear-to-front) airflow version, identified by its blue handle, and suits redundant DC-powered or telco-style data centre deployments.

It accepts a -48 to -60 VDC input with a typical input current of 23A maximum at -48V, and delivers 1000W of output power at 94% typical efficiency. The input connector accepts wire up to AWG #6. As a DC, 1000W, reverse airflow, 73.5mm unit, it is distinct from the RED forward airflow variant of the same PWR-1011 family.

The module is listed as a supported power supply for the Arista 7050X3, 7280R3 and 7280R3A series. Airflow must match the switch fan tray and the other power supply fitted, so the BLUE reverse airflow supply should be paired with reverse airflow fans and a second BLUE module for redundancy.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: What input power does this supply need?
A: It runs from a DC feed of -48 to -60 VDC. Typical input current is 23A maximum at -48V, and the input connector accepts wire up to AWG #6.

Q: Which Arista switches does it work with?
A: It is a supported power supply for the Arista 7050X3, 7280R3 and 7280R3A series.

Q: What is the difference between the BLUE and RED versions?
A: BLUE is the reverse airflow (rear-to-front) version and RED is forward airflow (front-to-rear). The two are otherwise the same 1000W DC, 73.5mm module.

Q: Do the airflow directions need to match?
A: Yes. The airflow of the power supply must match the switch fan tray and the other power supply installed, so use BLUE supplies with reverse airflow fans.

Q: Can it be hot-swapped for redundancy?
A: Yes. The module is hot-swappable and supports redundant operation alongside a second matching supply.
