Description

The PWR-1511-DC-RED is a 1500W DC-input, DC-output hot-swap power supply module for Arista 1RU data centre switches. It suits data centre and telco or central-office deployments that run on a -48 VDC power plant and need redundant, hot-swappable DC power for leaf, spine and 100G or 400G fixed switches.

This is the DC input, Front-to-Rear (RED) airflow variant. It accepts a -48 to -60 VDC feed at up to 35.2 A (at -48 V) through AWG #6 maximum terminals, and delivers 1500W output at a typical efficiency of 92%. The 1RU, 73.5mm module belongs to the PWR-1511 family, which shares a common form factor across AC and DC and across RED and BLUE airflow versions.

It is listed as a supported power supply for the Arista 7050X4, 7060X5, 7280R3 and 7280R3A series, as well as the 7050X3 MACsec series. Airflow must match the fan modules and the chassis airflow direction, with RED meaning front-to-rear, and airflow directions should not be mixed within one chassis.

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

FAQs

Q: Does this power supply need a licence?
A: No licence is required for the power supply itself. Feature licences for EOS depend on the host switch platform, for example LIC-FIX-3 or LIC-FIX-4 on the 7060X5.

Q: What power feed does it need?
A: It takes a -48 to -60 VDC input at up to 35.2 A (at -48 V), connected through AWG #6 maximum terminals. It delivers 1500W output.

Q: Which Arista switches is it compatible with?
A: It is listed as a supported power supply for the 7050X4, 7060X5, 7280R3 and 7280R3A series, including the 7280CR3A-72 and 7280CR3A-32S, and the 7050X3 MACsec series.

Q: Can I mix airflow directions in one chassis?
A: No. The RED variant provides front-to-rear airflow and must match the fan modules and chassis airflow direction. Do not mix airflow directions in one chassis.

Q: What is the difference between the RED and BLUE variants?
A: RED provides front-to-rear (forward) airflow, while BLUE provides reverse airflow. Both share the same 1RU, 73.5mm form factor within the PWR-1511 family.
