Description

The PWR-1011-DC-RED is a 1RU, hot-swappable DC power supply module for selected Arista 7000-series fixed-configuration data centre switches. It suits data centre and telco or central-office deployments that run on -48V DC power plants and need front-to-rear airflow, from cold aisle to hot aisle.

This module delivers 1000W of output from a -48 to -60 V DC input, drawing up to 23A at -48V. DC wiring connects through terminal lugs up to AWG #6. It is a 1RU unit, 73.5mm wide, with typical efficiency of 94% on the 7050X3 datasheet. The red handle identifies front-to-rear (forward) airflow, so it must be paired with matching front-to-rear fan modules. The rear-to-front equivalent is the PWR-1011-DC-BLUE.

It is listed for the Arista 7280R3 Series, the 7050X3 Series and the 7050 Series 1RU Gen 3, and is also used in 7050X4 switches. Two supplies can be installed for N+1 power redundancy in supported 1RU switches. No licence is required for the power supply itself.

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

FAQs

Q: Does this power supply need a licence?
A: No. The power supply itself does not require a licence or subscription.

Q: What DC input does it need?
A: It accepts -48 to -60 V DC and draws up to 23A at -48V. DC wiring connects through terminal lugs up to AWG #6.

Q: Which Arista switches does it work with?
A: It is listed for the 7280R3 Series, the 7050X3 Series and the 7050 Series 1RU Gen 3, and is also used in 7050X4 switches.

Q: How does this differ from the PWR-1011-DC-BLUE?
A: Both are 1000W DC supplies. The red handle on this unit denotes front-to-rear airflow, while the BLUE version provides rear-to-front airflow.

Q: Which fan modules should it be paired with?
A: Airflow must match across the chassis. Pair this front-to-rear supply with front-to-rear fan modules such as FAN-7011M-F or FAN-7011H-F.
