Description

The PWR-2411-DC-RED is a hot-swappable 1RU, 73.5 mm power supply module from the Arista 7000 Series range, built for DC-powered data centre and telecom sites. It suits redundant 1+1 power in Arista switches and routers such as the 7060X5 and 7280R3 series, and is recognised by its red handle.

This DC variant takes -48 to -60 VDC input, with a maximum input current of 55 A at -48 V, and delivers 2400 W of output at a typical 94% efficiency. It uses forward (front-to-rear) airflow, so it should be matched to chassis fans and airflow direction. The DC terminal accepts wire up to AWG #6.

It is listed as a supported power supply in the Arista 7060X5 and 7280R3 Series datasheets, and in the 7280R3A Quick Start Guide as a DC supply. AC and DC supply types should not be mixed in the same chassis.

FAQs

Q: What input voltage does this power supply need?
A: It requires a DC feed of -48 to -60 VDC, drawing up to 55 A at -48 V. It does not accept AC input.

Q: Which Arista platforms is it used with?
A: It is listed as a supported power supply for the Arista 7060X5 and 7280R3 Series, and in the 7280R3A Quick Start Guide as a DC supply. The 7060X5 listing calls for a minimum of EOS 4.29.1.

Q: Which airflow direction does the RED variant use?
A: The RED variant uses forward (front-to-rear) airflow. Match it to the airflow direction of the chassis and the other installed supply.

Q: Can I mix AC and DC power supplies in one chassis?
A: No. AC and DC supply types should not be mixed in the same chassis. Use two matching DC supplies for 1+1 redundancy.

Q: What cabling does the DC input accept?
A: The DC terminal accepts wire up to AWG #6. The 7280R3A Quick Start Guide specifies 2-4 AWG (25.0-35.0 mm2) wire with a tightening torque of 2.7 N-m.
