Description

This hot-swappable 500W AC power supply, the 500v2 revision, is built for the Arista 7050X3 Series. It is the rear-to-front airflow version for the 7050CX3-32S-D data centre switch, and suits leaf or spine switches where a spare or replacement supply is needed to keep the 1RU chassis running.

The unit delivers 500W of output from a 100-240V AC input at 50/60Hz, with a typical input current of 6.3 to 2.3A. Typical efficiency is 93%, which is 80 PLUS Platinum class, and power connects through a standard IEC 60320 C14 inlet. The host switch has two power supply slots that run in a 1+1 redundant, hot-swap arrangement. This SKU is the 500v2, rear-to-front variant, and the front-to-rear equivalent is a separate part, so airflow direction should match the rest of the installation.

It is intended for the DCS-7050CX3-32S-D switch with rear-to-front airflow. It is not the same part as the older PWR-500AC-R used in the 7050X, 7280 and 7060CX 1RU switches.

FAQs

Q: Which switch does this power supply fit?
A: It is for the Arista 7050CX3-32S-D data centre switch in the rear-to-front airflow configuration, such as the DCS-7050CX3-32S-D-R.

Q: Can I mix airflow directions in the same switch?
A: No. Both power supplies and the switch fans should use the same airflow direction. The front-to-rear equivalent of this unit is PWR-501AC-F.

Q: Does the power supply need a licence?
A: No licence is required for the power supply itself. Any EOS feature licence requirements apply to the host 7050X3 switch, not this module.

Q: What power input does it need?
A: It accepts 100-240V AC at 50/60Hz through an IEC 60320 C14 inlet, with a typical input current of 6.3 to 2.3A.

Q: Is this the same as the PWR-500AC-R?
A: No. The PWR-500AC-R is an older, non-v2 part for the 7050X, 7280 and 7060CX 1RU switches. This 500v2 unit is for the 7050CX3-32S-D.
