Description

This Arista PWR-511-DC-BLUE is a hot-swappable 500W DC power supply module for the Arista 7050X3 Series of 1RU fixed data centre switches. The blue handle denotes rear-to-front (reverse) airflow, making it suited to hot and cold aisle layouts where the switch ports face the cold aisle. It suits a spare or redundant supply in telco and DC-powered data centre sites.

The module accepts a -48 to -60 VDC input, delivers 500W of output power and has a typical efficiency of 92%. Maximum input current is 11.8A at -48V, and connection is via terminal lugs for AWG #14 maximum DC wire. It fits in a slim 73.5mm 1RU form factor. With two PSU slots per switch, one supply can carry the load of the host switch while the second provides 1+1 redundancy.

It is listed for 7050CX3-32S, 7050CX3-32C, 7050SX3-48C8, 7050SX3-48C8C and 7050TX3-48C8, as well as other 7050X3 1RU models. The supply airflow must match the fan tray airflow in the switch, so do not mix airflow directions. It is a different unit from the PWR-500-DC-F/R and PWR-1011-DC-RED/BLUE supplies.

FAQs

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

Q: Which Arista switches does it fit?
A: It is used in the Arista 7050X3 Series 1RU switches, including the 7050CX3-32S, 7050CX3-32C, 7050SX3-48C8, 7050SX3-48C8C and 7050TX3-48C8. Minimum EOS release varies by model.

Q: What input power does it need?
A: It requires a -48 to -60 VDC input with a maximum input current of 11.8A at -48V, connected through terminal lugs for AWG #14 maximum wire.

Q: Can I mix it with front-to-rear airflow supplies or fan trays?
A: No. Airflow directions should not be mixed. The blue handle means rear-to-front airflow, which must match the fan tray airflow in the switch.

Q: Is it the same as the PWR-500-DC or PWR-1011-DC supplies?
A: No. PWR-511-DC-BLUE is a different unit from the PWR-500-DC-F/R and PWR-1011-DC-RED/BLUE supplies, so choose it specifically for 7050X3 switches that use it.
