Description

The PWR-D2-3041-DC-BLUE is a 3000W DC dual-input, 1RU hot-swappable power supply for the Arista 7800R3 Series of modular data centre switch routers. It suits redundant DC power in spine, core, peering, internet edge and backbone deployments, particularly carrier and data centre sites that run on -48VDC power plants.

The module accepts two independent DC feeds, each rated -48 to -60VDC at up to 70A, connected through two M6 lug-type studs. It delivers 3000W of output at 94% efficiency and includes an internal variable speed fan. Each power supply integrates 1+1 power redundancy, giving grid-level redundancy across two separate power feeds. It measures 6.8 x 4.1 x 60.0 cm and weighs 3.6 kg.

It installs in the DCS-7804, DCS-7808, DCS-7812, DCS-7816 and DCS-7816L chassis. Chassis power slot counts determine the total budget: 8 slots (24 kW) on the 7804, 12 slots (36 kW) on the 7808, 18 slots (54 kW) on the 7812, and 24 slots (72 kW) on the 7816 and 7816L. This is the DC dual-input variant, distinct from the AC options in the 7800R3 family.

FAQs

Q: Which chassis does the PWR-D2-3041-DC-BLUE fit?
A: It is supported in the Arista 7800R3 Series chassis: DCS-7804, DCS-7808, DCS-7812, DCS-7816 and DCS-7816L.

Q: What DC input does it require?
A: It has two independent DC inputs, each accepting -48 to -60VDC at up to 70A maximum, connected via two M6 lug-type studs.

Q: How many power supplies can a 7800R3 chassis take?
A: The 7804 has 8 power slots (24 kW maximum budget), the 7808 has 12 (36 kW), the 7812 has 18 (54 kW), and the 7816 and 7816L have 24 (72 kW).

Q: Is this an AC or DC power supply, and how does it differ from the siblings?
A: This is the DC dual-input model. The AC siblings in the family are PWR-D1-3041-AC-BLUE and PWR-D4-3041-AC-BLUE, which suit AC and high-voltage feeds instead of -48 to -60VDC.

Q: Does it support power redundancy?
A: Yes. Each power supply integrates 1+1 power redundancy, and the dual DC inputs allow connection to two independent feeds for grid redundancy.
