Description

The Arista PWR-3K-DC-RED is a 3000 W DC-input power supply module for Arista 7500N Series modular switch chassis. It accepts -48 or -60 V DC nominal input through front-panel terminals and uses a red ejector handle for fitting and removal, making it suited to data centres and telecommunications sites running DC power plants.

This hot-swappable module is supported in the DCS-7504N, DCS-7508N, DCS-7512N and DCS-7516N chassis, with up to 4, 8, 12 and 20 power supplies respectively. It supports N+1 and redundant power configurations. When replacing a failed unit, use the same PSU model and avoid mixing PSU types within a chassis.

Features

- Hot-swappable modular power supply with ejector handle
- Supports N+1 or redundant power configurations in 7500N chassis
- Front-panel status LED for at-a-glance power status
- Dedicated -48V, RTN and ground terminals for DC cabling
