Arista PWR-322-DC-RED | DC Power Supply for Arista Switches, Hot-Swappable

Q: What does the red handle indicate on this power supply?
A: The red handle indicates front-to-rear airflow direction, which must match your switch chassis and fan module airflow orientation for proper cooling.

Q: Is this power supply hot-swappable?
A: Yes, the PWR-322-DC-RED supports hot-swap functionality, allowing you to replace the unit without powering down your switch.

Q: Which Arista switches is this power supply compatible with?
A: This power supply is designed for specific Arista modular switch platforms. Please verify compatibility with your exact switch model through Arista documentation or contact technical support.

Q: What is the difference between DC and AC power supplies?
A: DC power supplies connect directly to DC power sources typically found in telco environments, while AC power supplies connect to standard AC mains power. Choose based on your facility's available power infrastructure.

Q: How many power supplies should I install?
A: For redundancy, install at least two power supplies. This provides both component-level and grid-level redundancy, protecting against power supply failure and maintaining operation if one power feed is lost.
