Cisco PWR-C2-850WAC-IUP | 850W AC Power Supply, 80 PLUS Platinum, Hot-Swappable

Q: Which Cisco switch models are compatible with the PWR-C2-850WAC-IUP?
A: This power supply is designed specifically for Cisco Catalyst 9350 Series Smart Switches. It is a hot-swappable, field-replaceable module that can be installed in any of the three power supply bays supported by C9350 models.

Q: Can I mix different wattage power supplies in a Catalyst 9350 switch?
A: Yes, the Catalyst 9350 Series supports mixing different wattage power supplies (500W, 850W, or 1600W) across the three available bays. The system automatically balances load across active units to improve efficiency and thermal performance while supporting N+1 redundancy configurations.

Q: What are the benefits of 80 PLUS Platinum certification?
A: 80 PLUS Platinum certification indicates 92% energy efficiency, meaning the power supply converts AC input power to DC output with minimal energy loss. This translates to lower electricity costs, reduced heat generation, and decreased cooling requirements in data center and enterprise environments.

Q: Is this power supply hot-swappable?
A: Yes, the PWR-C2-850WAC-IUP is fully hot-swappable and field-replaceable. It can be installed or removed while the switch remains operational, provided at least one other power supply is active, ensuring zero downtime during maintenance or expansion.

Q: How does adding additional power supplies benefit my deployment?
A: Adding a second or third power supply to your Catalyst 9350 switch enables N+1 redundancy for high availability and fault tolerance. Multiple power supplies also increase the total PoE budget available to connected devices and allow automatic load balancing for improved efficiency and thermal management.
