Running a data center with DC power distribution?

The Cisco C9K-PWR-930WDC-R delivers 930 watts of DC power for your Catalyst 9500 switch. Built for telecom facilities, data centers, and industrial environments where DC power is standard. Replace a failed unit or add backup power fast.

What you get:

10-year warranty. If this power supply fails in the next 10 years, we replace it. No questions. No delays.

930 watts of DC capacity. Handles moderate to heavy PoE loads plus full switch operation. Power 30 to 40 IP phones, 15 to 20 access points, or a mix of cameras and sensors.

Fully tested and certified. Every unit runs through load testing at full capacity. We verify DC input stability, output regulation, and thermal performance before shipping.

Hot-swappable installation. Slide it into the power bay. Lock the handle. Your network stays up. No shutdown required.

Why you need DC power:

Most data centers run DC distribution.

Telecom facilities and large data centers use -48VDC power. It is more efficient than AC for high-density environments. Plus you can run backup batteries without conversion losses.

Redundancy protects critical infrastructure.

Install two power supplies in your C9500. If one fails, the second keeps everything running. No dropped connections. No emergency calls. Just uninterrupted service.

More power means more devices.

The 930W supply handles enough PoE load for:

• 35 to 40 IP phones
• 15 to 18 wireless access points
• 10 to 12 PTZ security cameras
• Or any combination up to the power budget

Think of it like a backup generator in a hospital. You hope you never need it, but when power fails, lives depend on it working.
