Cisco C9K-ADPT-DC – 80 W DC-DC Adapter

Cisco C9K-ADPT-DC – 80 W DC-DC Adapter

Overview

The Cisco C9K-ADPT-DC is a compact DC-to-DC power adapter designed for use with specific compact models of the Cisco Catalyst 9000 Series, especially those requiring auxiliary power from a DC source. It delivers up to 80 W of power, converting a –48 V DC input (typical in telecom or data-centre environments) to the required DC output for supported switches. Its slim external form enables easy deployment in tight installations such as wall-mount racks or telecom closets. When you need a reliable external adapter rather than internal AC power supplies, the C9K-ADPT-DC provides a straightforward solution to keep compact switches powered and operational.
