Overview of the C9K-80W-ADPT=

The ​​C9K-80W-ADPT=​​ is a ​​compact 80W AC power adapter​​ designed for Cisco’s Catalyst 9200 and 9300 Series switches, as detailed on Cisco.com. This adapter provides a cost-effective, space-saving power solution for edge deployments where high-density Power over Ethernet (PoE) isn’t required, such as small offices, retail branches, or IoT gateway setups.

Core Technical Specifications

• ​​Power Output​​: 80W total (60W for PoE+, 20W for system operations), supporting non-PoE and ​​light PoE​​ devices like IP phones or basic access points.
• ​​Input Flexibility​​: Accepts 100–240V AC, enabling global deployment without voltage converters.
• ​​Compact Design​​: 30% smaller than standard Catalyst power supplies, ideal for cramped network closets.
• ​​Compatibility​​: Certified for Catalyst 9200L, 9200, and 9300 switches (non-stackable models).

Addressing Key User Concerns

​​Q: Can the C9K-80W-ADPT= support PoE+ cameras or APs?​​
Yes, but only ​​up to 4–6 devices​​ depending on power draw. For high-density PoE+, use the ​​C9K-715W-AC​​ instead.

​​Q: Is it hot-swappable?​​
No. The adapter requires the switch to be powered off before installation or removal.

​​Q: Does it work with Catalyst 9400 or 9500 chassis?​​
No. Cisco.com confirms compatibility is ​​limited to 9200/9300 Series fixed switches​​.

Use Cases Highlighted by Cisco.com

• ​​Retail Checkout Systems​​: Powers POS terminals and VoIP phones without overprovisioning.
• ​​Remote Offices​​: Lightweight power for switches handling VPN traffic and basic IoT sensors.
• ​​Classroom Deployments​​: Supports small clusters of Wi-Fi-enabled tablets or interactive displays.

Purchasing and Cost Considerations

• ​​Refurbished Availability​​: itmall.sale often stocks recertified adapters at 40–50% lower cost.
• ​​Bundles​​: Pair with Catalyst 9200L switches for plug-and-play edge networking kits.

Final Perspective

Having deployed Catalyst 9200s in rural clinics and kiosks, the C9K-80W-ADPT= solves the “overkill power” dilemma. While it can’t replace high-wattage PSUs, its ability to quietly power low-demand setups without hogging space or budget is invaluable. In regions with unstable grids, pairing it with a UPS ensures reliable uptime for critical but lightweight operations. For lean IT teams, this adapter is a silent workhorse—unassuming but indispensable.
