Cisco PWR-ADPT
AC-DC power adapter for the C9200CX-12T-2X2G compact switch (80W)
Product Highlights
Deploying a Cisco Catalyst C9200CX-12T-2X2G compact switch in a location where upstream 802.3bt PoE power isn't available? The Cisco PWR-ADPT is the purpose-built solution — an 80-watt AC-DC power adapter that provides a reliable auxiliary power path for the C9200CX-12T-2X2G.
The C9200CX-12T-2X2G is unique among the Catalyst 9200CX compact switches in that it does not include an internal power supply. Instead, it can be powered via an 802.3bt Class 6 PoE uplink or through an external auxiliary adapter like the PWR-ADPT. This adapter accepts a universal AC input of 100–240V at 50/60 Hz and converts it to 54V DC output, delivering up to 80 watts to the switch.
Whether used as the primary power source or as a backup alongside PoE, the PWR-ADPT ensures uninterrupted switch operation. Its slim, compact design fits naturally into the space-constrained environments — retail branches, hospitality venues, classrooms, and industrial edge locations — where the C9200CX is typically deployed. For installations using a mounting tray or DIN rail, Cisco offers the optional C9K-ADPT-BRKT-12T bracket to secure the adapter in place.
The Cisco PWR-ADPT is a genuine Cisco accessory that gives network teams the flexibility to power the C9200CX-12T-2X2G from any standard AC outlet, eliminating dependency on upstream PoE infrastructure.
Features & Benefits
Flexible Power Delivery
The PWR-ADPT provides an alternate AC power path for the C9200CX-12T-2X2G, which can otherwise only be powered via 802.3bt Class 6 PoE. This flexibility lets you deploy the switch in locations where PoE infrastructure doesn't exist or isn't practical, expanding your site options without re-engineering the upstream network.
Universal AC Input
With a 100–240V AC input range at 50/60 Hz, the PWR-ADPT works with standard power outlets worldwide. There's no need for external voltage converters or region-specific adapters, simplifying procurement and inventory for multi-site or international deployments.
Primary or Backup Power Role
The adapter can serve as the sole power source or operate alongside a PoE uplink for added resilience. When both auxiliary power and PoE are connected, the auxiliary adapter takes precedence; if auxiliary power is removed, the switch seamlessly transitions to PoE after re-detection. This dual-source capability supports high-availability edge deployments.
Compact, Space-Saving Design
The slim form factor of the PWR-ADPT complements the compact C9200CX chassis, making it ideal for under-desk, wall-mount, or DIN-rail installations. For tray or DIN-rail mounted switches, the optional C9K-ADPT-BRKT-12T bracket secures the adapter neatly alongside the switch.
Deployment Scenarios
Retail Branch or Small Office Without PoE Infrastructure
In retail stores, small offices, or pop-up locations where there is no upstream PoE switch, the PWR-ADPT lets you power the C9200CX-12T-2X2G directly from a standard wall outlet. This eliminates the need to deploy additional PoE-capable upstream equipment just to power the compact switch.
Hospitality and Classroom Edge Deployments
Hotels, conference rooms, and classrooms often require discreet, fanless switches in tight spaces. The PWR-ADPT provides a clean AC power option for the C9200CX-12T-2X2G in these environments, avoiding the complexity of running PoE from a distant wiring closet.
Redundant Power for High-Availability Edge Sites
For mission-critical edge locations such as healthcare clinics or financial kiosks, connecting both the PWR-ADPT and a PoE uplink to the C9200CX-12T-2X2G provides dual power paths. The auxiliary adapter takes priority, and the switch can fall back to PoE if the AC source is interrupted, improving overall uptime.
