Cisco PWR-2504-AC
Cisco 2504 Wireless Controller Spare Power Supply
Product Highlights
When your wireless network is the backbone of daily operations, a failed power supply can bring everything to a halt. The Cisco PWR-2504-AC is the genuine spare AC power adapter engineered specifically for the Cisco 2504 Wireless Controller (CT2504), giving you a drop-in replacement that restores service quickly or a hot-spare that prevents downtime altogether.
This external power adapter accepts a wide AC 100–240V input at 50/60 Hz, making it suitable for deployments anywhere in the world without voltage conversion concerns. It is designed to work seamlessly with the full range of Cisco 2500 Series Wireless Controllers, including the AIR-CT2504-5-K9, AIR-CT2504-15-K9, AIR-CT2504-25-K9, AIR-CT2504-50-K9, and AIR-CT2504-HA-K9 models.
Whether you are maintaining a branch-office wireless deployment, supporting a retail environment, or managing a campus network still running the proven CT2504 platform, stocking a spare PWR-2504-AC ensures your wireless infrastructure stays online. Its compact, external design means replacement requires no chassis disassembly — simply swap the adapter and resume operations.
Features & Benefits
Universal AC Input
The PWR-2504-AC accepts AC 100–240V at 50/60 Hz, eliminating the need for step-down transformers or region-specific power supplies. Deploy or relocate your Cisco 2504 controller globally with a single power adapter SKU.
Genuine Cisco Replacement
As the factory-original spare part, the PWR-2504-AC is built to Cisco's exact electrical and safety specifications. Using a genuine adapter protects your controller hardware and preserves any active Cisco service contracts.
Quick Swap, Minimal Downtime
The external adapter design means no tools and no chassis access are required for replacement. Keep a spare on the shelf and swap in seconds to restore wireless controller operations with minimal disruption to connected access points and clients.
Low Thermal Footprint
With a heat dissipation of just 72 BTU/hour, the PWR-2504-AC keeps thermal output low — an important consideration in space-constrained wiring closets and IDF rooms where cooling capacity may be limited.
Deployment Scenarios
Branch Office Spare Inventory
Organizations with multiple branch offices running Cisco 2504 controllers can stock PWR-2504-AC units at regional depots. A failed power supply can be replaced on-site within minutes, avoiding the cost and delay of emergency procurement or overnight shipping.
Retail & Hospitality Environments
Retail stores and hotels relying on the CT2504 for guest Wi-Fi and point-of-sale connectivity need maximum uptime. A pre-positioned spare power adapter ensures that a single component failure does not take the entire wireless network offline during peak business hours.
Education & Small Campus Networks
Schools and small campuses using the Cisco 2500 Series to manage classroom and common-area access points benefit from having a replacement power supply readily available, keeping students and staff connected without waiting for next-day service.
