Cisco 18W Wall Adapter

This Cisco power adapter delivers 18 watts of output for compatible networking equipment. It is intended for IT professionals and installers who need a direct replacement or spare unit for supported Cisco hardware.

Thermals and Power Draw

The adapter operates at 18 watts under normal load with no active cooling required. Its enclosed wall-mount design runs silently and dissipates heat through the outer casing during continuous use.

18-Watt Output Rating

The single deciding specification is the 18-watt power rating. Devices that require a higher wattage supply will not operate correctly with this unit, so verify the power requirement of your equipment before purchase.

Questions about this item

How do I install the Cisco PWRADPT-WM-18-NA 18W power adapter and what step is often missed?

Plug the adapter into a compatible AC outlet, then connect the output cable to the device. The step often missed is verifying the device requires exactly 18W input before powering on.

What maintenance or replacement will the Cisco PWRADPT-WM-18-NA 18W power adapter need later?

No routine maintenance is required. Replace the unit if the output cable shows fraying, the casing cracks, or the adapter no longer delivers 18W to the connected device.

What limit appears first on the Cisco PWRADPT-WM-18-NA 18W power adapter during sustained use?

The 18W output ceiling is the first limit. Continuous loads at or near 18W will cause the adapter to reach its thermal threshold before any other constraint.
