Power adapter Cisco CP-PWR-ADPT-3-EU for 7800 Series IP Phone, EU plug

The Cisco CP-PWR-ADPT-3-EU power adapter is an AC mains adapter designed for Cisco 7800 Series IP Phones. It supplies stable mains power through an EU plug to power compatible desk phones when PoE or inline power is not available. The adapter is compact and intended for straightforward installation, offering an alternative power source for office workstations, home offices, and remote deployment scenarios that require reliable power delivery to Cisco 7800 Series models.

Advantages

The adapter provides a consistent AC power source that eliminates dependence on Power over Ethernet for compatible Cisco 7800 Series phones. Its EU plug form factor fits standard European outlets and the compact design reduces desk clutter. Using a dedicated power adapter can simplify device placement where PoE switches or inline power injectors are not present, and it supports uninterrupted phone operation during network maintenance or configuration changes.

Suitable for

• Powering Cisco 7800 Series IP Phones in offices without PoE-enabled switches
• Home office setups and remote workers using Cisco 7800 desk phones
• Temporary deployments, meeting rooms, or hot-desk stations
• Environments requiring a separate AC power source for telephone endpoints

Key specifications

• Input: AC mains compatible with European (EU) outlets
• Output: DC power matched to Cisco 7800 Series phone requirements
• Connector: Manufacturer-specified plug for direct connection to compatible phone models
• Form factor: Compact wall-mounted adapter with integrated EU plug
• Intended use: External power supply for desktop IP phones when PoE is not available

How to use

Disconnect the IP phone from any existing power source and connect the adapter’s output plug to the phone’s power input port. Insert the EU plug into a standard European mains outlet. Verify the phone powers on and completes its normal boot sequence. If the phone was previously connected to PoE, ensure network cabling remains connected for data while the adapter supplies power. Follow any on-screen or management console prompts to confirm normal operation.

Usage recommendations

Use the adapter only with compatible Cisco 7800 Series IP Phones and in electrical installations that match the adapter’s input rating. Avoid placing the adapter where it may be exposed to liquids or extreme temperatures, and route cables to prevent tripping hazards. For uninterrupted operation in critical environments, consider a UPS on the mains circuit serving the adapter.
