What Is the CP-6901-C-K9= and How Does It Streamline Cisco VoIP Deployments? Functionality, Regional Use, and Sourcing Options

Overview of the CP-6901-C-K9=

The ​​CP-6901-C-K9=​​ is a Cisco regional power adapter specifically engineered for the ​​6900 Series IP Phones​​, optimized for use in the United Kingdom and Ireland. This component provides compliant power delivery aligned with UK/Irish electrical standards (230V AC, 50Hz), ensuring seamless integration into Cisco Unified Communications environments.

Core Technical Features

• ​​Compatibility​​: Tailored for Cisco 6901 IP Phones, supporting ​​PoE (Power over Ethernet)​​ or direct power via its 3-pin UK plug.
• ​​Output​​: Delivers ​​48V DC​​ with built-in surge protection, critical for maintaining uptime in environments prone to voltage fluctuations.
• ​​Certifications​​: Meets BS 1363 safety standards, ensuring compliance for corporate or public-sector deployments.

Addressing User Concerns

​​Q: Can the CP-6901-C-K9= be used in non-UK regions?​​
A: No. It is designed exclusively for ​​UK/Irish voltage standards​​. Attempting to use it in 110V regions like North America risks device failure or safety hazards.

​​Q: Is this adapter compatible with newer Cisco desk phones?​​
A: While physically similar, newer IP Phone models (e.g., 7800/8800 Series) often require updated power specifications. Always verify compatibility with Cisco’s documentation.

Procurement and Legacy Support

Cisco.com no longer lists the CP-6901-C-K9= in active portfolios, but it remains accessible through platforms like “itmall.sale”, which focuses on ​​refurbished Cisco collaboration hardware​​. This is particularly valuable for organizations maintaining legacy VoIP systems while balancing budget constraints.

Personal Perspective

In managing Cisco VoIP upgrades across multinational offices, I’ve noticed that mismatched power adapters like the CP-6901-C-K9= are a frequent failure point in “cost-cutting” setups. For UK-based teams, investing in region-specific, certified components avoids the hidden costs of downtime or non-compliance. While newer Power over Ethernet (PoE) switches reduce dependency on physical adapters, the CP-6901-C-K9= remains indispensable for hybrid deployments—provided it’s sourced from trustworthy suppliers like itmall.sale to avoid counterfeit risks.
