Maintain reliable power for supported Poly CCX endpoints with the CCX 500/505/600/700 Edge E500 Power Supply with Power Cord. This accessory is specified for environments that need a direct power source for compatible desk phones, especially where PoE infrastructure is unavailable, inconsistent, or intentionally separated from the voice network. With a 48 V, 0.52 A output, it provides the electrical profile required for the Edge E500 configuration. The included power cord simplifies deployment and helps standardize installations across offices, call centers, and distributed workspaces. For procurement teams, it is a practical way to complete a phone rollout without depending on network switch power budgets. This is a targeted accessory, not a generic adapter. It is intended to support the CCX family in real-world enterprise voice environments where uptime, desk consistency, and predictable accessory compatibility matter. When a deployment needs a direct power path, this supply keeps the endpoint ready for calls, collaboration, and daily operations.
