Keep supported Poly voice hardware running with a power supply specified at 5V/3A for US and Canada deployments. This unit is intended for the Edge E100-450 and CCX 350 EM6 environment, giving procurement teams a direct-fit option for maintaining endpoint availability without introducing compatibility risk. For organizations that depend on desk phones and collaboration endpoints, power quality is not a detail — it is part of service continuity. A correctly matched supply helps reduce troubleshooting time, supports predictable replacement planning, and keeps field teams focused on restoring service rather than validating adapters. That matters in distributed offices, contact centers, and front-desk deployments where even brief downtime is visible to users. This model is a practical choice when you need the exact power profile for supported Poly hardware and want to avoid the uncertainty of generic replacements. It is suited to controlled refreshes, spare-parts stocking, and service desk fulfillment where the right part number saves time and reduces operational friction.
