Maintain voice availability without reworking the network. The Yealink YLPOE30 POE Injector adds standards-based power delivery to a single Ethernet drop, making it a practical fit for conference rooms, executive desks, and retrofit deployments where PoE switching is limited or already fully allocated. Built for Yealink endpoints, it supports IEEE 802.3af and IEEE 802.3at and passes data at 10/100/1000M speeds. That gives IT teams a clean way to power compatible Yealink IP phones and the CP960 conference phone while preserving gigabit connectivity. The 54 V, 0.56 A output aligns with common PoE device requirements, and the 100-240 V AC input supports straightforward deployment across standard office power environments. For organizations that value uptime and controlled rollout costs, a dedicated injector can be the right answer when replacing switches is unnecessary. It keeps the install simple, reduces dependency on spare PoE ports, and helps extend the life of existing network infrastructure.
