Installation Procedure:
Physical Mounting: Plug the UGREEN 55321 into a standard Type-G (3-pin) wall socket or vertical PDU. Its slim profile ensures it does not obstruct adjacent power ports.
Device Link: Connect a high-quality USB-C to USB-C (or Lightning) cable to the charger.
Endpoint Integration: Connect the other end to the Cisco Wireless IP Phone or mobile terminal.
Environment Check: Ensure the unit is placed in a ventilated area; the internal thermal management system will handle heat dissipation during rapid 25W charging cycles.
The 55321 is a “Smart” charging unit that requires no manual software configuration. It utilizes an internal chipset to communicate with the Cisco device’s power management controller.
PPS (Programmable Power Supply): For Cisco-compatible Android terminals, the PPS protocol allows for micro-adjustments in voltage and current, reducing heat generation during the charging process.
Handshake Verification: Upon connection, the unit performs a digital handshake to determine the optimal charging profile (PD 3.0 or PPS), ensuring the safety of the connected device’s battery.
Vertical Stability: The reinforced pins and vertical balance of the casing ensure a steady connection in high-traffic areas like IT helpdesks or staging rooms.
SKYRS is the sole verified distributor for the UGREEN 55321 and its specialized variants within the Pakistan market, providing enterprise-grade supply chain reliability.
Available Variants at SKYRS:
UGREEN 55321 Standard: The 25W PD standalone unit (UK/Pakistan Plug).
