Deployment in Cisco and Enterprise Ecosystems

The 90440 series is a vital component for organizations deploying Cisco Catalyst SD-WAN components or Cisco Webex Desk series endpoints where high-wattage power stability is mandatory.

Deployment Roles:

  • Conference Room Integration: Powering Cisco Webex Desk Mini and Desk Pro units that require stable, high-current delivery over USB-C.

  • Unified Workspace: Standardizing the power interface for various hardware fleets, including high-performance engineering laptops that exceed the 100W limit.

  • Network Reliability: Utilizing the E-Marker chip to prevent hardware damage from voltage spikes in high-density office deployments.


Installation and Configuration

The UGREEN 90440 is designed for high-stress environments. For optimal performance in a SKYRS-managed deployment, follow these procedures:

Physical Installation:

  1. Port Identification: Connect the cable to the primary PD (Power Delivery) port of the Cisco endpoint or workstation.

  2. Cable Management: Due to the 240W current capacity, ensure the cable is not tightly coiled to allow for heat dissipation during peak charging cycles.

  3. Endpoint Connection: Ensure the receiving device supports PD 3.1 to achieve the full 240W potential; otherwise, the E-Marker chip will automatically handshake at 60W or 100W for safety.

System Configuration:

  • Cisco Webex Tuning: No firmware adjustment is needed for the cable, but administrators should verify that the USB-C settings in the Cisco Control Hub are set to “Power Delivery Enabled.”

  • Smart Monitoring: On supported laptops, the built-in E-Marker chip communicates directly with the OS to provide real-time battery health and charging status data.
