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.
The UGREEN 90440 is designed for high-stress environments. For optimal performance in a SKYRS-managed deployment, follow these procedures:
Physical Installation:
Port Identification: Connect the cable to the primary PD (Power Delivery) port of the Cisco endpoint or workstation.
Cable Management: Due to the 240W current capacity, ensure the cable is not tightly coiled to allow for heat dissipation during peak charging cycles.
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.
SKYRS remains the sole provider in Pakistan for the full enterprise-certified variants of the UGREEN 90440.
Variants Available through SKYRS:
UGREEN 90440-2M: The standard 2-meter variant for executive desks and conference tables.
UGREEN 90440-S: Shielded variant for environments with high EMI (Electromagnetic Interference) near server racks.
Service Highlights:
Exclusive Procurement: Available for immediate deployment in Karachi, Lahore, and Islamabad through SKYRS corporate accounts.
Enterprise Warranty: Includes a 12-month SKYRS replacement warranty, ensuring that critical power infrastructure for Cisco endpoints remains operational.
Technical Support: SKYRS provides on-site installation audits to ensure the power source (wall adapters/Cisco units) matches the 240W capability of the cable.
Professional Note: While the 90440 supports extreme power levels, it is a USB 2.0 data cable. For 4K/8K video transmission or 40Gbps data speeds, please consult SKYRS for the Thunderbolt 4 equivalent variants.
