In a multi-building enterprise campus, the WS-X4748-UPOE+E in a Catalyst 4503 Supervisor II-Plus chassis aggregates 48 PoE+ 10/100/1000 access switches and eight fiber uplinks over SFP. This deployment delivers consistent 1 Gbps throughput, dynamic QoS for voice/video, and 1200 W total PoE budget, reducing rack-space and simplifying management. Outcome: predictable performance and unified power delivery for Wi-Fi 6, IP telephony and digital signage across hundreds of endpoints.
A global finance firm leverages the Catalyst 4503 Supervisor II-Plus with WS-X4748-UPOE+E to power 48 IP phones and eight SFP uplinks at each branch. Centralized PoE management and hardware-based call prioritization deliver sub-5 ms latency and secure MPLS transport for voice traffic. Outcome: streamlined provisioning, 30% lower cabling costs, and carrier-grade voice availability across 200+ locations.
In a cloud service provider environment, the Catalyst 4503 with WS-X4748-UPOE+E operates as a top-of-rack switch, aggregating server NICs via 1 GbE PoE+ and linking to spine switches via eight 10 Gbps SFP+. Hardware-based traffic shaping and supervisor-level redundancy support live VM migrations and tenant isolation. Outcome: 40% higher port density, seamless failover, and optimized power distribution for converged compute/storage workloads.
