In a multi-location retail chain, the WS-X4516-Catalyst 4500 10/100 Auto Module (48-Ports RJ-45) delivers 48 fast-Ethernet ports at the network edge to connect POS terminals, Wi-Fi access points and staff workstations. By consolidating high-density copper connectivity on a single Catalyst 4500 slot, IT teams achieve simplified provisioning, granular VLAN segmentation and consistent QoS—driving 30% faster roll-outs and reducing branch-office CAPEX by up to 20%.
University IT leverages the WS-X4516 module in a Catalyst 4500 to aggregate 48 lab PCs and VoIP phones per building floor, enforcing role-based VLANs for students, faculty and voice traffic. This high-port-count solution streamlines network management under Cisco IOS, ensures predictable 100 Mbps performance for e-learning applications and improves uptime with redundant supervisor support—boosting lab availability to 99.99%.
In a manufacturing plant, engineers deploy the WS-X4516-Catalyst 4500 module to connect 48 sensors, PLCs and barcode scanners with dedicated VLANs for production, safety and analytics traffic. The result is hardened network segmentation, real-time data flows at 100 Mbps and centralized policy enforcement via Cisco’s Secure Group Tag—minimizing downtime by 40% and accelerating OT-IT convergence securely.
