WS-X6148A-RJ-45 Use Case
Enterprise VoIP and Wireless Access PoE Deployment
In a large corporate campus, the WS-X6148A-RJ-45-Catalyst 6500 48-Port 10/100 w/TDR, Upgradable - PoE 802.3af powers 48 IP phones and wireless access points over a single chassis slot. Integrated Time-Domain Reflectometry (TDR) accelerates cable fault isolation, while PoE 802.3af ensures reliable device boot‐up and centralized power management. Benefit: reduces rack space and electrical circuit complexity by 50%, maximizes uptime for voice and Wi-Fi services.
Scalable Data Center Aggregation with Future-Proof Upgradability
In a mid-tier data center, network engineers install the WS-X6148A-RJ-45 module as a Gigabit uplink aggregation layer, later upgrading ports from 10/100 to 1G with a software key. PoE 802.3af supports edge security cameras and environmental sensors without additional injectors. Benefit: delivers a 2× throughput increase and streamlines power cabling, cutting capital outlay by 30% and extending chassis lifecycle.
Distributed Campus Cable Diagnostics and Monitoring
A university IT department deploys multiple Catalyst 6500 chassis populated with WS-X6148A-RJ-45 cards in geographically dispersed buildings. Automated TDR diagnostics pinpoint cable shorts and opens across 48 ports without manual tracing. PoE 802.3af powers intercom endpoints and door controllers. Benefit: lowers mean time to repair (MTTR) by 60% and ensures continuous operation of critical safety and communication systems.
