WS-X4748-RJ45V+E Use Case
Data Center Cooling Redundancy with WS-X4748-RJ45V+E Spare Fan Tray
In a high-density data center running a Cisco Catalyst 4507R-E chassis, deploying the WS-X4748-RJ45V+E spare fan tray ensures N+1 cooling redundancy. By hot-swapping the spare fan tray during peak CPU and traffic loads, IT teams maintain optimal inlet temperatures, prevent thermal shutdowns, and uphold 99.999% uptime SLAs.
Branch Office Network Resilience Using WS-X4748-RJ45V+E Fan Tray Replacement
A geographically dispersed branch office relying on a Catalyst 4507R-E switch keeps a WS-X4748-RJ45V+E fan tray on-site for rapid replacement. This reduces mean time to repair (MTTR) from hours to minutes, eliminating extended outages, protecting VoIP call quality, and safeguarding local application performance.
Hot-Swap Maintenance in Enterprise Core with WS-X4748-RJ45V+E Spare Fan Tray
During scheduled maintenance on the enterprise core Catalyst 4507R-E chassis, network operators insert the WS-X4748-RJ45V+E spare fan tray without powering down the system. This zero-impact swap prevents service disruptions, extends chassis lifespan by maintaining optimal airflow, and aligns with change-control best practices for high-availability networks.
