Item Description

Dell PowerConnect 7048R 48-PORT 10/100/1000MBps Gigabit Managed Ethernet Network Switch J7MFN 0J7MFN CN-0J7MFN. Help meet your network switching needs, no matter how large your organization, with the Dell Networking 7048R. It features 48 ports of wire-speed L3 GbE plus robust security and enterprise management capabilities. The 7048R offers two optional flexible airflow configurations to align with front-to-back and back-to-front server installations. A USB configuration also aids in rapid deployment. Optional dedicated 64GB stacking interfaces and 10GB uplinks help you grow your switch with your network, enabling you to add 10GB without even rebooting your switch. Stack up to 12 switches (managed as a single unit) for high-performance availability and failover deployments, including those with Dell Networking M6348 high-density 48-port I/O modules for the PowerEdge™ M1000E blade enclosure.
