Pre-owned, used and refurbished Cisco WS-X6548-RJ-21

The WS-X6548-RJ-21 is the 48-port 10/100BASE-T switching module which provides 48 switched, 10/100-Mbps, full- or half-duplex ports. With 4 RJ-21 connectors (12 ports per connector) for Category 5, Category 5e, or Category 6 cables, the WS-X6548-RJ-21 is a highly scalable switching module both new and refurbished. The WS-X6548-RJ-21 module has 1-MB per-port packet buffers and a single fabric channel interface. It is upgradable to support distributed forwarding with an optional Distributed Forwarding Card (WS-F6K-DFC) and is auto-MDI/MDIX capable; customers can use either straight or crossover cable, and the module will automatically detect and adjust for the cable type. It is nothing less than the quality you would expect from Cisco Systems.
