Cisco WS-C1924-EN enterprise networking (router/Catalyst switch/UCS families) Datacentre Switch

The Cisco WS-C1924-EN is a Catalyst 1900 Series fixed-configuration Ethernet switch, Enterprise Edition, with 24 dedicated 10BaseT ports plus two 100BaseTX Fast Ethernet uplink ports. The Catalyst 1900 family was Cisco’s entry-level stackable workgroup switch line, built for wiring-closet deployments needing dedicated 10 Mbps to desktops with a fast Ethernet path back to the backbone or server farm. The Enterprise Edition firmware on the -EN variant adds ISL VLAN trunking, CGMP multicast pruning and fuller SNMP/RMON management over the cut-down Standard Edition image, making it suitable for switched-VLAN environments rather than a flat single-segment network. Catalyst 1900 hardware still turns up in legacy campus networks, training labs and equipment being kept running until a wider refresh, where a spare unit restores port capacity or replaces a failed switch without forcing an unplanned upgrade. This is a refurbished unit; confirm your existing 1900 stack’s firmware level and uplink media before ordering, and Tech-Star (UK-based, shipped worldwide) can advise on compatible transceivers and stacking cables.
