Pre-owned, used and refurbished Cisco WS-C4912G

The Catalyst 4912G, or WS-C4912G, is a feature-rich dedicated Gigabit Ethernet switch designed for customers requiring Layer 2 switching for up to 12 1000- Mbps connections and links that scale to 8 Gbps. Refurbished or new, the WS-C4912G has a nonblocking 24-Gbps architecture enabling all ports to operate simultaneously at wire speed making it cost-effective. All 12 gigabit uplinks support standard GBIC technology enabling you to select and change gigabit interfaces in the Catalyst WS-C4912G easily and inexpensively. With a dedicated configuration of 12 modular Gigabit Ethernet uplink ports, the Catalyst 4912G is fully integrated into the Catalyst family of switches, and uses the same Catalyst system software as the industry-leading Catalyst 5000 family, ensuring complete interoperability with existing Catalyst switches.

The WS-C4912G available is just one of the many options available in the extensive MULTI-LINK (MLCP) switch equipment inventory. Because we maintain a large WS-C4912G inventory, MULTI-LINK can often ship within 1-2 days or even on the same day you order!
