Gigabit Ethernet Switches

A Layer 2 switch forwards traffic based on MAC addresses within a single broadcast domain, ideal for access layer switching. A Layer 3 switch adds IP routing capability, letting it route traffic between VLANs and subnets, which is useful for aggregation and core layer deployments requiring inter-VLAN communication.

Yes, when properly refurbished. Each unit undergoes rigorous quality assurance testing, including port diagnostics and burn-in testing, to confirm full functionality. Refurbished switches from Cisco, Juniper, Arista, and Brocade offer the same throughput, port density, and feature sets as new units at a lower cost.

Options range from standard PoE (15.4W per port) to PoE+ (30W per port) and Cisco UPoE (60W per port), supporting IP phones, wireless access points, and security cameras. Higher PoE budgets require larger power supplies, so total switch wattage should be matched to the number and type of powered devices.

Port count depends on device density and growth plans. Common configurations include 24-port and 48-port switches for access layer deployments, while high-density 96+ port chassis switches suit data center core and aggregation layers. Always factor in uplink ports and future expansion when sizing a switch.

Many enterprise-class switches, such as the Brocade ICX6610 series, include dedicated 40G stacking ports that let multiple physical units operate as a single logical switch. This increases port density and simplifies management while maintaining high-speed interconnects between stack members.

Refurbished Gigabit Ethernet switches purchased from Terabit Systems include a 1-year warranty; if a unit fails within that period, it is replaced or fully refunded. All units are backed by an RMA policy and pass a 5-step quality assurance and testing process prior to shipment.
