3Com 3C16593B enterprise networking (SuperStack / LinkBuilder / OfficeConnect / CoreBuilder families) Datacentre Switch

The 3Com 3C16593B is a SuperStack 3 Baseline Hub, an unmanaged 10/100Mbps Ethernet hub from 3Com’s entry-level Baseline range within the SuperStack 3 family. As a hub rather than a switch, it shares bandwidth across all connected ports on a single collision domain, making it suited to small workgroups or as a low-cost expansion point rather than a backbone device; SuperStack 3 switch models in the same family (such as the managed 3300 and 4300 series) were used where dedicated per-port bandwidth or management features were needed instead. It was a common low-cost desktop/workgroup connectivity option through the early-to-mid 2000s. 3Com equipment of this generation remains in service across many established SME networks, and a genuine spare such as this restores connectivity after a unit failure. Tech-Star (UK-based, shipped worldwide) stocks 3Com components to support ongoing network maintenance projects.
