Applications
Ungermann-Bass hubs were used in legacy Ethernet networks of the 1990s for workgroup connectivity and network segmentation. The STM24 was deployed in corporate and institutional environments where distributed hub architecture was standard before switched networking became prevalent. The three-segment design allowed traffic isolation and network expansion within structured cabling systems.
This Ungermann-Bass STM24 Access/Stax 24-Port Ethernet Hub has been inspected and is in good used condition. The chassis is clean overall with minor cosmetic wear typical of rack-pulled equipment. All 24 RJ-45 ports appear intact, the front-panel LEDs, serial port, and media expansion port are present and undamaged, and the rear expansion ports show no obvious physical damage.
