Nortel Baystack 250 Model 253 ... price-per-port value. All BayStack 250 Series 10/100 Autosense Hubs support 10/100 autosensing on all ports, enabling seamless migration from 10 Mbps to 100 Mbps connections. Equally important, they do so without requiring time-consuming trips to the wiring closet whenever end stations are upgraded to Fast Ethernet. A built-in two-port switch in the BayStack 250, 253, 254, and 255 Hubs provides high-speed connectivity between 10 Mbps users and 100 Mbps users. The built-in two-port switch allows for greater performance through segmentation. This eliminates the need for an external switch to communicate between 10 Mbps users and 100 Mbps users.

Versatile and flexible, BayStack 250 Series 10/100 Autosense Hubs satisfy a range of needs: from small, unmanaged LANs to large, feature-rich managed networks. As demands grow, users can stack up to five hubs. The stack will function as a single managed unit, providing a scalable solution that enables networks to grow incrementally for a very affordable investment.
