EMI XZ840919T 17-Port Mini Hub 10Base-T RJ-45 BNC Ethernet Desktop

EMI XZ840919T 17-Port Mini Hub 10Base-T RJ-45 BNC Ethernet Desktop

The EMI XZ840919T is a compact desktop 17-port Ethernet hub designed for 10Base-T (10 Mbps) twisted-pair networks. It provides 16 RJ-45 ports for workstation connections plus a BNC coaxial uplink port for connecting to a 10Base-2 coax segment, making it a useful bridge between twisted-pair and legacy thin-coax network runs.

Applications

10Base-T hubs like the EMI XZ840919T were standard small-office and workgroup networking equipment during the mid-to-late 1990s, when 10 Mbps Ethernet over twisted-pair cabling was the dominant LAN technology. The BNC uplink port allowed the hub to connect into existing thin-coax (10Base-2) backbone runs, which were common in offices transitioning from coax-based bus topologies to star-wired UTP networks. Today these hubs are primarily sought for legacy network maintenance, retro computing setups, vintage computer labs, and thin-client or period-accurate system builds where 10 Mbps half-duplex networking is required.
