Linksys EFAH24 EtherFast 10/100 Auto-Sensing 24-Port Hub Rackmount 1U

Linksys EFAH24 EtherFast 10/100 Auto-Sensing 24-Port Hub Rackmount 1U

The Linksys EFAH24 is a 24-port Fast Ethernet hub from the EtherFast product line, designed to provide shared 10/100 Mbps connectivity in a compact 1U rackmount chassis. Each of the 24 RJ-45 ports auto-senses the connected device's speed — 10BASE-T or 100BASE-TX — and adjusts accordingly, eliminating the need for manual speed configuration. Front-panel LED indicators provide per-port link and activity status at a glance.

Applications

Ethernet hubs like the EFAH24 were the standard shared-medium connectivity devices used in small office and workgroup networks during the late 1990s and early 2000s, before managed and unmanaged switches became the dominant choice. In a hub-based network, all ports share a single collision domain, meaning traffic from any port is broadcast to all others — a straightforward topology well-suited to small, low-traffic segments. The EtherFast line was a popular choice for budget-conscious small business and home office deployments connecting PCs, printers, and servers to a common Fast Ethernet segment. Today, units like the EFAH24 are still used in legacy network maintenance, lab bench environments for traffic analysis and protocol testing (where shared-medium behavior is actually desirable), and educational settings demonstrating classic Ethernet operation. The 1U rackmount form factor makes it easy to house in a standard equipment rack alongside other networking gear.
