The Base Switch Models
The AT-8118, AT-8124XL, and AT-8126XL switches are standalone
managed Fast Ethernet switches that provide 16 or 24 10Base-T/
100Base-TX station ports. The AT-8118 and AT-8126XL additionally
provide uplink options of up to two 100Base-TX or 100Base-FX (SC,
MT-RJ or VF-45) ports for backbone connectivity
They are primarily intended for connections to the desktop as well as
workgroup applications. The AT-8118 and AT-8126XL, when
populated with optional uplink ports, implement direct high-speed
server and backbone connections. Half- or full-duplex capability on
all ports eliminate collisions and provide up to 200 Mbps of
bandwidth per port to servers, routers, and other switches. The auto-
negotiating ports allow connectivity between devices operating at
10 Mbps and 100 Mbps speeds.
With built-in management, the switches provide seamless
management capability such as SNMP and web-based management.
