Cisco Catalyst 1900

From Wikipedia, the free encyclopedia

The inside of a Cisco 1900-series switch

The Cisco Catalyst 1900 is a 19" rack mountable, managed (configurable) 10BASE-T Ethernet switch with 100BASE-TX/100BASE-FX uplink ports. This product was popular in small office networks because of its features and price.

This switch was sold until 2002, reaching end of life (EOL) in 2007 and is no longer supported by Cisco.[1]

Models

The switch was available in 12-port and 24-port models with either two 100BASE-TX uplink ports or one fibre and one copper 100 Mbit/s uplink ports. In addition to this, one AUI port was available on the rear panel for connecting to fiber or legacy 10BASE2 or 10BASE5 networks.

This switch is closely related to the Cisco Catalyst 2820 series, which uses the same software, and shares many of the same features
