Description
The A4 Fast Ethernet switches are store and forward stackable switches that can be adapted andscaled to help meet your network requirements. These stackable switches provide a managementplatform and an uplink to a network backbone for a stacked group of up to eight A4 switches.You can also use a redundant power supply with these switches to help prevent downtime due toan internal power supply failure in the switch or AC power source.You can install the stackable switch on a flat surface or into a standard 19-inch rack, and configurethe stackable switch functions using the WebView™ application, CLI switching commands, and/or SNMP.The A4 stackable switch can connect to Ethernet networks or workstations through RJ45connectors, SFP ports, or Gigabit Ethernet ports, depending on your model’s configuration. TheSFP ports support optional pluggable transceivers, which are hot swappable. The 1000Base-Tbuilt-in RJ45 stacking ports on the A4 switches can be configured as standard 10/100/1000Base-Tswitch ports when the unit is in standalone mode (not stacked).For pluggable transceiver compatibility and specifications, refer to the datasheet athttp://www.enterasys.com/products/transceivers-ds.pdf.Table 1-1Table 1-1 A4 Switch Port TypesA4 ModelA4H124-24FX(seeFigure 1-1lists the number of ports and port types for the A4 switches.on page 1-2)Ports• 24 100Base-FX MT-RJ ports• Two 10/100/1000Base-T RJ45 ports which can be usedas stacking ports or as Ethernet uplink ports (labeled 25and 26)• Two Gigabit Ethernet SFP ports (labeled 27 and 28)
