Overview

The A2H254‐16 is a stackable Fast Ethernet switch, which can be adapted and scaled to help meet your network needs. This switch provides a management platform and uplinks to a network backbone for a stacked group of up to eight A2 switches. The two built‐in Small Form Pluggable (SFP) interface slots provide you with the option of installing Mini‐GBICs. The various versions of hot swappable Mini‐GBICs provide you with the flexibility to install interfaces that support:

1000BASE‐T Ethernet over copper for 1‐Gbps RJ45 connections

1000BASE‐SX/LX/ELX fiber‐optic connections for 1‐Gbps fiber‐optic connections
