A4H124-24TX P0973JM Enterasys A4 Fast Ethernet Switch

The A4 Fast Ethernet switches are store and forward stackable switches that can be adapted and scaled to help meet your network requirements. These stackable switches provide a management platform 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 to an 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 configure the 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 RJ45 connectors, SFP ports, or Gigabit Ethernet ports, depending on your model’s configuration. The
SFP ports support optional pluggable transceivers, which are hot swappable. The 1000Base‐T built‐in RJ45 stacking ports on the A4 switches can be configured as standard 10/100/1000Base‐T switch ports when the unit is in standalone mode (not stacked).

Stack Connections
The switches have front panel Rj45 ports for connections in a stack configuration. The stackingcables used for the connections must be standard Category 5 or better UTP cable.
Redundant Power Supply capability
The A4 has power supply redundancy capability when connected to an optional externalredundant power supply:
STK-RPS-150PS, a 156 watt DC power supply capable of providing power to a fully-loaded
non-PoE A4 switch.Use with the A4H124-24 and A4H124-48.STK-RPS-500PS, a 500 watt DC power supply for redundant PoE power capability. Use withthe A4H124-24P and A4H124-48PIf the internal power supply fails, the RPS automatically assumes the role of the internal powersupply without interrupting network traffic. The internal power supply and RPS each have theirown AC power connection, which enables the connection of each power supply to a different A(power circuit for additional AC power source redundancy.
Management
Management of the switch can be either in-band or out-of-band. In-band remote management ispossible using Telnet, Enterasys Networks’ NetSight” management application, or the WebViewapplication. Out-of-band management is provided through the DB9 Console port connector on thefront panel using a VT100 terminal or a VT100 terminal emulator.
