Enterasys Networks A2H124-24FX - Manual (Page 22)

Overview
1-2 Introduction
Overview
The A2H124‐24FX 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 connections for 10/100/1000 Mbps
• 1000BASE‐SX/LX/ELX fiber‐optic connections for 1‐Gbps fiber‐optic connections
The switch also supports the use of a redundant DC power supply to help prevent
downtime due to an internal power supply failure in the switch or AC power source.
You can install the SecureStack A2 on a flat surface or into a standard 19‐inch rack with
user‐supplied mounting hardware, and configure the SecureStack A2 functions using the
WebView™ application, CLI switching commands, and/or SNMP.
A2H124-24FX
The A2H124‐24FX ( Figure 1‐1 ) has several types of front panel ports and rear panel
connections, which include:
• Twenty Four 100BASE‐FX multimode MT‐RJ Ports
• Two SFP slots labeled port 27 and 28 that support
– optional Mini‐GBIC 1000BASE‐T Ethernet over copper interface connections for
10/100/1000 Mbps operation
– optional 1000BASE‐SX/LX/ELX fiber‐optic connections
• Two 1000BASE‐T RJ45 Ports which can be used in a stack configuration as well as
standard Gigabit Ethernet switch ports when configured as a standalone switch.
• Rear panel Redundant Power Supply connector for a redundant power supply
connection. The switch connects to an Enterasys C2RPS‐SYS using a C2RPS‐PSM
Cable.
Caution: The A2H124-24FX is not a PoE-compliant device. Do not connect a
SecureStack C2 PoE Redundant Power System (C2RPS-POE) to the power connector.
Otherwise, damage to the device may result.
Precaución: El dispositivo A2H124-24FX no cumple con el estándar PoE. No conecte
una fuente de poder redundante (RPS) SecureStack C2 PoE (C2RPS-POE) al cable de
corriente directa. De lo contrario, el dispositivo puede dañarse.
Note: The 1000BASE-T built-in RJ45 stacking ports 25 and 26 on the A2H124-24FX can
be configured as standard 10/100/1000BASE-T switch ports, using the command “set
switch stackport ” when the unit is in standalone mode (not stacked).
