Overview
1-2 Introduction
Overview
The A2H124‐24P and A2H124‐48P are stackable Fast Ethernet switches, which can be
adapted and scaled to help meet your network needs. These switches provide a
management platform and uplink 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 for 1000BASE‐SX/LX/ELX fiber‐optic
connections and 1000BASE‐T copper connections.
The switches also support 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.
A2H124-24P and A2H124-48P
The A2H124‐24P ( Figure 1‐1 ) and A2H124‐48P ( Figure 1‐2 ) have several types of front
panel port connections, which include:
• RJ45 ports (10/100 Mbps, 100BASE‐T copper ports), 24 on the A2H124‐24P and 48 on
the A2H124‐48P.
• SFP slots labeled port 27 and 28 on the A2H124‐24P and 51 and 52 on the A2H124‐48P
that provide you with the option of installing Small Form Pluggable (SFP)
Mini‐GBICs for 1000BASE‐SX/LX/ELX fiber‐optic connections and 1000BASE‐T
copper connections.
• 1000BASE‐T RJ45 stack connectors which can be used in a stack configuration as well
as standard switch ports when configured as a stand alone switch.
• Rear panel Redundant Power Supply connector used to connect to a SecureStack
C2RPS‐POE power supply system using the appropriate cable (C2RPS‐POE cable).
The 10/100 Mbps fixed front panel ports can operate in either half‐duplex or full‐duplex
mode, as determined by Auto‐Negotiation.
Caution: The A2H124-24P and A2H124-48P are PoE-compliant devices. Do not connect
a SecureStack C2 Redundant Power System (C2RPS-SYS) to the power connector.
Otherwise, damage to the device may result.
Precaución: Los dispositivos A2H124-24P y A2H124-48P cumplen con el estándar PoE
(power over ethernet). No conecte una fuente de poder redundante (RPS) SecureStack
C2 (C2RPS-SYS) al cable de corriente. De lo contrario, el dispositivo puede dañarse.
