24-Port and 48-Port Gigabit Ethernet PoE+ Smart Switches with 4 SFP Ports or 4 10G SFP+ Ports
Overview
The switch provides twenty-four or forty-eight 10/100/1000BASE-T RJ-45 copper ports
that support nonstop 10/100/1000M Layer 2 and Layer 3 networks. All RJ-45 ports
support PoE+. Four additional ports can accept small form-factor pluggable (SFP) gigabit
interface converters (GBICs) for 1G fiber or copper connectivity and, depending on the
model, for 10G fiber or copper connectivity.
You can install the switch freestanding or rack mounted in a wiring closet or equipment
room. The switch is IEEE compliant and offers low latency. All ports can automatically
negotiate to the highest speed, which makes the switch well-suited for a mixed
environment with Fast Ethernet and Gigabit Ethernet.
Use Category 5e (Cat 5e) or higher-rated Ethernet cables terminated with RJ-45
connectors to make Gigabit connections.
You can use the switch for multiple network applications with PoE and PoE+ devices
and non-PoE devices. For more information, see Applications on page 22.
