48-Port Gigabit Ethernet Smart Managed Plus Switch
Overview
The switch provides forty-eight 10/100/1000M BASE-T RJ-45 copper ports that support nonstop Layer 2
networks.Two additional ports can accept small form-factor pluggable (SFP) 100M or 1G fiber optical
modules.
You can create high-speed connections using the 1G ports. For example, you can do the following:
• Connect switches to each other with high-speed links (using link aggregation)
• Link to high-speed servers
• Provide 10/100/1000M copper and 100M or 1G fiber connectivity
The switch provides administrative management options that let you configure, monitor, and control the
network. Using the web management interface, you can configure the switch, and the network, including
the ports, the management VLAN, VLANs for traffic control, link aggregation f or increased bandwidth, Quality
of Service (QoS) for prioritizing traffic, and network security.
You can use the web browser-based management interface to enable initial discovery of the switch on the
network and to configure the switch, or you can install the configuration utility on your Windows-based
computer. If you do not use a Windows-based computer, get the IP address of the switch from the DHCP
server in the network or use an IP scanner utility.
The configuration utility runs on Windows-based computers.Visit
Note
netgear.com/support/product/PCU to download the utility to configure your switch.
After discovery , y ou can configure the switch using the web management interf ace or the configuration utility
for basic or advanced setup. For more information, see the user manual which you can download from
downloadcenter.netgear.com.
You can install the switch on a desktop or rack-mount it in a wiring closet or equipment room.The switch is
IEEE compliant and offers low latency for high-speed networking. All ports can automatically negotiate to
the highest speed, which makes the switch very suitable 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 1-Gigibit
connections.
Features
The switch includes the following key hardware features:
• Forty-eight 10M/100M/1G Ethernet ports.
• Two dedicated SFP fiber ports.
• MAC table size of 16K entries.
• 100 Gbps switch fabric full duplex nonblocking.
• System password.
• DHCP client.
• Includes the following mounting hardware:
