High-speed, Layer 2 Managed
Gigabit Switching
NETGEAR delivers wirespeed Gigabit
performance and a full set of Layer 2
management features with unsurpassed
affordability. These next-generation,
high-speed switches deliver maximum
throughput where you need it ¡X to
high-performance workgroups at the edge
of the network, or as a backbone for
Fast Ethernet switches and high-speed
servers in demanding small networks. The
non-blocking design offers full Gigabit
throughput simultaneously to all 12, 24
or 48 10/100/1000 ports to ensure
reliable performance. Powerful
Full 12, 24 or 48 10/100/1000 ports and
a non-blocking design provide wire speed
throughput and maximum bandwidth for the
most demanding network environments.
Small Form-factor Pluggable (SFP)
modules deliver choice in 1000Base-SX,
1000Base-LX or 1000Base-ZX (70Km)
optics. The Layer 2 management features
optimize bandwidth throughout the
network ¡V delivering Gigabit performance
to systems, applications, and services.
Take advantage of forwarding rates up to
71.4 million pps, and a switching
capacity of 96 Gbps.
Easy to Use
Move up to Gigabit power in minutes. Use
any of these solutions as a managed
switch out of the box ¡V just plug and
play! All ports are auto-negotiating and
support Auto Uplink™ technology. Choose
from two easy-to-use management
interface options ¡VWeb interface or a
command line interface available through
console or Telnet. Comprehensive remote
administration capabilities reduce the
need for on-site administration. Easy to
troubleshoot ¡V built-in testing
capability locates cable related network
problems.
Manageable
Meet your management needs with SNMP
(v1, v2c and v3), RMON, Command-Line
Interface (CLI) and complete Web-based
GUI. Advanced features include up to 512
VLANs, DiffServ traffic prioritization
and 802.1p (QoS) for Voice over IP
services (VoIP), broadcast storm
protection, RADIUS, 802.1x, port
trunking, rapid spanning tree, and link
aggregation. Full Layer 2 implementation
allows you to configure your network for
maximum performance, reliability, and
availability. Manageable with any
popular SNMP-based management software,
but optimized for NETGEAR
ProSafe Network Management Software
NMS100.
Outstanding
Layer 2 management and full Gigabit
power at a compelling price. Use at the
edge to improve workgroup connections,
or at the core to upgrade a Gigabit
Ethernet backbone ¡X now you can afford
the power your network deserves. Like
all NETGEAR products, everything you
need is in the box ¡V including rack
mount kit, power and serial cables, and
more.
