Gigabit Switch with
WebView
Model: SRW248G4
Secure, reliable, intelligent,
high density, managed switching
for your growing business
Growing businesses require cost effective, networking solutions that can scale with
ever changing business needs.The Linksys SRW248G4 Switch with WebView brings
a whole new level of intelligence and security to the network infrastructure.The 48
10/100 Mbps ports enable you to consolidate your network from several smaller
switches/hubs to a single, managed switch.The optional gigabit optical interfaces allow
you to expand the network as your business grows.
Network security is a top priority in any size business. Most business data networks, large
and small, are unsecure. Unauthorized access to the network and mission critical data
is a constant concern.The SRW248G4 is able to secure the network through 802.1X port
authentication and MAC-based filtering. 802.1X requires clients to authenticate themselves
before the port will pass data.
Businesses are recognizing the benefits of doing Voice over IP (VoIP) and are quickly
migrating their voice services to IP based platforms, requiring their local area networks to
support both voice and data applications. In unmanaged IP networks, bursty data sessions
can disrupt voice packet delivery, causing poor voice quality.With the enhanced QoS and
traffic management features in the SRW248G4, voice data can be prioritized, ensuring clear and
reliable voice communications.
Enabling the SRW248G4 advanced features further secures the integrity of your network.The
WebView interface provides an intuitive, secure management interface enabling you to better
utilize the comprehensive feature-set of the switch, resulting in a better optimized, more secure
network.
Simplified,web based user
management for more
intelligent networking
Quad gigabit uplinks for
increased bandwidth and
redundancy
802.1X port authentication
and MAC address filtering
brings network security
down to the switch port

QoS enables the network
to be optimized for your
networked applications,
including voice, video and
data storage
