Introduction
Thank you for choosing Linksys WebView Switches. This
User Guide covers five product models:
SRW2048•48-port 10/100/1000 Gigabit Switch with
WebView. Includes 48 10/100/1000 RJ-45 ports and 4
shared SFP (MiniGBIC) slots.
SRW2024•24-Port 10/100/1000 Gigabit Switch with
WebView. Includes 24 10/100/1000 RJ-45 ports and 2
shared SFP (MiniGBIC) slots.
SRW2016•16-Port 10/100/1000 Gigabit Switch with
WebView. Includes 16 10/100/1000 RJ-45 ports and 2
shared SFP (MiniGBIC) slots.
SRW248G4•48-port 10/100 + 4-Port Gigabit Switch
with WebView. Includes 48 10/100 RJ-45 ports and 4
10/100/1000 RJ-45 ports and 2 shared SFP (MiniGBIC)
slots.
SRW224G4•24-port 10/100 + 4-Port Gigabit Switch
with WebView Includes 24 10/100 RJ-45 ports and 4
10/100/1000 RJ-45 ports and 2 shared SFP (MiniGBIC)
slots.
For the purpose of this manual, whenever a feature
applies to all models, the name WebView Switch will be
referenced. If a specific model number is mentioned, then
the feature is specific to that model.
The Linksys WebView Managed Switch allows you to
expand your network securely. Configuration of the switch
is secured using SSL forWeb access. User control is secured
using 802.1x security using a RADIUS authentication
mechanism and can also be controlled using MAC-based
filtering.
Extensive QoS features makes the solution ideal for real-
time applications like Voice and Video. The 4 priority
queues together with the Weighted Round Robin and
Strict Priority scheduling techniques facilitate efficient
coexistence of real-time traffic with data traffic allowing
them each to meet their QoS needs.
Individual users or applications can be prioritized above
others using various Class of Service options - by port,
layer 2 priority (802.1p), and Layer 3 priority (TOS or
DSCP). Intelligent Broadcast, and Multicast storm control
minimizes and contain the effect of these types of traffic on
regular traffic. IGMP Snooping limits bandwidth-intensive
video traffic to only the requestors without flooding to all
users.
Incoming traffic can be policed and outgoing traffic can
be shaped allowing you to control network access and
traffic flow.
There are features that allow you to expand and grow your
network of switches. Link aggregation allows multiple
high-bandwidth trunks between switches to be setup.
This also provides a level of reliability in that the system
continues to operate if one of the links break. Spanning
Tree (STP), Fast Linkover, Rapid Spanning Tree (RSTP) and
Multiple Spanning Tree (MSTP) allows you to build a mesh
of switches increasing the availability of the system.
The rich management functionality of the WebView
switches includes SNMP, RMON, Telnet, and HTTP
Management options, allowing you to flexibly integrate
and manage these devices in your network.

SRW2048
Front Panel
The Switch’s LEDs and ports are located on the front
panel.
Front Panel of the SRW2048
LEDs
POWER (Green) Lights up green to indicate
that power is being supplied to the Switch.
LINK/ACT (1-48) (Green/Amber) Lights up
green to indicate a functional 10/100-Mbps
network link through the corresponding port (1
through 48) with an attached device. It flashes
to indicate that the Switch is actively sending
or receiving data over that port. Lights up
amber to indicate a 1000-Mbps connection on
the corresponding port (1 through 48) with an
attached device. It flashes to indicate that the
Switch is actively sending or receiving data over
that port.
ETHERNET 1-48 The Switch is equipped with
48 auto-sensing, Ethernet network ports, which
use RJ-45 connectors. The Fast Ethernet ports
support network speeds of 10 Mbps, 100 Mbps,
or 1000 Mbps. They can operate in half and
full-duplex modes. Auto-sensing technology
enables each port to automatically detect the
speed of the device connected to it (10 Mbps,
100 Mbps, or 1000 Mbps), and adjust its speed
and duplex accordingly.
MiniGBIC (1-4) The miniGBIC (gigabit interface
converter) port is a connection point for a
miniGBIC expansion module, so the Switch can
be uplinked via fiber to another switch. The
MiniGBIC port provides a link to a high-speed
network segment or individual workstation at
speeds of up to 1000 Mbps.
Use the Linksys MGBT1, MGBSX1, or MGBLH1
miniGBIC modules with the Switch. The
MGBSX1 and the MGBLH1 require fiber cabling
with LC connectors, while the MGBT1 requires
a Category 5e Ethernet cable with an RJ-45
connector.
NOTE: On the SRW2048, MiniGBIC ports are
shared with standard ports. If a miniGBIC port
is used, then the shared standard port on the
Switch cannot be used. The following table
provides port mapping details of the SRW2048
Switch.

CONSOLE The Switch is equipped with a
serial port labeled Console (located on the
back of the switch) that allows you to connect
to a computer’s serial port (for configuration
purposes) using the provided serial cable. You
can use HyperTerminal to manage the Switch
using the console port.
Refer to Chapter 4: Configuration Using the
Console Interface for more information.
NOTE: If you need to reset the Switch, unplug
the power cord from the back of the Switch.
Wait a few seconds and then reconnect it.
