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 for Web 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.
