Chapter 1: Introduction

Welcome

This 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.

WebView Switches

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.

Ports

1-24 The Switch is equipped with 24 auto-sensing, Ethernet network ports, which use RJ-45

connectors. The Fast Ethernet ports support network speeds of 10Mbps, 100Mbps, or
1000Mbps. 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 (10Mbps,
100Mbps, or 1000Mbps), and adjust its speed and duplex accordingly.

G1-G4 The Switch is equipped with 4 auto-sensing Gigabit Ethernet network ports, which use RJ-

45 connectors. The Gigabit Ethernet ports support network speeds of 10Mbps, 100Mbps,
or 1000Mbps. 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 (10Mbps,
100Mbps, or 1000Mbps), and adjust its speed and duplex accordingly.

miniGBIC 1-2 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 switc h. The MiniGBIC
port provides a link to a high-speed network segment or individual workstation at speeds
of up to 1000Mbps.

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.

Placement Options

Before connecting cables to the Switch, first you will physically install the Switch. Either set the Switch on its four
rubber feet for desktop placement or mount the Switch in a standard-sized, 19-inch wide, 1U high rack for rack­mount placement.

Desktop Placement

1. Attach the rubber feet to the recessed areas on the bottom of the Switch.

2. Place the Switch on a desktop near an AC power source.

3. Keep enough ventilation space for the Switch and check the environmental restrictions mentioned in the
specifications.

4. Proceed to the section, “Connecting the Switch.”

Rack-Mount Placement

To mount the Switch in any standard-sized, 19-inch wide, 1U high rack, follow these instructions:

1. Place the Switch on a hard flat surface with the front panel facing you.

2. Attach a rack–mount bracket to one side of the Switch with the supplied screws. Then attach the other
bracket to the other side.

IMPORTANT: Make sure you use the screws
supplied with the mounting brackets. Using the
wrong screws could damage the Switch and would
invalidate your warranty.
