Introduction

Chapter 1: 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.

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.

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.

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 realtime 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.

Before You Install the Switch...

When you choose a location for the Switch, observe the following guidelines:

Make sure the Switch is accessible and that the cables • can be easily connected.

Keep cabling away from sources of electrical noise, • power lines, and fluorescent lighting fixtures.

Position the Switch away from water and moisture • sources.

To ensure adequate air flow around the Switch, provide • a minimum clearance of two inches (50 mm).

Uplink via Fiber

to Switch

Placement Options

There are two ways to physically install the Switch, either set the Switch on its four rubber feet for desktop placement or mount the switch in a standard-sized, 482.6-mm wide, 1U-high rack for rack-mount placement.

Desktop Placement

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

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

Keep enough ventilation space for the switch and • check the environmental restrictions mentioned in the Specifications Appendix as you are placing the Switch.

Connect the Switch to network devices according to • the Hardware Installation instructions below.

Rack-Mount Placement

When rack-mounting the Switch, please observe the following guidelines

Elevated Operating Ambient • If installed in a closed

or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the room ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

Reduced Air Flow • Installation of the equipment

in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

Mechanical Loading • Mounting of the equipment in

the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

Circuit Overloading • Consideration should be given

to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable Earthing • Reliable earthing of rack-mounted

equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (for example, use of power strips).

Do not stack free-standing Switches more than four • units high.
