This guide covers five product models.
•SRW208 - 8-port 10/100 Ethernet Switch with WebView.
Includes 8 10/100 RJ-45 ports.
•SRW208G - 8-port 10/100 Ethernet Switch with WebView and Expansion Slots.
Includes 8 10/100 RJ-45 ports and 1 10/100/1000 RJ-45 port and 1 MiniGBIC slot.
•SRW208L - 8-port 10/100 Ethernet Switch with WebView and 100Base-LX Uplink
Includes 8 10/100 RJ-45 ports and 1 MiniGBIC slot and 1 100LX Uplink port.
•SRW208MP - 8-port 10/100 Ethernet Switch with WebView and Maximum POE (Power over Ethernet)
Includes 8 10/100 RJ-45 ports and 2 10/100/1000 RJ-45 ports and 2 shared MiniGBIC slots.
•SRW208P - 8-port 10/100 Ethernet Switch with WebView and POE (Power over Ethernet)

For the purpose of this manual, whenever a feature applies to allmodels, the model number will be referenced as
SRW208x. If a specific model number is mentioned, then the feature is specific to that model.
TheLinksys WebViewManaged switchallowsyou toexpand yournetwork securely.Configuration ofthe switchis
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.

Chapter 1: Introduction
Welcome
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 Spanning Tree, and Rapid Spanning Tree
(RSTP) allow 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.
The SRW208P and SRW208MP support Automatic Load Sensing - Power control circuitry automatically detects
Power over Ethernet on access point before providing power. Power feeding of Ethernet limited for fixed 10/100
Base-T/TX ports. The SRW208MP can provide maximum output power per PoE port up to 15.4W on 8 ports
simultaneously. while the SRW208P can provide maximum output power on 4 ports simultaneously or 8 ports at
half power.

Overview
The Switches differ in number and types of LEDs and ports. The front panel of each Switch is displayed on one of
the following pages. The back panel is the same on all five models.
SRW208 - Front Panel
The Switch's LEDs and ports are located on the front panel.
LEDs
System Green. The SYSTEM LED lights up to indicate that the Switch is powered on.
Link/Act Green. The LINK/ACT LED lights up to indicate a functional network link through the
corresponding port (1 through 8) with an attached device. It flashes to indicate that the
Switch is actively sending or receiving data over that port.
100M Orange. The 100M LED lights up to indicate a 100Mbps connection on the corresponding
port (1 through 8).

Ports
1-8 The Switch is equipped with 8 auto-sensing, Ethernet network ports, which use RJ-45
connectors. The Fast Ethernet ports support network speeds of 10Mbps or 100Mbps.
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 or 100Mbps),
and adjust its speed and duplex accordingly.
Console The Console port is where you can connect a serial cable to a PC’s serial port for
configuration using your PC’s HyperTerminal program. Refer to Chapter 4: Using the
Console Interface for Configuration for more information.

that the Switch is actively sending or receiving data over that port.
100M Orange. The 100M LED lights up to indicate a 100Mbps connection on the corresponding
port (1 through 8).
Gigabit Orange. The Gigabit LED lights up to indicate a Gigabit connection on the corresponding
RJ-45 port (G1) or miniGBIC port (G2).
