Introduction
8-Port 10/100/1000 Gigabit Switch with Webview
Chapter 1
Chapter 1:
Introduction
Welcome
This guide covers three product models.
SRW2008•8-port 10/100/1000 Ethernet Switch with
WebView. Includes 8 10/100/1000 RJ-45 ports and 2
shared MiniGBIC slots.
SRW2008MP•8-port 10/100/1000 Ethernet Switch
with WebView and Maximum POE (Power over
Ethernet) Includes 8 10/100/1000 RJ-45 ports and 2
shared MiniGBIC slots.
SRW2008P•8-port 10/100/1000 Ethernet Switch with
WebView and POE (Power over Ethernet) Includes 8
10/100/1000 RJ-45 ports and 2 shared MiniGBIC slots.
For the purpose of this manual, whenever a feature applies
to all models, the model number will be referenced as
SRW2008x. 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 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 SRW2008P and SRW2008MP 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

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.
Gigabit (Orange) The Gigabit LED lights
up to indicate a Gigabit 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, 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.
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.
miniGBIC1/2 The mini-GBIC (gigabit interface
converter) port is a connection point for a
mini-GBIC expansion module, so the Switch
can be uplinked via fiber to another switch.
Each 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
mini-GBIC 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.

Typical Network Configuration
When you connect your network devices, make sure you
don’t exceed the maximum cabling distance of 100 meters
(328 feet).
Positioning the Switch
Before you choose a location for the Switch, observe the
following guidelines:
Make sure that the Switch is accessible and that the•
cables can be connected easily.
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, be•
sure to provide a minimum clearance of two inches
(50mm).
Do not stack free-standing Switches more than four•
units high.
Placement Options
There are three ways to physically install the Switch,
either set the Switch on its four rubber feet for desktop
placement, mount the switch in a standard-sized, 19-inch
1U high rack for rack-mount placement, or horizontally on
the wall.
Desktop Placement

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 room ambient. 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 (e.g. use of
power strips).
To rack-mount the Switch in any standard 19-inch rack,
follow the instructions described below.
Place the Switch on a hard flat surface with the front1.
panel facing you.
Attach a rack–mount bracket to one side of the Switch2.
with the supplied screws.Then attach the other bracket
to the other side.
WARNING: Make sure you use the screws
supplied with the mounting brackets. Using the
wrong screws could damage the Switch and
would invalidate your warranty.
Attaching the Brackets
Make sure the brackets are properly attached to the3.

Wall-Mount Placement
When mounting the Switch on the wall, the Switch should
be mounted horizontally. The front panel should face
either up or down. The unit should not be positioned
vertically when mounted. You will need two suitable
screws to mount the Switch. Use the template above to
plan your installation.
