For the purpose of this manual, whenever a feature applies to all models, the model number will be referenced as
SRW208x. 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 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.

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 (see Figure 3-4). The unit should not be positioned vertically when mounted (see Figure 3-5).

You will need two suitable screws to mount the Switch.

1. Determine where you want to mount the Switch. Ensure that the wall you use is smooth, flat, dry and sturdy
and make sure the location is within reach of the power outlet.

2. Drill two holes into the wall. Make sure the holes are 3.7 inches (94 mm) apart. You can print the template
from this page.

3. Insert a screw into each hole, and leave 3 mm of its head exposed.

4. Maneuver the Switch so the wall-mount slots line up with the two screws.

5. Place the wall-mount slots over the screws and slide the Switch down until the screws fit snugly into the
wall-mount slots.

Congratulations! The Wall-Mount installation of the Switch is complete.

Print this page at 100% size, cut along the dotted
line and place on the wall to drill precise spacing.

Connecting the Switch

To connect network devices to the Switch, follow these instructions:

1. Make sure all the devices you will connect to the Switch are powered off.

2. For 10/100Mbps devices, connect a Category 5 Ethernet network cable to one of the numbered ports on the
Switch. For a 1000Mbps device, connect a Category 5e Ethernet network cable to one of the numbered ports
on the Switch.

3. Connect the other end to a PC or other network device.

4. Repeat steps 2 and 3 to connect additional devices.

5. If you are using the mini-GBIC port, then connect the mini-GBIC module to the mini-GBIC port. For detailed
instructions, refer to the module’s documentation.

6. If you will use the Switch’s console interface to configure the Switch, then connect the supplied serial cable
to the Switch’s Console port, and tighten the captive retaining screws. Connect the other end to your PC’s
serial port. (This PC must be running the VT100 terminal emulation software, such as HyperTerminal.)

7. Connect the supplied power cord to the Switch’s power port, and plug the other end into an electrical outlet.

IMPORTANT: Make sure you use the power cord that is supplied with the Switch. Use of a
different power cord could damage the Switch.

8. Power on the network devices connected to the Switch. Each active port’s corresponding Link/Act LED will
light up on the Switch. If a port has an active Gigabit connection, then its corresponding Gigabit LED will also
light up.

If you will use the Switch’s console interface to configure the Switch, proceed to Chapter 4: Using the

Console Interface for Configuration for directions.

If you will use the Switch’s Web-based Utility to configure the Switch, proceed to Chapter 5: Using the

Web-based Utility for Configuration.
