Welcome
Introduction
Introduction
Welcome
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 with
802.1x security using a RADIUS authentication mechanism or MAC-based filtering.
Extensive QoS features make the solution ideal for real-time applications like voice and video.
The four priority queues together with the weighted round robin and strict priority scheduling
techniques facilitate efficient co-existence 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.
Several features allow you to expand and grow your network of switches. Link aggregation
allows multiple high-bandwidth trunks between switches. This feature also provides a level of
reliability so that the system continues to operate if one of the links breaks. Spanning Tree
Protocol (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.

Front Panel
Getting to Know the Switch
Getting to Know the Switch
Front Panel
The switch's LEDs and ports are located on the front panel.
LEDs
System—The System LED lights green to indicate the power is being supplied to the switch.
Lights orange to indicate that the switch’s power-on-self-test (POST) is in progress. Flashes
orange to indicate that the POST has failed.
Link/Act (1-24)—The Link/Act LED lights orange to indicate a functional 1000Mbps network
link through the corresponding port (1 through 24) with an attached device.
Link/Act (1-24)—The Link/Act LED lights green to indicate a functional 10/100Mbps network
link. Flashes to indicate that the switch is actively sending or receiving data over that port.
PoE—The PoE LED lights orange to indicate a powered device is connected to the
corresponding port (1 through 24). Flashes to indicate that the switch is actively sending power
over that port.
Ports
LAN (1-24)—The LAN (Local Area Network) ports connect to Ethernet network devices, such as
other switches or routers.
MiniGBIC (12) /MiniGBIC (24)—The switch is equipped with two mini-GBIC ports. 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 switch. If a Gigabit mini-GBIC port is
being used, the associated LAN port (12 and/or 24) cannot be used. These ports link to a high-
speed network peripheral system or clients at speeds of 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.
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. See Chapter 4: Using the Console Interface
for Configuration for more information.

The Back Panel
Getting to Know the Switch
The Back Panel
The power port is located on the back panel of the switch.
Power—The Power port is where you connect the power cord.
The Side Panel
The security slot is located on a side panel.
Security Slot—The security slot is where you can attach a lock to the switch to help prevent
theft.
LAN Ports
The switch is equipped with 24 auto-sensing RJ-45 LAN ports. These RJ-45 ports support
network speeds of 10Mbps, 100Mbps or 1000Mbps, and 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
mode accordingly.
The switch’s RJ-45 ports also support the IEEE 802.3af Power-over-Ethernet (PoE) standard that
enables DC power to be supplied to attached devices using wires in the connecting twisted-
pair cable. Any 802.3af-compliant device attached to a port can directly draw power from the
switch over the twisted-pair cable without requiring its own separate power source. This
capability gives network administrators centralized power control for devices such as IP phones
and wireless access points, which translates into greater network availability. For each attached
802.3af-compliant device, the switch automatically senses the load and dynamically supplies
the required power. The switch delivers power to a device using the two data wire pairs in the
twisted-pair cable. Each port can provide up to 15.4 W of power at the standard -48 VDC
NOTE: If you need to reset the switch, disconnect the
power cord from the back of the switch. Wait a few
seconds and then reconnect it.

cable.
The Gigabit Expansion Ports
The switch is equipped with two miniGBIC ports that have shared Gigabit Ethernet ports (12
and 24) which provide for the installation of one expansion module. These ports provide links
to high-speed network segments or individual workstations at speeds of up to 1000Mbps
(Gigabit Ethernet). To establish a Gigabit Ethernet connection using a mini-GBIC port, you will
need to install an MGBT1, MGBSX2, or MGBLH1 Gigabit expansion module and use Category 5e
cabling or fiber optic cabling. For more information on fiber optic cabling, see Appendix A,
"About Gigabit Ethernet and Fiber Optic Cabling".
The Console Port
The switch has a console port on the front panel that allows you to connect to a computer’s
serial port (for configuration purposes) using the provided serial cable. You can use
HyperTerminal to manage the switch through the console port. With this and many other
Linksys products, your networking options are limitless. Go to the Linksys website at
www.linksys.com for more information about products that work with the switch.
