Welcome

Thank you for choosing the Cisco 200 Series 8-Port Smart Switch, a Cisco

Small Business network communications device. This device is designed

to be operational right out-of-the-box as a standard bridge. In the default

configuration, it will forward packets between connecting devices after

powered up.

Package Contents

•Cisco SG200-08 or SG200-08P Smart Switch.

•Power Adapter.

•This Quick Start Guide.

•Product CD.

This guide will familiarize you with the layout of the smart switch and

describe how to deploy the device in your network. For additional

information, see www.cisco.com/smb.

Mounting the Cisco Switch

There are two ways to mount the switch:

• Set the switch on a flat surface.

•Mount the switch on a wall

Do not deploy the device in a location where any of the following

conditions exist:

High Ambient Temperature—The ambient temperature must not

exceed 104 degrees Fahrenheit (40 degrees Centigrade).

Reduced Air Flow—Both side panels must be unobstructed to prevent

overheating.

Mechanical Overloading—The device should be level, stable, and

secure to prevent it from sliding or shifting out-of-position.

Circuit Overloading—Adding the device to the power outlet must not

overload that circuit.

Wall Mounting

NOTE The switch should be mounted so that the ports face up or down.

Do not mount the switch with the ports to the side, as this causes strain

on the connections.

There is a wall-mount kit packed with your switch. The dimensions for the

mount kit are as follows:

Mount the smart switch to the wall by drilling two pilot holes 95 mm (3.7

inches) apart, attaching the provided anchors and screws to the wall, then

sliding the switch into position on the screws.

The switch must have a minimum of 5 inches (130 mm) of clearance on all

sides.

WARNING Insecure mounting might damage the device or cause injury.

Cisco is not responsible for damages incurred by insecure wall-

mounting.

Connecting Network Devices

To connect the smart switch to the network:

STEP 1Connect the Ethernet cable to the Ethernet port of a computer,

printer, network storage, or other network device.

STEP 2Connect the other end of the Ethernet cable to one of the

numbered smart switch Ethernet ports.

The LED of the port lights if the device connected is active. Refer to

Features of the Cisco Small Business Smart Switch, page 8 for

details about the different ports and LEDs on each switch.

STEP 3Repeat Step 1 and Step 2 for each device you want to connect to

the smart switch.

NOTE Cisco recommends using Cat5 or better cable for Gigabit

connectivity. When you connect your network devices, do not exceed

the maximum cabling distance of 328 feet (100 meters). It can take up to

one minute for attached devices or the LAN to be operational after they

are connected. This is normal behavior.

Power over Ethernet Considerations

If your switch is one of the Power over Ethernet (PoE) models, consider the

following power requirement:

•As a Power Sourcing Equipment (PSE) device, the switch can deliver a

maximum of 15.4 Watts per PoE port to a Powered Device (PD).

•The total power budget available for all devices is 32 Watts.

•Ports 1-4 are PoE ports, 5-8 are standard Ethernet ports.

WARNING The switch should be connected only to PoE networks without

routing to the outside plant

Configuring the Cisco Small Business

Smart Switch

Before You Begin

Verify that a computer with Microsoft Internet Explorer (version 6 or higher)

or Firefox (version 2.0 or higher) is available.

Accessing and Managing Your Switch Using the Web-

Based Interface

In order to access the switch with a web-based interface, you must know

the Management IP address of the switch. The default configuration of the

switch is to use its factory default IP address of 192.168.1.254 until it has

obtained an IP address from a DHCP server, or it has been changed to a

static IP address.

When the switch is using the factory default IP address, its System LED

flashes continuously. When the switch is using a DHCP assigned IP

address or an administrator configured static IP address, the system LED

lights steady.

NOTE If the smart switch IP address is changed, either by a DHCP server

or manually, your access to the smart switch will be lost and you must

use the new IP address to configure the switch.

Use the Web-Based Interface

To configure the smart switch:

STEP 1Power on the computer and the switch.

STEP 2Connect the computer to the switch. You can connect to the same

IP subnet as the switch by connecting them directly with an

Ethernet cable, or by connecting to the same LAN where the

switch is located through other switches. You can also connect

your computer to the switch from another IP subnet through one or

more IP routers.

STEP 3Set up the IP configuration on your computer.

a. If the switch is using the default static IP address of

192.168.1.254, you must choose an IP address in the range of

192.168.1.2—192.168.1.253 that is not already being used by

another device.

b. If the IP addresses will be assigned by DHCP, make sure your

DHCP server is running and can be reached from the switch

and the computer. You might need to disconnect and

6 200 Series 8-Port Smart Switches

reconnect the devices for them to discover their new IP

addresses from the DHCP server.

NOTE Details on how to change the IP address on your computer

depend upon the type of architecture and operating system you are

using. See your computer’s local Help and Support functionality

and search for “IP Addressing.”

STEP 4Open a Web browser window. If you are prompted to install an

Active-X plug-in when connecting to the device, follow the

prompts to accept the plug-in.

STEP 5Enter the switch IP address in the address bar and press Enter. For

example, http://192.168.1.254.

The Smart Switch Login page

displays.

STEP 6Enter the login information:

Username is cisco

Default password is cisco (passwords are case sensitive)

STEP 7If this is the first time that you have logged on with the default

username and password, the

Change Password

page opens. Enter

a new administrator password and then click Apply.

CAUTION Make sure that any configuration changes that you made are

saved before exiting from the web-based interface by

clicking on the Save icon, then clicking Apply. Exiting before

you save your configuration will result in all changes being

lost.

The Getting Started window displays. You are now ready to configure the

switch. Refer to the

Cisco Small Business Smart Switch Administration

Guide

for further information.

Next Steps

•If you are not using DHCP on your network, set the connection

type on the smart switch to Static and change the static IP

address and subnet mask to match your network topology.

•Save your settings.

•Return your computer to its original settings.

These tasks can be accomplished by using the procedures in the Cisco

Small Business Smart Switch Administration Guide.

Troubleshoot Your Connection

If you cannot access your switch from the web-based interface, the switch

may not be reachable from your computer. You can test network

connections by using the ping command. The following example shows

how to use "ping" in a Windows environment:

STEP 1Open a command window by using Start > Run and enter cmd.

STEP 2At the Command window prompt enter ping and the smart switch

IP address. For example ping 192.168.1.254 (the default IP address

of the smart switch).

If you can reach the switch, you should get a reply similar to the

following:

Pinging 192.168.1.254 with 32 bytes of data:

Reply from 192.168.1.254: bytes=32 time<1ms TTL=128

If you cannot reach the switch, you should get a reply similar to the

following:

Pinging 192.168.1.254 with 32 bytes of data:

Request timed out.

Possible Causes and Resolutions

No Power:

Power up the switch and your computer if they are turned off.

Bad Ethernet connection:

Check the LEDs for proper indications. Check the connectors of the

Ethernet cable to ensure they are firmly plugged into the switch and

your computer.

Wrong or conflicting IP address:

Make sure that you are using the correct IP address of the switch. You

can verify the correct IP address of the switch with your network

administrator. The System LED provides an indication of where the

switch received the IP address, see Section 4 for details.

Make sure that no other device is using the same IP address as the

switch.

No IP route:

If the switch and your computer are in different IP subnets, you need

one or more routers to route the packets between the two subnets.

8 200 Series 8-Port Smart Switches

•Unusually long access time:

Due to the spanning tree loop detection logic, adding new connections

might take 30 to 60 seconds for the affected interfaces and/or LAN to

become operational.

Features of the Cisco Small Business

Smart Switch

This section describes the exterior of the smart switches including ports,

LEDs, and connections.

Back Panel Ports

The Ethernet ports are located on the back panel of the switch.

RJ-45 Ethernet Ports—Use these ports to connect network devices, such

as computers, printers, and access points, to the switch. If your switch

supports PoE, ports 1-4 can provide PoE and ports 5-8 are standard

Ethernet ports.

Front Panel LEDs

The LEDs are located on the front of the switch.

System LED—(Green) Lights steady when the switch is powered on, and

flashes when booting, performing self tests, and acquiring an IP address. If

the LED flashes amber, the switch has detected a hardware failure.

LINK/ACT LED—(Green) Lights steady when a link between the

corresponding port and another device is detected. Flashes when the port

is passing traffic.

Side Panel

Power—The Power port is where you will connect the switch to power.

Returning the Device to the Factory

Default Settings

The 8-Port Smart Switch models does not have a Reset button. To return

the device to factory default settings, follow the instructions in the Cisco

Small Business Smart Switch Administration Guide.
