2 Cisco 200 Series Smart Switches

Welcome

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

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.

Before you begin installing the switch, make sure you have all of the

package contents available, access to the

Cisco 200 Series Smart Switch

Administration Guide

, and a PC with a web browser for using web-based

system management tools.

Package Contents

•Cisco 200 Series Smart Switch

•Rackmount Kit

•Power Cord or 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/go/200switches.

Mounting the Cisco Switch

There are two ways to mount the switch:

• Set the switch on a flat surface.

• Mount the switch in a standard rack (1 rack unit high).

Do not mount 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).

NOTE Some switches have a higher temperature rating. The SG200-

10FP, SF200-24FP, SG200-26FP, and SG200-50FP are rated at 113

degrees Fahrenheit (45 degrees Centigrade).

•ReducedAirFlow—Both side panels must be unobstructed to prevent

overheating.

• Mechanical Overloading—The device must be level, stable, and

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

Cisco 200 Series Smart Switches 3

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

overload that circuit.

Rack-Mount Placement

STEP 1Remove the four screws from each side near the front of the switch.

Retain the screws for re-installation. (Do not remove the four screws

from each side near the back of the switch.)

STEP 2Place one of the supplied spacers on the side of the switch so the

four holes of the spacers align to the screw holes. Place a rack

mount bracket next to the spacer and reinstall the four screws

removed in Step 1.

NOTE If your screws are not long enough to reattach the bracket

with the spacer in place, attach the bracket directly to the case

without the spacer.

STEP 3Repeat Step 2 for the other side of the switch.

STEP 4After the mounting hardware has been securely attached, the

switch is now ready to be installed into a standard 19-inch rack.

CAUTION For stability, load the rack from the bottom to the top, with the

heaviest devices on the bottom. A top-heavy rack is likely to

be unstable and might tip over.

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 200 Series Smart Switches 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 strongly recommends using Cat5 or better cable for Gigabit

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

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

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

connected. This is normal behavior.

Power over Ethernet Considerations

WARNING The switch is to be connected only to PoE networks without

routing to the outside plant.

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

following power requirement:

CAUTION Consider the following when connecting switches capable of

supplying PoE:

The PoE models of the switches are PSE (Power Sourcing

Equipment) that are capable of supplying DC power to

attaching PD (Powered Devices). These devices include VoIP

phones, IP cameras, and wireless access points. The PoE

switches can detect and supply power to pre-standard

legacy PoE Powered Devices. Due to the support of legacy

PoE, it is possible that a PoE switch acting as a PSE may

mistakenly detect and supply power to an attaching PSE,

including other PoE switches, as a legacy PD.

Even though PoE switches are PSE, and as such should be

by another PSE due to false detection. When this happens,

the PoE switch may not operate properly and may not be

able to properly supply power to its attaching PDs.

6 Cisco 200 Series Smart Switches

To prevent false detection, you should disable PoE on the

ports on the PoE switches that are used to connect to PSEs.

You should also first power up a PSE device before

connecting it to a PoE switch. When a device is being falsely

detected as a PD, you should disconnect the device from the

PoE port and power recycle the device with AC power

before reconnecting its PoE ports.

Configuring the Cisco 200 Series Smart

Switches

Before You Begin

Verify the managing computer requirements in the product release notes.

Accessing and Managing Your Switch Using the Web-

Based Interface

To access the switch by using the web-based interface, you must know

the IP address the switch is using. The switch uses the factory default IP

address of 192.168.1.254 by default.

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

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

address or an administrator has configured a static IP address, the System

LED is on solid (DHCP is enabled by default).

NOTE If you are managing the switch through a network connection and

the switch IP address is changed, either by a DHCP server or manually,

your access to the switch will be lost. You must enter the new IP address

the switch is using into your browser to use the web-based interface.

To configure the smart switch:

STEP 1Power on the computer and the switch.

STEP 2Set the IP configuration on your computer.

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

192.168.1.254, you must chose an IP address for the computer

in the range of 192.168.1.1—192.168.1.253 that is not already in

use.

b. If the IP addresses is assigned by a DHCP server, make sure

the DHCP server is running and can be reached from the

switch and the computer. It might be necessary to disconnect

Cisco 200 Series Smart Switches 7

and 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. Use the computer Help and Support functionality to search

for “IP Addressing.”

STEP 3Open 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 4Enter the switch IP address in the address bar and press Enter. For

example, http://192.168.1.254.

The Switch Login Page

displays.

STEP 5Enter the default login information:

•Username is cisco

•Default password is cisco (passwords are case sensitive)

STEP 6If this is the first time that you have logged on with the default

username and password, the

Change Password Page

opens. The

rules for constructing a new login and password are displayed on

the page. Enter a new administrator password and click Apply.

CAUTION Make sure that any configuration changes made are saved to

the Startup configuration before exiting from the web-based

interface by clicking on the Save icon. Exiting before you

save your configuration will result in all current changes

being lost the next time the switch is rebooted.

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

switch. Refer to the

Cisco 200 Series Smart Switch Administration Guide

for further information.

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 ping on a computer running Windows:

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 current 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.

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 200 Series Smart

Switches

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

LEDs, and connections. Not all models will have all of the features

described.

Ports

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

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

SFP (if present)—The small form-factor pluggable (SFP) ports are

connection points for modules, so the switch can link to other switches.

These ports are also commonly referred to as miniGigaBit Interface

Converter (miniGBIC) ports. The term SFP will be used in this guide.

•SFP ports are compatible with Cisco modules MGBT1, MGBSX1,

MGBLH1, MGBLX1, MGBBX1, MFELX1, MFEFX1, and MFEBX1, as well as

other brands of modules.

• Some SFP interfaces are shared with one other RJ-45 port, called a

combo port. When the SFP is active, the adjacent RJ-45 port is

disabled.

•The LEDs of the corresponding RJ-45 port flashes green to respond to

the miniGBIC interface traffic.

LEDs

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) Located on the left of the port. Lights steady

when a link between the corresponding port and another device is

detected. Flashes when the port is passing traffic.

NOTE The System and LINK/ACT LEDs are on each model of the switch.

The following LEDs are only present on switch models that have those

capabilities:

10 Cisco 200 Series Smart Switches

PoE (if present)—(Amber) Located on the right of the port. Lights steady to

indicate that power is being supplied to a device attached to the

corresponding port.

100M LED (if present)—(Green) Located on the right of the port. Lights

steady when another device is connected to the port, is powered on, and a

100 Mbps link is established between the devices. When the LED is off, the

connection speed is under 100 Mbps or nothing is cabled to the port.

Gigabit LED (if present)—(Green) Located on the right of the port. Lights

steady when another device is connected to the port, is powered on, and a

1000 Mbps link is established between the devices. When the LED is off,

the connection speed is under 1000 Mbps or nothing is cabled to the port.

SFP (if present)—(Green) Located on the right of a GE port. Lights steady

when a connection is made through the shared port. Flashes when the port

is passing traffic.

Additional Features

The switch might also have a reset button. The switch can be reset by

inserting a pin or paper clip into the reset opening. See Returning the

Device to the Factory Default Settings for details.

Back Panel

The power port is located on the back panel of the smart switch.

Returning the Device to the Factory

Default Settings

To use the Reset button to reboot or reset the smart switch, do the

following:

• To reboot the smart switch, press the Reset button for less than 10

seconds.

•To restore the smart switch configuration to the factory default settings:

1. Disconnect the smart switch from the network or disable all DHCP

servers on your network.

2. With the power on, press and hold the Reset button for more than

10 seconds.
