This guide will familiarize you with the layout of the managed switch and
describe how to deploy the device in your network. For additional information,
see www.cisco.com/smb.
1 Mounting the Cisco Switch
There are three ways to physically install the switch:
· Set the switch on a flat surface.
· Mount the switch on a wall (8-port devices only).
· Mount the switch in a standard rack (1 rack unit high).
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.
2
300 Series Managed Switches
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.
Rack-Mount Placement
To rack-mount the switch in any standard rack, attach the rackmount brackets
to the sides of the switch with the supplied hardware and secure the brackets
tightly.
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 may tip over.
Wall Mounting
Only the 8-port models of the switch can be wall-mounted. 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. There is a wall-mount kit packed with your switch.
The dimensions for the mount kit are as follows:

2 4
196243
1 8 mm/0.4 in 2 22.2 mm/0.9 in 3 6.8 mm/0.3 in 4 17.6 mm/0.7 in
Mount the managed switch to the wall by drilling two pilot holes 3.7 inches
(95 mm) apart, attaching the provided anchors and screws to the wall, then
sliding the switch into position on the screws.
The switch should have a minimum of 5 inches (130 mm) of clearance on all
sides.

WARNING Insecure mounting may damage the device or cause injury. Cisco is not
responsible for damages incurred by insecure wallmounting.
2 Connecting Network Devices
To connect the managed switch to the network:
STEP 1 Connect the Ethernet cable to the Ethernet port of a computer, printer,
network storage, or other network device.
STEP 2 Connect the other end of the network Ethernet cable to one of the
numbered managed switch Ethernet ports. The LED of the port lights if the
device connected is active. Refer to Features of the Cisco Small Business
Managed Switch, page 10 for details about the different ports and LEDs on each
switch.
STEP 3 Repeat Step 1 and Step 2 for each device you want to connect to the
managed 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 (PoE) Considerations
If your switch is one of the PoE models, consider the following: As a PSE
(Power Sourcing Equipment) device, the switch can deliver a maximum of 15.4
Watts per PoE port to a PD (Powered Device).

3 Configuring the Cisco Small Business Managed Switch
Before You Begin
Verify that a computer with Microsoft Internet Explorer (version 6 and higher)
or Firefox (version 2.0 or higher) is available.
The switch can be accessed and managed by two different methods; over your IP
network using the web-based interface, or by the menu CLI through the console
port. Using the console port requires advanced user skills.
Accessing and Managing Your Switch Using the WebBased Interface
In order to access the switch with a web-based interface, you will need to
know the IP address the switch is using. 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.
When the switch is using the factory default IP address, its power LED flashes
continuously. When the switch is using a DHCP assigned IP address or an
administrator configured static IP address, the power LED is on solid.
NOTE If the managed switch IP address is changed, either by a DHCP server or
manually, your access to the managed switch will be lost and you must enter
the new IP address to use the web-based interface.
Use the Web-Based Interface
To configure the managed switch:
STEP 1 Power on the computer and the switch.
STEP 2 Connect 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 3 Set 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 chose an IP address in the range of 192.168.1.2-192.168.1.253 that is not
already in use.
b. If the IP addresses will be assigned by DHCP, make sure your DHCP server is
running and can be reached from the switch
300 Series Managed Switches

and the computer. You may need to disconnect 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 your computers
local Help and Support functionality and search for “IP Addressing”.
STEP 4 Open 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 5 Enter the switch IP address in the address bar and press Enter. For
example, http://192.168.1.254.
The Managed Switch Login Page displays.
STEP 6 Enter the default login information:
Username is cisco
Default password is cisco (passwords are case sensitive)
STEP 7 If 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 made are saved before exiting from the web-based interface by clicking on the Save icon. 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 Managed Switch Administration Guide for further information.
Use the console port To configure the managed switch:
STEP 1 Connect a computer to the switch console port using the provided
console port cable.
STEP 2 Start a console port utility such as HyperTerminal on the computer.
6
300 Series Managed Switches
STEP 3 Configure the utility with the following parameters: · 115200 bits per
second · 8 data bits · no parity · 1 stop bit · no flow control
STEP 4 Enter a user name and password. User names and passwords are both case
sensitive and alpha-numeric. The default username is cisco, and the default
password is cisco.
STEP 5 If this is the first time that you have logged on with the default
username and password, the Change User Password Page opens. Select Edit, enter
a new administrator password and then select Execute.
CAUTION Make sure that any configuration changes made are saved before
exiting.
You are now ready to configure the switch. Refer to the Cisco Small Business
Managed Switch Administration Guide for further information.
Next Steps · If you are not using DHCP on your network, set the connection
type on the managed 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 Managed 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
ping on a computer running Windows:
STEP 1 Open a command window by using Start > Run and enter cmd. STEP 2 At the
Command window prompt enter ping and the managed
switch IP address. For example ping 192.168.1.254 (the default static IP
address of the managed 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.
Bad Console port connection:
Check the console cable connectors to make sure they are firmly plugged into
the switch and your computer. Make sure the console port utility is configured
with the correct parameters.
Wrong IP address:
Make sure you are using the correct IP address of the switch. You can
determine the status of where you received the current IP address of the
switch from the system LED. You can determine the current IP address of the
switch from the menu CLI through the console port interface, or from your
network administrator.
Make sure that no other device is using the same IP address as the switch.

300 Series Managed Switches
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 standard spanning tree loop detection logic, adding new connections
may take 30 to 60 seconds for the affected interfaces and/or LAN to become
operational.
