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.

300 Series Managed Switches 3
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 rack–mount
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:
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 wall-
mounting.
Connecting Network Devices
To connect the managed 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 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 9
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 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).

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.
The switch works with Cisco Small Business network tools and services
including the Cisco FindIT Network Discovery Utility that enables you to
automatically discovers all supported Cisco Small Business devices in the
same local network segment as your PC. You can get a snapshot view of
each device or launch the product configuration utility to view and
configure the settings. For more information, see www.cisco.com/go/findit.
Accessing and Managing Your Switch Using the Web-
Based 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 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 chose an IP address in the range of
192.168.1.1-192.168.1.253 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
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 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 Managed Switch Login Page
displays.
STEP 6Enter the default 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 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 1Connect a computer to the switch console port using the provided
console port cable.
STEP 2Start a console port utility such as HyperTerminal on the computer.
STEP 3Configure the utility with the following parameters:
•115200 bits per second
•8 data bits
•no parity
•1 stop bit
•no flow control
STEP 4Enter 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 5If 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 1Open a command window by using Start > Run and enter cmd.
STEP 2At 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 9
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.
Features of the Cisco Small Business
Managed Switch
This section describes the exterior of the managed switches including
ports, LEDs, and connections.
Front Panel Ports
The ports and LEDs are located on the front 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.
MiniGBIC (if present)—The miniGBIC (gigabit interface converter) ports are
connection points for miniGBIC modules, so the managed switch can
uplink to other switches by using optical fiber.
•MiniGBIC ports are compatible with Cisco miniGBIC modules MGBSX1,
MGBLH1, MGBLX1, MGBBX1, MFELX1, MFEFX1, and MFEBX1, as well as
other brands of miniGBIC modules.
• MiniGBIC interface is a combination port, shared with one other RJ-45
interface. When the MiniGBIC is active, the adjacent RJ-45 port is
disabled.
•The LEDs of the corresponding RJ-45 port light to respond to the
miniGBIC interface traffic.
