Welcome
Thank you for choosing the Cisco Small Business 300 Series Managed
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 power up.
Before you begin installing the switch, make sure you have all of the
package contents available, access to the
Cisco Small Business 300
Series Managed Switch Administration Guide
, and a PC with a web
browser for using web-based system management tools.

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).

300 Series Managed Switches 3
NOTE Some switches have a higher temperature rating. The SG300-
10SFP, SG300-52P and SG300-52MP are rated at 113 degrees
Fahrenheit (45 degrees Centigrade), and the SG300-28MP, and SF300-
24MP are rated at 122 degrees Fahrenheit (50 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.
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.

4 300 Series Managed Switches
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 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 Ethernet port light turns green when the connection is active.
Refer to Features of the Cisco Small Business 300 Series
Managed Switch, page 12 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 table for
specific information:
NOTE The switch can deliver a maximum of 15.4 Watts to any 10/100 or
Gigabit PoE port. The 24MP, 28MP, 52P and 52MP models of the switch
can deliver a maximum of 30 Watts to any PoE port.
WARNING The switch is to be connected only to PoE networks without
routing to the outside plant.

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
powered by AC, they could be powered up as a legacy PD
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.
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 Small Business
Managed Switch
Before You Begin
Verify the managing computer requirements in the product release notes.
The switch can be accessed and managed by two different methods; over
your IP network using the web-based interface, or by the Command Line
Interface (CLI) through the console port. Using the console port requires
advanced user skills.
Accessing and Managing Your Switch
Use 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. If
you are managing the switch through a console port connection, the link
is retained.
To configure the switch through an IP network:
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
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 300 Series Managed Switch Administration
Guide
for further information.
Use the console port
To configure the switch by using the console port:
STEP 1Connect a computer to the switch console port using the provided
serial cable.
STEP 2Start a terminal application such as HyperTerminal on the
computer.
STEP 3Configure the utility with the following parameters:
•115200 bits per second (with release 1.2.5 of the firmware,
autobaud detection is enabled by default, so the switch should
detect the speed after you press Enter).

10 300 Series Managed Switches
•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 following message appears:
Please change your password from the default
settings. Please change the password for better
protection of your network. Do you want to change
the password (Y/N) [Y]?
STEP 6Select Y, and enter a new administrator password.
CAUTION Make sure that any configuration changes are saved before
exiting by issuing the command:
copy running-config startup-config
You are now ready to configure the switch. Refer to the
Cisco Small
Business 300 Series Managed Switch Administration Guide
for further
information.
NOTE If you are not using DHCP on your network, set the IP address type
on the switch to Static and change the static IP address and subnet
mask to match your network topology. Failure to do so may result in
multiple switches using the same factory default IP address of
192.168.1.254.
