2 Cisco 350X Series Managed Switches
Welcome
Thank you for choosing the Cisco 350X Series Managed Switches. The
switches are designed to be operational right out-of-the-box as standard
layer 2 and 3 switches. Using the default configuration, your switch
forwards packets between the connecting devices after power up.
This guide familiarizes you with the switch layout and describes how to
deploy the switch in your network. For additional information, see
www.cisco.com/go/350xswitches.

• Computer with Internet Explorer (version 9.0, 10.0, 11.0), or Firefox
(version 36.0, 37.0 or higher), or Chrome (version 40,41,42 or higher) for
using the web-based interface or the console port to manage your
switch.
Mounting the Cisco 350X Series Switches
Your switch can be installed in the following ways:
• Place the switch on a flat surface. To place the switch on a desktop,
install the four rubber feet (included) on the bottom of the switch.
• Mount the switch in a standard rack (1 rack unit high).
Placement Tips
Do not deploy the switch in a location where any of the following
conditions exist:
•Ambient Temperature—To prevent the switch from overheating, do not
operate it in an area that exceeds an ambient temperature of 122°F
(50°C).
•Air Flow—Be sure that there is adequate air flow around the switch.
• Mechanical Loading—Be sure that the switch is level and stable to
avoid any hazardous conditions.
• Circuit Overloading—Adding the switch to the power outlet must not
overload that circuit.
Rack Mounting
You can mount the switches in any standard size, 19-inch (about 48 cm)
wide rack. The switch requires 1 rack unit (RU) of space, which is 1.75
inches (44.45 mm) high.
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.

To install the switch into a 19-inch standard chassis:
STEP 1 Place one of the supplied brackets on the side of the switch so that
the four holes of the brackets align to the screw holes, and then use
the four supplied screws to secure it.
STEP 2 Repeat the previous step to attach the other bracket to the opposite
side of the switch.
STEP 3 After the brackets are securely attached, the switch is now ready
to be installed into a standard 19-inch rack.
Connecting Network Devices
To connect the switch to the network:
STEP 1 Connect an Ethernet cable to the Ethernet port of a computer,
printer, network storage, or other network devices.
STEP 2 Connect the other end of the Ethernet cable to one of the
numbered Ethernet ports of the switch.
The Ethernet port light turns green when the connection is active.

TEP 3 Repeat Step 1 and Step 2 for each device that you want to
connect to the switch.
NOTE A category 6a and higher cable is required for 10G ports; a category
5e or higher cable is required for all other ports. 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 the 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:
*60-Watt PoE extends the IEEE Power of Ethernet Plus standard to double
the power per port to 60 Watts.

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 350X Series Switches
Before You Begin
The switch can be accessed and managed by two different methods; over
your IP network using the web-based interface, or by using the switch’s
command-line interface through the console port. Using the console port
requires advanced user skills.
These are the default settings used when configuring your switch for the
first time.
Parameter Default Value
Username cisco
Password cisco
LAN IP 192.168.1.254
454
Cisco 350X Series Managed Switches 7
Configuring Your Switch Using the Web-based Interface
To access the switch with a web-based interface, you must know the IP
address that the switch is using. The switch uses the factory default IP
address of 192.168.1.254, with a subnet of /24.
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 a steady green (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
that 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 using the web-based interface:
STEP 1 Power on the computer and your switch.
STEP 2 For Cisco 350XG switches, connect the computer to the OOB port
found on the front panel. For Cisco 350X switches, connect the
computer to any network port.
STEP 3 Set up the IP configuration on your computer.
a. If the switch is using the default static IP address of
192.168.1.254/24, you must choose an IP address for the
computer in the range of 192.168.1.2 to 192.168.1.253 that is
not already in use.
b. If the IP addresses will be assigned by DHCP, make sure that
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 that
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
ActiveX 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.

Configuring Your Switch Using the Console Port
To configure the switch using the console port:
STEP 1 Connect a computer to the switch console port using the supplied
console cable.
STEP 2 Start a console port utility such as HyperTerminal on the computer.
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 username and password. The default username is cisco,
and the default password is cisco. Usernames and passwords are
both case sensitive.
If 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 5 Enter Y, and set a new administrator password.
NOTE Password complexity is enabled by default. The password
must comply with the default complexity rules.
CAUTION Make sure that any configuration changes made are saved
before exiting.
You are now ready to configure the switch. Refer to www.cisco.com/go/
350xswitches to locate the CLI Guide for your switch.
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.

Stacking the Cisco 350XG Series Switches
Before configuring the switches as a stack, refer to the Administration
Guide for additional details. Refer to the front panel graphics in Cisco
350X Series Switch Features to help with the stack port descriptions and
supported modules.
By default, the ports on a switch function as regular Ethernet ports, except
if you configure them to do stacking. You cannot mix the stack speeds
between the switches or ports.
WARNING Stack ports must be either configured with the same port
speed or have the same speed capability on the module or
cable plug in. If the port speed is configured as auto, then the
module plugged into these two ports will need to have the
same speed capability, otherwise the switch will not be able to
form as a stack with multiple units.
A stack can have up to four Cisco 350XG series switches in it. Any 10G
port of the switch can be used for stacking. The switch can only be
stacked without Mesh topology.
The switches in the same stack are connected together through their stack
ports. Depending on the type of stack ports and the desired speed, you
may need Cat6a Ethernet cables and/or Cisco approved modules or
cables for the Cisco 350XG switches.

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 selecting Start > Run and enter cmd.
STEP 2 At the Command window prompt, enter ping and the switch IP
address. For example, ping 192.168.1.254 (the default static IP
address of the 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
The Switch is not Powering on
• Verify the power cord is plugged firmly into the switch and into the
power outlet.
• Verify that the power outlet is active.
• Verify that the computer is on.
• Replace the power adapter, before replacing the switch, if the situation
continues.
Bad Ethernet connection
• Check the LEDs for proper indications. See Front Panel for details.
• Check the connectors of the Ethernet cable to ensure that they are
firmly plugged into the switch and your computer.
• Use a different Ethernet cable or port.
Bad Console port connection
• Verify the console cable connectors are firmly plugged into the switch
and your computer.
• Verify the console port utility is configured with the correct parameters.
16 Cisco 350X Series Managed Switches
IP Addressing Issues
• The Cisco switches can also be accessed by the Cisco FindIT Network
Discovery Utility that automatically discovers all Cisco Small
Business devices in the same local network segment as your computer.
You can view device information including the current IP address,
download the latest firmware for the device, or launch the product
configuration utility to view and configure the settings. For more
information, see www.cisco.com/go/findit.
• Verify that you are using the correct IP address of the switch. Determine
the current IP address of the switch from the CLI through the console
port, Cisco FindIT, or from your network administrator. The System LED
provides an indication of where the switch received the IP address (See
Front Panel 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 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.
