Quick Start Guide

Cisco 350X Series Managed Switches

Welcome

1

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.

Package Contents

• Your Cisco 350X Series Managed Switch

• Power Cord

• Rack-Mount Kit and Rubber Feet

• DB-9 to RJ45 Serial Cable

• Quick Start Guide

• Pointer Card with China RoHS

• Technical Support Contacts

• EU Directives 1999/5/EC Compliance Information (for EU SKU only)

Before You Begin

Before you begin the installation, make sure that you have the following:

• RJ-45 Ethernet cables for connecting network devices. A category 6a
and higher cable is required for 10G ports; a category 5e and higher
cable is required for all other ports.

• Console cable for using the console port to manage your switch.

• Tools for installing the hardware. The rack-mount kit packed with the

switch contains four rubber feet for desktop placement, and two
brackets and twelve screws for rack-mounting. If the supplied screws
are lost, use replacement screws in the following size:

– Diameter of the screw head: 6.9 mm

– Length of face of screw head to base of screw: 5.9 mm

– Shaft diameter: 3.94 mm

• Computer with Internet Explorer (version 9.0, 10.0, 11.0), or Firefox

2

(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.
Refer to Cisco 350X Series Switch Features for details about the
different ports and LEDs on each switch.

TEP 3 Repeat Step 1 and Step 2 for each device that you want to

S

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:

CAUTION Consider the following when connecting switches capable of

454

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.
