Cisco 550X Series Stackable Managed Switches

Welcome

1

Thank you for choosing the Cisco 550X Series Stackable Managed Switch,
a Cisco network communications device. This device is designed to be
operational right out-of-the-box as a standard layer 2 and 3 switch. In the
default configuration, it will forward packets between connecting devices
after power up.

This guide familiarizes you with the layout of the switch and describes how
to deploy the switch in your network. For additional information, see

www.cisco.com/go/550xswitches.

Package Contents

• Cisco 550X Series Stackable 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
or higher cable is required for 10G ports; a category 5e or 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.

• Computer with Internet Explorer (version 9.0, 10.0, or 11.0), Mozilla
Firefox (version 36.0, 37.0, or higher), or Google Chrome (version
40,41,42, or higher) for using the web-based interface or the console
port to manage your switch.

Mounting the Cisco 550X Series Stackable

Managed Switches

There are two ways to physically install the switch:

• 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.

These switches must be supplied by power from the building in which
they are used or from UL listed information technology (ITE) equipment. For
assistance with obtaining a power supply, contact your Cisco
Representative.

Rack Mounting

You can mount the switch 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 the

four holes of the brackets align to the screw holes, and then use the
four supplied M4 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 as shown here.

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 LED of the port lights if
the device connected is active.

The Ethernet port light turns green when the connection is active.

Features for details about the different ports and LEDs on each

switch.

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

connect to the switch.

OTE A Category 6A or higher cable is required for 10G ports; a

N

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
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:
