Quick Start Guide

Cisco 500 Series Stackable Managed Switches

Welcome

Thank you for choosing the Cisco 500 Series Stackable Managed Switch,
a Cisco network communications devic e. This device is designed to be
operational right out of the box as a standard layer 2 and 3 switch. In the
factory 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

Managed Switch Administration Guide

using web-based system management tools.

Switch

There are two ways to physically install the switch:

• Set the switch on a flat surface.

• Mount the switch in a standard rack (1 rack unit).

Do not deploy the device in a location where any of the following
conditions exist:

High Ambient Temperature—Refer to the following table for the high
ambient temperature rating of each switch.

Reduced Air Flow—Both side panels must be unobstructed to prev ent

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 1 Remove the four screws fr om each side near the front of the switch.

Retain the screws f or re-installation. Do not r emove the f our scr ews
from each side near the back of the switch.

STEP 2 Place 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 Suggested screw size is 6.9 mm (diameter) x 6 mm (height). 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 3 Repeat Step 2 for the other side of the switch.
STEP 4 After the mounting hardware has been securely attached, the

switch is now ready to b e installed into a standard 19-inch rack.

CAUTION For stability , load the rack from the bottom to the t op, with the

2

heaviest devices on the bottom. A top-heavy rack is likely to
be unstable and might tip over.

Connecting Network Devices

To connect the switch to the network:

STEP 1 Connect an Ethernet cable to an Ethernet port of a comput er , printer,

network storage, or other network device.

STEP 2 Connect the other end of the network Ethernet cable to one of the

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

Refer to External Features of the Cisco 500 Series Stackable

Managed Switch for details about the different ports and LEDs on

each switch.

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

the 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.

NOTE 500 Series s w i tches have both s t andard Ethernet and stack ports.

Standard ethernet ports can not be used for stacking. Refer to Stacking

the Switches for additional details.

NOTE The switch can deliver a maximum of 15.4 Watts to any 10/100

Gigabit PoE port. S F500 -24M P, SF500-48MP, SG500X-24MPP, and
SG500X-48MP 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

6 500 Series Stackable Managed Switches

phones, IP cameras , and wireless ac ce s s po ints . The PoE

3

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 b e
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 p ower up a PS E devic e be fore
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 por ts .

Configuring the 500 Series Stackable 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-B ased 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.

500 Series Stackable Managed Switches 7

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 ser ver 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. I f
you are managing the switch through a console port connection, the link
is retained.

To configure the switch through an IP network:

STEP 1 Power on the computer and the switch.
STEP 2 Set 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 3 Open 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 4 Enter the switch IP address in the address bar and press Enter. For

example, http://192.168.1.254.
The Switch Login Page

STEP 5 Enter the default login information:

displays.

• Username is cisco

• Default password is cisco (passwords are case sensitive)

STEP 6 If 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.
