Reduced AirFlow—Bothsidepanelsmust be unobstructedtoprevent

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 1Removethefourscrewsfromeach sidenear thefrontof theswitch.

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 Suggestedscrewsizeis6.9mm(diameter)x6mm(height).Ifyour

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.

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 1ConnectanEthernetcabletoanEthernetportofacomputer,printer,

network storage, or other network device.

STEP 2Connect 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, page16 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 switch.

NOTE Cisco strongly recommends using Cat5 orbetter 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 switches have both standard Ethernet and stack ports.

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

the Switches, page10 for additional details.

6 500 Series Stackable Managed Switches

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

Gigabit PoE port. SF500-24MP, 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 Considerthefollowingwhenconnectingswitchescapableof

supplying PoE:

The PoE models of the switches are PSE (Power Sourcing

Equipment) that are capable of supplying DC power to

attachingPD(PoweredDevices).ThesedevicesincludeVoIP

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

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 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-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.

8 500 Series Stackable Managed Switches

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,

youraccess tothe switchwill belost. You mustenter the newIPaddress

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.UsethecomputerHelpandSupportfunctionalitytosearchfor“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.

500 Series Stackable Managed Switches 9

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 500 Series Stackable 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 by 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 1.2.7 of the firmware,

autobaud detection is enabled by default, so the switch should

detect the speed after you press Enter).

•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.

10 500 Series Stackable Managed Switches

CAUTION Make sure that any configuration changes are saved before

exiting by issuing the command:

copy running-config startup-config

You are ready to configure the switch. Refer to the

Cisco 500 Series

Stackable 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.

Stacking the Switches

Before configuring the switches as a stack, refer to the Cisco 500 Series

Stackable Managed Switch Administration Guide for additional details.

Refer to the front panel graphics in External Features of the Cisco 500

Series Stackable Managed Switch, page16 to help with the stack port

descriptions and supported modules.

The following graphic shows the stack ports to assist in connecting the

devices in a stack:
