2 Cisco ESW2 Series Advanced Switches

Welcome

Thank you for choosing the Cisco ESW2 Series Advanced Switch, a Cisco

network communications device. This device is designed to be

operational right out of the box as a standard bridge. In the 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 Cisco ESW2 Series Advanced

Switch Administration Guide, and a PC with a web browser for using web-

based system management tools.

Package Contents

•Cisco ESW2 Series Advanced Switch

•Rackmount Kit

•This Quick Start Guide

This guide will familiarize you with the layout of the switch and describe

how to deploy the device in your network. For additional information, see

www.cisco.com/smb.

Mounting the Cisco 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 high).

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

conditions exist:

High Ambient Temperature—The ambient temperature must not

exceed 104 degrees Fahrenheit (50 degrees Centigrade).

Reduced Air Flow—Front and back vent holes must be unobstructed

to prevent 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 1Remove the four screws from each side near the front of the switch.

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 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 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.

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 may tip over.

Replacing or Reversing the Fan

Mounting the switch in a rack environment requires proper air flow. The fan

module of the ESW2 switch can be reversed to allow for air flow from front

to back, or back to front. The default configuration is flowing from front to

back. To reverse the air flow on your switch, or to replace a defective fan

module, perform the following:

STEP 1Remove the fan tray from the back of the switch by twisting the two

thumb screws until they are loose, then pull the fan tray out of the

switch.

STEP 2Squeeze the two release tabs on the fan module between your

thumb and finger, then pull the module straight up out of the fan

tray.

STEP 3(Optional) To reverse the air flow on the switch, rotate the fan

module 180 degrees.

STEP 4Place the fan module back into the fan tray by lining it up with the

guides and pushing straight down. You should hear an audible click

when it is in place.

STEP 5Insert the fan tray back into the switch, and secure it by tightening

the thumb screws.

STEP 6Check for proper air flow.

DC Electrical Connections

Power installation must be performed by a qualified electrician and

followed by the local and national electrical codes ANSI/NFPA 70 and

Canadian Electrical Coed, Part I, CSA C22.1

WARNING Before powering on the switch for the first time, you must

properly connect the frame of the switch to earth ground. This

is necessary to reduce the effects of external electrical noise,

and help protect the user from electrocution.

The minimum gauge wire for grounding is 18AWG.

WARNING Hazardous voltage or energy may be present on DC power

terminals.

Proper grounding is from an earth connection to the terminal ground screw

on the back of the switch. In the following diagram, 1 is the grounding tab

screwed into place on the grounding lug of the terminal strip, and 2 is the

grounding cable to earth ground.

DC power connections must meet the following criteria:

•Branch circuit over-currant protection must be rated at 20A.

•The circuit breaker must have a contact separation of at least 3mm.

•The DC power rating is -38 — -72 VDC ± 0% 2.5A.

In the following diagram, 1 is the DC power main, and 2 is the circuit

breaker.

Connecting Network Devices

To connect the switch to the network:

STEP 1Connect the Ethernet cable to the Ethernet port of a computer,

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 ESW2 Series Advanced

Switch, page 14 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 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 ESW 550 Series switches have both standard Ethernet and stack

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

Stacking the ESW2 Series Advanced Switch, page 11 for additional

details.

Configuring the ESW2 Series Advanced

Switch

Before You Begin

Verify the managing computer requirements in the product release notes.

The switch can be managed by two different methods: using the web-

based interface, or the Command Line Interface (CLI).

Accessing and Managing Your Switch

Use the console port

To configure the switch 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 1.2.9, 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.

CAUTION Make sure that any configuration changes made are saved

before exiting by issuing the command:

copy running-config startup-config

You are now ready to configure the switch. Refer to the Cisco ESW2

Series Advanced Switch Administration Guide

for further information.

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.

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,

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. 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 up the IP configuration on your computer.

a. If the switch is using the default static IP address of

192.168.1.254, you must chose an IP address 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 Help and Support functionality on your computer and

search for “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)
