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
•Product CD
•Serial Cable
•Rubber Feet
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.

Cisco ESW2 Series Advanced Switches 5
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.

Cisco ESW2 Series Advanced Switches 7
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.

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.

10 Cisco ESW2 Series Advanced Switches
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)

Cisco ESW2 Series Advanced Switches 11
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.
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 ESW2 Series Advanced 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 ESW2 Series Advanced Switch
The 550 series switches can be configured in a stack. The 350 series
switches do not have stack capability. Before configuring the switches as a
stack, refer to the Cisco ESW2 Series Advanced Switch Administration
Guide for additional details. Refer to the front panel graphics in External
Features of the ESW2 Series Advanced Switch, page 14 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:

12 Cisco ESW2 Series Advanced Switches
TIP The default stack ports on the 550X are XG3/S1 and
XG4/S2. If the correct module is plugged into XG3/S1 and
XG4/S2, the switch should be able to detect the connection
and configure the speed according to the module capability
without any manual configuration. The 5G/S1 and 5G/S2
interfaces on the 550X need to be configured manually via
the CLI or web-based interface in order to utilize these ports
as stack ports.
WARNING The stack ports must be either configured with the same port
speed or have the same speed capability on the module/cable
plug in. If the port speed is configured as auto, then the module
plugged into these two ports will need to have the same speed
capability, otherwise the switch will not be able to form as a
stack with multiple units.
By default, the switch is in stack mode with a stack Unit ID automatically
assigned. A stack can have up to four 550X models.
Switches in the same stack are connected together through their stack
ports. Depending on the type of stack ports and the desired speed, you
may need regular Cat5 or better Ethernet cables and/or Cisco approved
modules or cables for the 550 Series switches.
The default stack ports on a switch function as regular Ethernet ports only
by configuring them to do so, or if the switch is configured to operate in
standalone mode. You cannot mix the stack speeds between the switches
or ports.
If you manually assign a Unit ID to one unit, you should manually assign Unit
IDs to
all units. Using both system-assigned and manually-assigned IDs in
your network can impact system performance.
Changing the stack mode of a switch requires a reboot of the switch.

Troubleshoot Your Connection
If you cannot access your switch from the web-based interface, the switch
might not be reachable from your computer. You can test network
connections by using ping on a computer running Windows:
STEP 1Open the Terminal application.
STEP 2Enter the ping command and the switch IP address. For
example ping 192.168.1.254 (the default IP address of the switch).
If you can reach the switch, you should get a reply similar to the
following:
Pinging 192.168.1.254 with 32 bytes of data:
Reply from 192.168.1.254: bytes=32 time<1ms TTL=128
If you cannot reach the switch, you should get a reply similar to the
following:
Pinging 192.168.1.254 with 32 bytes of data:
Request timed out.
Possible Causes and Resolutions
Bad Ethernet connection:
Check the LEDs for proper indications. Check the connectors of the
Ethernet cable to ensure they are firmly plugged into the switch and
your computer.

14 Cisco ESW2 Series Advanced Switches
Bad console port connection:
Check the console cable connectors to make sure they are firmly
plugged into the switch and your computer. Make sure the terminal
application is configured with the correct parameters.
Wrong IP address:
Make sure you are using the correct IP address for the switch. You can
determine the status of how the switch obtained the current IP address
by observing the system LED. You can determine the current IP
address of the switch through the console port interface by using the
CLI, or from your network administrator.
Make sure that no other device is using the same IP address as the
switch.
No IP route:
If the switch and your computer are in different IP subnets, you need
one or more routers to route the packets between the two subnets.
Unusually long access time:
Most connections will be available in a few seconds. Due to the
standard spanning tree loop detection logic, adding new connections
might take 30 to 60 seconds for the affected interfaces and/or LAN to
become operational.

RJ-45 Ethernet Ports—Use these ports to connect network devices, such
as computers, printers, and access points, to the switch. Standard Ethernet
ports can not be used to stack the switches.
SFP/SFP + (if present)—The small form-factor pluggable (SFP) are
connection points for modules, so the switch can link to other switches.
These ports are also commonly referred to as miniGigaBit Interface
Converter (miniGBIC) ports. The term SFP will be used in this guide.
•SFP ports are compatible with Cisco 1G modules MGBT1, MGBSX1,
MGBLH1, MGBLX1, MGBBX1; and 100M modules MFELX1, MFEFX1, and
MFEBX1, as well as other brands of modules.
•SFP+ interface (XG1-XG4) support the following modules:
Cisco SFP+ 10G Optical Modules:
–SFP-10G-SR
–SFP-10G-LRM
–SFP-10G-LR
Cisco SFP+ Copper Twinex Cable:
–SFP-H10GB-CU1M
–SFP-H10GB-CU3M
–SFP-H10GB-CU5M
NOTE SFP+ modules are backward compatible with the 1G modules
only, not the 100M SFP modules. The SFP interface supports the 1G and
100M SFP module, and the SFP+ interface supports the 1G and 10G
modules. The 5G interface supports Copper Twinex Cable.
