Quick Start Guide
Cisco ESW2 Series Advanced Switches
Welcome
1
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 webbased 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 1 Remove 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 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 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 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 1 Remove 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 2 Squeeze the two release tabs on the fan module between your
thumb and finger, then pull the module straight up out of the fan
tray.

module 180 degrees.
STEP 4 Place 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.

TEP 5 Insert the fan tray back into the switch, and secure it by tightening
the thumb screws.
STEP 6 Check 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.

• 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 1 Connect the Ethernet cable to the Ethernet port of a computer,
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 ESW2 Series Advanced
Switch, page14 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 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 webbased interface, or the Command Line Interface (CLI).
