Safety Warnings
This section includes the warning statements relating to basic installation. Read this section before you start
the installation procedure.
Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces,
and watches). Metal objects will heat up when connected to power and ground and can cause serious burns
or weld the metal object to the terminals. Statement 43
Warning
Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and
equipment damage. Statement 48

1001
Warning
Read the installation instructions before connecting the system to the power source. Statement 1004
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to
ensure that the system remains stable. The following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
unit in the rack.
Statement 1006
Warning
Class 1 laser product. Statement 1008
Warning
This unit is intended for installation in restricted access areas. A restricted access area can be accessed only
through the use of a special tool, lock and key, or other means of security. Statement 1017
Warning
The plug-socket combination must be accessible at all times, because it serves as the main disconnecting
device. Statement 1019

Note
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or
view directly with optical instruments. Statement 1051
Warning
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work
on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard
practices for preventing accidents. Use the statement number provided at the end of each warning to locate
its translation in the translated safety warnings that accompanied this device. Statement 1071
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are
made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection
methods, unless the exposed metal parts are located within a restricted access location and users and service
people who are authorized within the restricted access location are made aware of the hazard. A restricted
access area can be accessed only through the use of a special tool, lock and key or other means of security.

Tools and Equipment
Obtain these necessary tools:
• A Number-2 Phillips screwdriver to rack-mount the switch
Installation Guidelines
When determining where to install the switch, verify that these guidelines are met:
• Clearance to the switch front and rear panel meets these conditions:
• Front-panel LEDs can be easily read.
• Access to ports is sufficient for unrestricted cabling.
• AC power cord can reach from the AC power outlet to the connector on the switch rear panel.
• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
• Airflow around the switch and through the vents is unrestricted.
• Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or
multirack assembly, the temperature around it might be greater than normal room temperature.
• Humidity around the switch does not exceed 90 percent.
• Altitude at the installation site is not greater than 10,000 feet.
• For 10/100/1000 fixed ports, the cable length from a switch to a connected device cannot exceed 328
feet (100 meters).

Switch Installation
Tools and Equipment
• Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing
contaminant buildup inside the chassis, which can result in system malfunction. You must install this
equipment in an environment as free from dust and foreign conductive material (such as metal flakes
from construction activities) as is possible.
Verifying Switch Operation
Before you install the switch in a rack, on a wall, or on a table or shelf, power on the switch and verify that
it passes POST.
To power on the switch, plug one end of the AC power cord into the switch AC power connector, and plug
the other end into an AC power outlet.
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch
functions properly. LEDs can blink during the test. The SYST LED blinks green, and the other LEDs remain
solid green.
When the switch completes POST successfully, the SYST LED remains green. The other LEDs turn off and
then reflect the switch operating status. If a switch fails POST, the SYST LED turns amber.
POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.
After a successful POST, unplug the power cord from the switch and install the switch in a rack, on a wall,
on a table, or on a shelf.
Installing the Switch
Rack-Mounting
Installation in other than 19-inch racks requires a bracket kit not included with the switch.
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to
ensure that the system remains stable. The following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
unit in the rack.
