Chapter 2 Preparing for Installation
Site Requirements
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available.
Statement 1024
Warning
Class 1 laser product.
Statement 1008
If you are using your switch as a source for Power over Ethernet (PoE), the following warning applies:
Warning
Voltages that present a shock hazard can exist on inline power circuits if interconnections are made
by using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such
interconnection methods unless the exposed metal parts are in a restricted access location and users
and service people who are authorized to access the 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.
Statement 1072
Site Requirements
These sections describe some of the basic site requirements that you should be aware of as you prepare
to install your Catalyst 4500 E-series switch. Environmental factors can adversely affect the
performance and longevity of your system. Planning a proper location for the switch and layout of your
equipment rack or wiring closet is essential for successful system operation. You should install the
switch in an enclosed, secure area, ensuring that only qualified personnel have access to the switch and
control of the environment. Equipment that is placed too closely together or that is inadequately
ventilated can cause system overtemperature conditions leading to premature component failures. In
addition, poor equipment placement can make chassis panels inaccessible and difficult to maintain.
The switch requires a dry, clean, well-ventilated, and air-conditioned environment. To ensure normal
operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the intake air is too
warm, an overtemperature condition can occur. The switch environmental monitor can then shut down
the system to protect the system components.
Multiple switches can be rack-mounted with little or no clearance above and below the chassis. However,
when mounting a switch in a rack with other equipment, or when placing it on the floor near other
equipment, ensure that the exhaust from other equipment does not blow into the air intake vent of the
switch chassis.
Temperature
Temperature extremes can cause a system to operate at reduced efficiency and cause a variety of
problems, including premature aging and failure of chips, and failure of mechanical devices. Extreme
temperature fluctuations can cause chips to become loose in their sockets. Observe the following
guidelines:
•
Ensure that the system is operating in an environment no colder than 50
°
F (10
°
C) or hotter than 95
°
F
(35
°
C).
•
Ensure that the chassis has adequate ventilation.
•
Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as insulation.
