Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY Specification Guide

Safety warnings appear throughout this publication in procedures that may harm you if performed 
incorrectly. A warning symbol precedes each warning statement. The warnings below are general 
warnings that are applicable to the entire publication.

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. 
Statement 1030

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

Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This 
guide contains important safety information you should know before working with the system. 
Statement 200

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. Statement 1072

These sections describe some of the basic site requirements that you should be aware of as you prepare 
to install your Catalyst 6500 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 inaccessable 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.
