Site Requirements - Cisco Catalyst 9300 Series Hardware Installation Manual

Site Requirements

• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
• For switches with the optional 1100 W or 1900 W power supply module, first rack-mount the switch
• Make sure that power supply modules and fan modules are securely inserted in the chassis before moving
• When connecting or disconnecting the power cord on a switch installed with a 350 W or a 715 W power
• Airflow around the switch and through the vents is unrestricted.
• For copper connections on Ethernet ports, cable lengths from the switch to connected devices can be up
• Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or
• Humidity around the switch does not exceed 95 percent.
• Altitude at the installation site is not greater than 10,000 feet.
• Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing

Site Requirements

Planning a proper location for the switch and layout of the equipment rack or wiring closet is essential for
successful system operation. These sections describe some of the basic site requirements that you should be
aware of as you prepare to install your switch, including the following:
• Environmental factors can adversely affect the performance and longevity of your system.
• Install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the
• Equipment that is placed too closely together or that is inadequately ventilated may cause system
• Poor equipment placement can make chassis panels inaccessible and difficult to maintain.
• The switch requires a dry, clean, well-ventilated, and air-conditioned environment.

• 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.
• The pluggable transceiver module minimum bend radius and connector length is met. See the Cisco
pluggable transceiver module documentation for more information.
