Chapter 2 Switch Installation
Planning a Switch Data Stack (Catalyst
•When connecting or disconnecting the power cord on a switch that is installed above or below a
•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.
•For copper connections on Ethernet ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).
•For cable requirements for SFP+ module connections, see the “Cable and Adapter Specifications” section on page
•Operating environment is within the ranges listed in Appendix A, “Technical Specifications.”
•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.
•Cisco Ethernet Switches are equipped with cooling mechanisms, such as fans and blowers. However, these fans and blowers 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.
These standards provide guidelines for acceptable working environments and acceptable levels of suspended particulate matter:
–Network Equipment Building Systems (NEBS)
–National Electrical Manufacturers Association (NEMA) Type 1
–International Electrotechnical Commission (IEC)
