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.
◦ Access to the rear of the rack is sufficient for connecting FlexStack cables to stacked switches, or connecting the optional
Cisco Redundant Power Supply (RPS) 2300.
• 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 switches with the optional 1025-W power-supply module, first rack-mount the switch before installing the power-supply
module.
• Make sure power-supply modules are securely inserted in the chassis before moving the switch.
• When connecting or disconnecting the power cord on a switch that is installed above or below a 1025-W power supply-equipped
switch, you might need to remove the module from the switch to access the power cord.
• Airflow around the switch and through the vents is unrestricted.
• For the Catalyst 2960X-24PSQ-L switches: Allow these clearances:
• Top and bottom: 1.75 in. (44.44 mm)
• Back of switch: 3 in. (76.19 mm)
• 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 95 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).
• 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.
