•
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.
Verifying Switch Operation
Before you install the switch in a rack, on a wall, or on a table or shelf, power on the switch and verify that
it passes POST.
To power on the switch, plug one end of the AC power cord into the switch AC power connector, and plug
the other end into an AC power outlet.
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch
functions properly. LEDs can blink during the test. POST lasts approximately 1 minute. When the switch
