Installation Guidelines
Installation Guidelines
Before installing the switch, verify that these guidelines are met:
•For Ethernet ports and 1000BASE-T SFP module ports, cable lengths from the switch to connected
devices can be up to 328 feet (100 meters).
•For cable requirements for SFP+ and SFP module connections, see the “Cable Pinouts” section on
page B-7.
•Operating environment is within the ranges listed in AppendixA, “Technical Specifications.”
•Front-panel indicators can be easily read, and access to ports is sufficient for unrestricted cabling.
•AC power cord reaches from the power outlet to the connector.
•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.
•Airflow around the switch and through the vents is unrestricted.
Note If the switch is installed in a closed or multirack assembly, the temperature around it might be
greater than normal room temperature.
•Before you connect the switch to a power source, note the power consumption specifications in
Appendix A, “Technical Specifications.”
Verifying Switch Operation
Before installing the switch in a rack, on a wall, on a table, or on a shelf, you should power the switch
and verify that the switch passes the power-on self-test (POST).
To power on the switch, see Chapter3, “Installing and Removing AC and DC Input Power Supply and
Fan Modules.”
When the switch begins POST, the System LED blinks green, and the other LEDs remain green. When
the switch passes POST, the System LED becomes green. The other LEDs turn off and return to their
operating status. If the switch fails POST, the System LED is amber.
Note Contact Cisco Systems immediately if your switch fails POST.
