Caution You can order a replacement fan tray with forward airflow or reverse airflow. Be sure to order the same direction of airflow that is used with the switch. If there is a black stripe across the front of the fan trays and power supplies, the switch is running reverse airflow and you must order a fan tray with reverse airflow. If there is no black stripe across the front of these modules, the switch has forward airflow and you must order replacement modules with forward airflow.

Caution The switch must run with all of its power supply and fan tray modules taking in air from a cold aisle and exhausting air to the hot aisle. If they take in air from a hot aisle, an overtemperature condition can occur and the switch will shut down. If the airflow directions are mixed in the same switch, you will see an error.

Port Connections for the Cisco Nexus 3064 Switch

You can use QSFP+, SFP+, and SFP transceivers with copper or optical cables for the uplink and downlink ports, RJ-45 connectors for the management ports, RJ-45 connector for the console port, and a USB A connector for the USB port.

The four uplink ports support QSFP+ transceivers, each of which can be connected to a single 40-Gigabit optical cable, a 40-Gigabit copper cable, or four 10-Gigabit copper cables with SFP+ transceivers. Table 1-10describes the QSFP+ transceivers and cable connections that you can use.
