Cisco Nexus 3064 Switch
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 1-10
describes the QSFP+ transceivers and cable connections that you can use.
The 48 downlink ports support SFP+ and SFP transceivers that are either connected to copper cables or
can be connected to optical cables.
Table 1-11
describes the SFP+ transceivers and cable connections
that you can use.
Table 1-12
describes the SFP transceivers and cable connections that you can use.
