Cisco Nexus 3016 Switch
Fan Tray for the Cisco Nexus 3016 Switch
The Cisco Nexus 3016 switch ships with one fan tray, which is the same fan tray used by the Cisco Nexus
3064 switch (part number N3K-C3064-FAN for forward airflow or N3K-C3064-FAN-B for reverse
airflow). You can hot swap the fan tray during operations but must replace it within two minutes or the
switch can reach an overtemperature condition and shut down.
3064 switch (part number N3K-C3064-FAN for forward airflow or N3K-C3064-FAN-B for reverse
airflow). You can hot swap the fan tray during operations but must replace it within two minutes or the
switch can reach an overtemperature condition and shut down.
Caution
You can order a replacement fan tray with forward airflow or reverse airflow. Be sure to order the same
direction of airflow as 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 3016 Switch
You use QSFP+ transceivers with the 16 networking ports used for uplinking and downlinking. For
low-cost connections to switches in the same or adjacent racks, use QSFP+ transceivers with copper
cables. For long distance connections, use the QSFP transceivers connected to optical cables.
