Chapter 1 Overview of the Cisco Nexus 3000 Series Switches
Cisco Nexus 3132Q 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.
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.
Transceiver and Cabling Options for the Cisco Nexus 3132Q Switch
The Cisco Nexus 3132Q has 32 QSFP+ ports. QSFP+ technology allows a smooth transition from 10 to
40 Gigabit Ethernet infrastructures in data centers. Each of the Cisco Nexus 3132Q switch’s QSFP+
ports can operate in either native 40 Gigabit Ethernet mode or 4 x 10 Gigabit Ethernet mode. This switch
supports both fiber and copper cabling solutions for these two modes.
For low-cost cabling, copper-based 40-Gbps Twinax cables can be used, and for longer cable reaches,
short-reach optical transceivers are excellent. Connectivity can be established from the QSFP+ ports to
10 Gigabit Ethernet switches or hosts using a splitter cable that has a QSFP+ transceiver on one end and
four SFP+ transceivers on the other end. Similar capability can be achieved on the fiber solution by using
QSFP+ SR4 transceivers on both ends and procuring third-party fiber splitter MPO-to-LC cables.
Table 1-14 lists the QSFP transceiver types supported.
