The Cisco N3K-C3432D-S is a 1RU 32-port 400 Gigabit QSFP-DD switch; each port breaks out to 2x 200GB, 4x 100GB, 4x 50GB, 4x 25GB, or 8x 50GB, with two 100/1000M SFP ports. It suits top-of-rack and aggregation roles in data center and campus networks. This unit is the front-to-back (port-side intake) airflow version: cooling air enters at the port side and leaves through the fans and power supplies. It runs Cisco NX-OS with the usual Nexus toolset for automation and monitoring.
Capacity is 25.6 Tbps with a 7.2 Bpps ingress forwarding rate, a 70 MB dynamic packet buffer, and a 120,000-entry MAC address table. The switch carries 16 GB DRAM and 128 GB bootflash.
Fans and power supplies are hot-swappable and redundant, and every module in one chassis must share the same airflow direction. Fan choices are the NXA-FAN-35CFM-PE (port-side exhaust) or NXA-FAN-35CFM-PI (port-side intake). Power supply choices are the NXA-PAC-1500W-PE AC (port-side exhaust) or NXA-PAC-1500W-PI AC (port-side intake). Check the fitted fan and power supply part numbers against your row's airflow before racking the switch.
For a deep-buffer 100GB platform, see the Nexus 3636C-R.
