NEW Cisco N3K-C31128PQ-10GE 96x 10GB SFP+ 8x 40GB QSFP+ Front-to-Back Air Switch

The Cisco N3K-C31128PQ-10GE is a 2RU Nexus 31128PQ with 96x 10 Gigabit SFP+ ports and eight fixed 40 Gigabit QSFP+ uplinks. 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.

Capacity is 2.5 Tbps with a 1.4 Bpps forwarding rate, a 12 MB shared packet buffer, and a 288,000-entry MAC address table. The switch carries 64 GB SSD 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 N9K-C9300-FAN3-B (port-side exhaust) or N9K-C9300-FAN3 (port-side intake) - note the N9K suffix logic is reversed on this model. Power supply choices are the N9K-PAC-650W-B AC (port-side exhaust) or N9K-PAC-650W AC (port-side intake). The N9K-C9300-ACK rack kit fits this chassis. Check the fitted fan and power supply part numbers against your row's airflow before racking the switch.

A tested seller refurbished N3K-C31128PQ-10GE is also available at a lower price.

This switch is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
