Overview, page 1 Overview The Cisco Nexus 9372TX (N9K-C9372TX) and 9372TX-E (N9K-C9372TX-E) switches are 1-rack unit (RU) switches that support 48 10GBASE-T downlink ports (supporting 100-Megabit, 1-Gigabit, and 10-Gigabit Ethernet) and six 40-Gigabit QSFP+ uplink ports (supporting 10-Gigabit and 40-Gigabit Ethernet). These switches also have a 100/1000 network management port, an RS-232 console port for setting the initial switch configuration, and two USB ports for saving or loading switch configurations.
