C9300-NM-8X= Cisco 8 Ports Ethernet Expansion Module

The Cisco C9300-NM-8X= is a network expansion module for the Cisco Catalyst 9300 series switches. It provides 10 Gigabit Ethernet (10G) 8 ports for connecting to other network devices or for uplinking to other switches. These ports can be configured for use with either fiber optic or copper cables, depending on the specific module variant. This module is designed to be hot-swappable, so it can be removed and replaced without powering down the switch. It is intended for use in enterprise networks and can be used to expand the capacity and connectivity of a Cisco Catalyst 9300 switch.
