A network module is a hardware component that slots into a compatible switch, router, or chassis to add or extend its functionality. Common types include uplink modules (which add higher-speed or additional uplink ports to a fixed switch), line cards (which populate the port slots of a modular chassis switch or router with a specific port type and speed), Fibre Channel expansion modules (which add native FC ports to an Ethernet switch for SAN connectivity), and management modules (which provide the control plane, management interface, and supervisor functions for a multi-slot chassis). We stock all of these types across brands including Cisco (Nexus, Catalyst, and UCS modules), Dell (PowerConnect and PowerSwitch add-on modules), HPE (FlexNetwork and FlexFabric modules), Juniper (EX and MX Series MIC and PIC cards), Extreme Networks (Alpine and Summit modules), Supermicro (AOC add-on cards), and Brocade Foundry Networks (XFP and expansion modules).
