Cisco Nexus 2148T
The Cisco Nexus 2148T FEX is a 1 RU device that acts as a remote I/O module on the Cisco Nexus 5000
Series switch. All device configurations are managed on the switch and configuration information is
downloaded through inband communication to the FEX. You can use this FEX with the Cisco Nexus
5000 Series switch. The FEX software ships with the Cisco Nexus 5000 Series switch software. The FEX
downloads the software image from the switch the same way that a module would download it from the
supervisor in a modular chassis.
