S Commands
This chapter describes the Cisco NX-OS commands that begin with S that are used to manage a Cisco Nexus 2000 Series Fabric Extender from a Cisco Nexus 5600 switch.
serial
To assign a serial number to a Fabric Extender, use the serial command. To remove the serial number, use the no form of this command.

Usage Guidelines
The serial number string you define with the serial command must match the serial number of the Fabric Extender. If you configure a serial number and then you use the fex associate command to associate the corresponding chassis ID to the switch, the association will succeed only if the Fabric Extender reports a matching serial number string.
Configuring a serial number other than that of the given Fabric Extender will force the Fabric Extender offline.
Examples
This example shows how to specify a serial number for a Fabric Extender:
switch# configure terminal
switch(config)# fex 101
switch(config-fex)# serial Rack16_FEX101
This example shows how to remove a serial number from a Fabric Extender:
switch# configure terminal
switch(config)# fex 101
switch(config-fex)# no serial
