Initiate the module replacement workflow

To initiate the module replacement workflow, use the module replacement sfs_node_replace.py command from the master IOM. Enter the service tag information as the parameters in the module replacement command. You can find the service tag information in the Express Service Tag on the IOMs. To view the information, pull out the information tag in front of the system.

Before initiating the workflow, the system prompts for the admin credentials.

Run the module replacement command from the Linux prompt. To display the service tag of an MX Ethernet I/O module, use the show smartfabric cluster member command in SmartFabric or Full Switch mode. 
admin@MX9116N-A2:~$ sfs_node_replace.py NewServiceTag oldServiceTag
  • NewServiceTag - Service tag of the new IOM
  • OldServiceTag - Service tag of the faulty IOM

If the IOM is not part of the SmartFabric, the system displays the following error: 

Enter the Username for the Admin: admin

Password:

No Fabric found for specified nodes. Please recheck and issue this command again.
