Dell EMC SmartFabric OS10 User Guide Release 10.5.1

Replace an IOM in SmartFabric

To replace an IOM that is part of a SmartFabric:

1. Physically remove the faulty IOM and insert the new IOM, see Remove and replace the IOM.
2. Verify the firmware version and configure the IOM settings, see Verify and configure IOM settings.
3. Identify the master IOM connected in the PowerEdge MX chassis, see Identify the master IOM.
4. Initiate the replacement workflow from the master IOM using the module replacement command, see Initiate the module replacement workflow. The module replacement command is a Linux command that must be run from the Linux shell.
5. Connect the cables to the new IOM, see Connect the cables to the new IOM.

Master and member IOMs: A single MX chassis supports four Ethernet IOMs, where one IOM is the master and the remaining three are members. In a multiple chassis environment, of all the IOMs connected in a scalable fabric, one IOM is the master and the remaining are members.

When an IOM is replaced, run the sfs_node_replace.py script to push the existing IOM configurations that are done through the smart fabric mode GUI to the new IOM.
