You can view details of the IOM and Flex Modules on the CMC RACADM, and Chassis Health, I/O Module Status, and I/O Module
Overview pages.
CMC reports information about the ex modules in the IOA by reading the ex module information during its initial negotiation with the IOA.
The reading happens by sending XML commands during the initial negotiation. CMC saves the ex module information in the shared
memory. There can be a maximum of two ex modules:
• FlexIO Module 1
• FlexIO Module 2
All IOM software that support the command revision 4 support the Flex IO module information XML command. CMC sends the ex module
information only if the command revision is 4 or later. Any failure to read the ex module information is stored in the Chassis Log.
The ex module information can have the following ve values:
• 4x10G Base-T FlexIO Module = 0
• 4x10G SFP+ FlexIO Module = 1
• 2x40G QSFP+ FlexIO Module = 2
• 4xFC FlexIO Module = 3
• No ex module installed = 4
Any value greater than 4 is considered invalid. CMC displays as “Invalid/Unknown” ex module.
The modes of the IOM are as follows:
• Standalone
• Stacking
• PMux
• Full Switch
You can view the IOM mode as a tool tip when you select IOM on the Chassis Health, I/O Module Status, and I/O Module Overview
pages.
