Invalid hardware configurations can cause electric or functional problems to the chassis or its
components. Fabric management prevents invalid configurations from powering on.
The following figure shows the location of IOMs in the chassis. The location of each IOM is indicated by
its group number (A, B, or C). These discrete fabric paths are split into two IO Banks, bank one and two.
On the chassis, the IOM slot names are marked A1, A2, B1, B2, C1, and C2.

CMC creates entries in both the hardware log and CMC logs for invalid hardware configurations.
For example:
• An Ethernet MC connected to a Fibre Channel IOM is an invalid configuration. However, an Ethernet
MC connected to both an Ethernet switch and an Ethernet pass-through IOM installed in the same
IOM group is a valid connection.
