• For chassis that only contain FEMs, all four FEMs must connect to the same chassis with the FSEs. The fabric B FEMs cannot be connected to FSEs in a different chassis as the fabric A FSEs. Recommended connection order Any QSSFP28-DD port on the MX9116n can be used for any purpose. The table below describes the recommended port order for connecting chassis with Fabric Expander Modules (FEMs) to the FSE. The table contains references IOMs in fabric A, but the same guidelines apply to IOMs in fabric B. Table 19.

connected to FSEs in a different chassis as the fabric A FSEs.
Recommended connection order
Any QSSFP28-DD port on the MX9116n can be used for any purpose. The table below describes the recommended port order for
connecting chassis with Fabric Expander Modules (FEMs) to the FSE. The table contains references IOMs in fabric A, but the same
guidelines apply to IOMs in fabric B.
