EIOM replacement
Use the following procedures to remove and install the Ethernet I/O module (EIOM).

via ports on the EIOM located at the rear of the enclosure. The top Phy maps to port one of the system LOM,
the bottom Phy maps to port two of the system LOM.
The ports are labeled sequentially from left to right.
