EIOM replacement
Use the following procedures to remove and install the Ethernet I/O module (EIOM).
The ThinkAgile CP Compute Block appliances offer connectivity to the LOM (LAN on motherboard) of each
node 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.

4. Disconnect the power cords and all external cables from the rear of the enclosure.
5. If the cable management arm is installed, remove it (see
