To enable DR-based hot swap of a system board, the GLS-configured NIC must satisfy the following conditions.
NIC must be redundant between the system boards
If the redundant NIC is connected to the same system board, you are not allowed to remove the system board using DR.
All parts excluding the failed portion must be in the same configuration as that used before the removal.
If you remove the system board that has previously been replaced, the NIC slot location must be the same as that used before the removal.
