I don't think anyone said anything about modifying your equipment, Marty.
Ideally, the PDUs that provide the NEMA 5-20R or 5-15R receptacles in the
rack should have the NEMA L5-20P on their input cord.
Then, all that remains is to make sure that the total load being connected
to each PDU does not exceed 18A max or 15A continuous. (You should
always run a circuit with 25% continuous headroom and 10% max draw
headroom in order to allow for line losses, etc.).
