Replacement for #EMX0; no upgrade path from Gen3, but both drawer types can coexist. Gen4 drawer cables are not interchangeable with Gen3 cables. Only four #EC2S, #EC2U or #EC72 adapters can run in SR-IOV mode per fan-out module. Not supported on the S1012.

Before you order ENZ0

An expansion drawer adds slots or drive bays when the server itself is full. It is often the difference between upgrading a Power 10 and replacing it.
