If they are the usual black SAS\/SATA ports, or the cage is double-plumbed for U.2 and SAS\/SATA, you want the 05-60003-00 variant instead. Our own cable is dark on both variants and carries no colour code, so check the label: \u003cstrong\u003eDL-A640\u003c\/strong\u003e for this one, \u003cstrong\u003eRSL74-7657\u003c\/strong\u003e for the SAS\/SATA version.
