939 What power cable do I need for the Avid HDX card for the Echo Express III-D, III-R, or xMac Pro Server?Feb-16-18
The 3-card cable for the Mac Pro that Avid includes with HDX card also works in the Sonnet's Echo Express III-D, III-R and xMac Pro Server. Just replace the cable that is inside the chassis with the Avid cable. If you need a replacement cable, Sonnet has made a power cable for a single Avid HDX card that is compatible with these chassis. The part number is TCB-HDXB and is available from Sonnet or Sonnet-authorized resellers. (Note that the Sonnet cable supports only one HDX card.) If you need to power two or three HDX cards, you need the Avid replacement cable: ASY.CBL.POWER.MACPRO XD_CORE.TRIPLE REV.A, Part Number: 9180-60004-00.
