    SC846X Chassis Manual Components Drives The chassis supports twenty-four hot-swap 3.5" SAS or SATA hard disk drives in the front. The drives are supported by a backplane. In addition, you have the option to add up to six drives at the rear of the chassis.

  • Page 11: Where To Get Replacement Components

    For faster service, RMA authorizations may be requested online (http://www. supermicro.com/support/rma/). Whenever possible, repack the chassis in the original Supermicro carton, using the original packaging material. If these are no longer available, be sure to pack the chassis securely, using packaging material to surround the chassis so that it does not shift within the carton and become damaged during shipping.
