Hot-Swap Backplane

The Intel
SR2520SAXSR supports a backplane. The backplane provides the platform support for
peripheral drives and hot-swap SAS or SATA hard drives. To eliminate several cables, the
backplanes are also used as a pathway for signals from the server board to various
platform interconnects, including those for the control panel and peripheral drives. The
backplane acts as a 'pass-through' for the SAS/SATA data from the drives to the SATA
controller on the server board or a SAS/SATA controller add-in card. It provides the
physical requirements for the hot-swap capabilities.
Note: The Intel
SATA cables installed. The Intel
