Hot-Swap Back Plane (HSBP) Intel® Server Chassis P4000M Family TPS 5. Hot-Swap Back Plane (HSBP) 5.1 4U 4x3.5" Hot-Swap Back Plane (HSBP) 5.1.1 Overview The Chassis supports 4x3.5" SAS/SATA backplane. The backplane provide the platform support for up to four hot-swap SAS or SATA hard drives. 5.1.1.1 Key Features The 4HDD 3.5" SAS/SATA HSBP supports the following feature set:  4x SAS/SATA 3.5" hot swap hard drives.  One SGPIO SFF-8485 interface from a 5pin connector. This 5pin connector will be common with all other HSBPs  One I2C interface from a 5pin connector for HDD status communication to BMC over slave SMB bus.  Temperature sensor and FRU support  In-application FW updateable over I2C interface by BMC. No special hardware needed for field FW upgrade with BMC onboard EPSD baseboard  4 HDD status LEDs and 4 HDD activity LEDs  4 HDD presence detect inputs to the microcontroller  3.3V linear regulator for to power microcontroller and various other components  Four 7pin shrouded latching THMT SAS/SATA input connectors  29pin SAS/SATA 'hybrid' docking hot-swap connectors  Mount board using one loose screw 5.1.1.2 Board Layout The following figure shows the board layout and connectors placement of the 4HDD SAS/SATA hot-swap backplane: 104 Intel order number G27488-004 Revision 1.1
