5. 4x3.5 Hot-Swap Back Plane (HSBP)
5.1 Overview
The Chassis supports 4x3.5 SAS/SATA backplane. The backplane provides the platform
support for up to four hot-swap SAS or SATA hard drives.
5.1.1 Key Features
The 4HDD SAS/SATA HSBP supports the following feature set:
1. 4x SAS/SATA 3.5" hot swap hard drive at 6Gb SAS/SATA or slower speeds.
2. One SGPIO SFF-8485 interface from a 5pin connector.
3. One I
2
C interface from a 5pin connector for HDD status communication to BMC over slave
SMBus*.
4. Temperature sensor and FRU support.
5. In-application FW updateable over I
2
C interfaces from the BMC. No special hardware
needed for field FW upgrade with BMC onboard EPSD baseboard.
6. Four HDD status LEDs and four HDD activity LEDs.
7. Four HDDs detect inputs to the microcontroller.
8. 3.3V linear regulator for to power microcontroller and various other components.
9. Four 7 pin shrouded latching THMT SAS/SATA input connectors.
10. 29pin SAS/SATA 'hybrid' docking hot-swap connectors.
