Figure 25. SAS 6Gbs Bridge Board Overview
This bridge board passes all electrical connectivity through a 2x40pin card edge hot swap
interconnect between compute node/SAS RAID card and chassis backplane. The bridge board
passes the follow features (per compute node) to the backplane of the server:
 4x 6Gb SAS/SATA signals through Mini SAS port to HSBP drives.
 Two x4 lane 6Gb SAS/SATA re-drivers.
 Four chassis ID signals to determine the physical location of the compute node.
 One SGPIO SFF-8485 interface to the HSBP microcontroller.
 5V_AUX power generated on HSBP and provided to the compute node.
 3.3V power generated on HSBP and provided to bridge board to run SAS/SATA re-
drivers.
 Global PMBus* alert signal for CLST support.
 Four SMBus* interfaces:
o SMBUS R1 - For chassis temp sensor and chassis FRU EEPROM device.
o SMBUS R5 - Connectivity for up to two HSBP controllers and one shared 12V
current monitoring device.
o SMBUS R7 - Connectivity to up to two common redundant power supply (CRPS)
module PMBus*.
o IPMB - For OEM requirement not used on EPSD HW servers.
o Front panel button signals: Power, reset, NMI, and ID.
o Front panel LEDs signals: Power, fault, status, fabric activity, ID, HDD activity.
