Server Management Interface - Intel S7000FC4UR Technical Product Specification

Intel® Server System S7000FC4UR TPS
7.3.9

Server Management Interface

The SAS backplane will support the following server management features:
Two SGPIO Interfaces
Hot-swap controller (HSC) Secure Digital Input/Output (SDIO) Interface
UART Serial Interface

7.3.9.1 Two SGPIO Interfaces
There are two SGPIO interfaces for cable A (drives 0-3) and cable B (drives 4-7). The interfaces
communicate the fault LED and present information.
7.3.9.2 HSC SDIO Interface
This interface communicates with the M25P80 flash module to access the board firmware.
7.3.9.3 UART Serial Interface
There is one serial port interface.
7.3.9.4 Local I

The local I C* interface is as follows:
SAS backplane FRU
SAS backplane temperature sensor
One temperature sensor is attached to the local I
Micro-controller interface
7.3.9.5 Local I

2
The bus A local I C* bus connects the DS75* thermal sensor and Atmel* AT24C64N (or
equivalent) serial EEPROM (with FRU data) to the Vitesse* VSC410
7.3.9.6 Isolated Global I
2
The global I C* bus connects the on-board SAS expanders to the system. The IPMB bus also
goes thru the front panel control connector for use with a liquid crystal display (LCD).
7.3.9.7 I C* I/O Bus
2
The SMB_SYS_PWR_SCL/SDA bus connects the system server management controller to the
PCA9554* device used for fan sensing and LED control. The bus address is listed in Table 17.
