Intel S7000FC4UR Technical Product Specification

HSC Functional Specifications Intel® Server System S7000FC4UR
Revision 1.0
Intel order number E18291-001

29.2.2 Sensor Initialization
The HSC receives sensor initialization values from the baseboard management controller
(BMC). The BMC sends IPMI sensor initialization values to the HSC during IPMI initialization
agent runtime.
29.2.3 Cable Detection
The HSC detects the presence of the SFF-8087 cables upon firmware initialization. The
detection is done via active-low GPIO signals routed from out-of-band signal ground pins. Each
SFF-8087 connection corresponds to four disk drive connections. Depending on the
combination of presence signals, the HSC configures itself for four- or eight-disk management
as shown in Table 108. After self-configuration, the HSC only acknowledges either four or eight
disks in management responses. In a four disk configuration (cable A only) the HSC reports four
disk slots in IPMI, SAFTE, and SES responses. All LEDs remain accessible via IPMI and
SGPIO, regardless of the number of cables detected.
Table 108. Cable Detect Configuration
Cable A Detected Cable B Detected Configuration
No No Invalid Configuration: will use 8 disks by default.
No Yes Invalid configuration: will use 8 disks by default.
Yes No Will use 4 disks.
Yes Yes Will use 8 disks.
29.3 System Event Log (SEL)
The VSC410 controller does not implement a system event log. Instead, SEL entries are
maintained by the BMC. If the BMC is unable to accept platform event messages, the VSC410
does not cache the entries.
29.4 Sensor Data Repository (SDR)
The VSC410 controller does not implement a sensor data repository. Instead, the BMC
maintains the HSC SDR entries.
29.5 Field Replaceable Unit (FRU) Inventory Device
The VSC410 supports an I
2
C-compatible EEPROM for FRU storage located at address
0xAC.The EEPROM is on a private I
2
C bus, and is accessible only by the HSC, or through
Master write-read I
2
C commands.
The FRU storage contains:
 Common header
 Internal use area
 Board information area
