Enclosure Management Controller
The backplane utilizes the features of the Vitesse* VSC410 to implement several enclosure
management functions. The chip provides in-band SAF-TE and SES management and utilizes
the four I
management functions. The chip provides in-band SAF-TE and SES management and utilizes
the four I
2
C interfaces listed below.
1. I2C bus 0 is connected to an EEPROM which stores configuration and FRU data
2. I2C bus 1 is connected to an LM75 temperature sensor
3. I2C bus 2 is connected to an IPMB bus from the server board.
4. I2C bus 3 is connected to the LSISAS1068 SAS controller.

Hard Drive Activity and Fault LEDs
The backplanes support an activity/fault LED for each of the hard drive connectors. The LED will
illuminate green for activity or amber for a drive fault. The green activity LED is driven by the
SAS/SATA hard disk drive directly. The amber fault LED is driven by the VSC410*
management controller whenever a fault condition is detected. When the drive is used in a
RAID configuration, the RAID controller will have control over the fault LED and it may exhibit
different behavior.
