Power System Management Bus (I
2
connector (JPI C1) monitors power
supply, fan and system temperatures.
See the table on the right for pin
defi nitions.
IPMB
A System Management Bus header for
IPMI 2.0 is located at JIPMB1. Connect
the appropriate cable here to use the
IPMB I 2 C connection on your system.
Fan Headers
This serverboard has six system/CPU
fan headers (Fan 1-Fan 4, Fan A and
Fan B ) on the serverboard. All these
4-pin fans headers are backward
compatible with the traditional 3-pin
fans. However, fan speed control is
available for 4-pin fans only. The fan
speeds are controlled by Thermal
Management via IPMI 2.0 interface.
See the table on the right for pin
defi nitions.
S-SGPIO and I-SGPIO 1/2 Headers
Three SGPIO (Serial Link General
Purpose Input/Output) headers are
located on the serverboard. I-SGPIO
1 supports I-SATA 0-3, and I-SGPIO 2
supports I-SATA 4/5. S-SGPIO is used
for S-SATA 0-3. See the table on the
