Access the iBMC in NC-SI mode through the service network port of the NIC that
supports NC-SI.
The out-of-band management network cables are connected to a server node
(the default configuration on the BIOS menu). For details, see
Figure 3-4 Point-to-point cabling

In NC-SI mode, the management network cable can be used as a service network cable
and connected to a service network port.
The server node iBMC determines a proper speed based on speed adjustment
algorithms and delivers the speed to the fan management board in the middle
module to control the fan speed. The fan management board detects the
operating status of the fan modules through the rotation speed feedback signals,
and reports to server node iBMCs for the fan module health management.
The fan management board of the middle module provides four independent
pulse-width modulation (PWM) control signals for controlling the fan speed and
eight TACH signals for detecting the fan speed.
Each server node provides an I
server node supports input power queries, installation status detection, and PSU
alarm reporting.
The iBMC of each server node and the CPLD of the fan management board in
the middle module provide the GPIO to detect the presence and PWROK of
PSUs.
