4.3.1.4 Monitoring Module
The monitoring module (IPMC) is a component of the equipment monitoring system. It
forms intelligent platform management system together with hardware management bus
and software monitoring management module. IPMC is designed as modular subcard
and located at the main control board and other boards. The monitoring modules of the
main control board and other boards are interconnected via monitoring bus.
IPMC module can be divided to IPMC management node and IPMC ordinary node by its
role in the system. IPMC in the active main control board is the manager of subsystems;
the standby main control board and ordinary line cards are all IPMC ordinary nodes. The
line card and standby main control functional nodes collect local information and send it
to the active main control node to provide for the users. The control information sent by
the users is distributed by the active main control node to the line card and standby main
control functional nodes. The management node also monitors system power supply and
fans.
The monitoring module fulfills the following tasks:

Information collection: collect information on environment temperature, board
temperature, fan status, power supply statue and power supply power sampling;

Monitoring alarm: set alarm parameters for the above detection items and generate
corresponding alarms when relevant faults occur;

Monitoring management: realize fan rotational speed control by user or automatic
control as well as board power-on and power-off functions.
