2.6.2
IPMI Implementation on the CP605
On the CP605, the IPMI functionality is realized using the ZIRCON-Lite controller from QLogic,
which is an ARM7TDMI core-based IPMI controller. Due to the fact that this controller can act
as BMC and as PM on all versions of the CP605, the same controller can be used. All the in-
formation collected by the ZIRCON-Lite is then accessible by software through a key-
board-style Interface (see IPMI-Intelligent Platform Management Interface Specification V.1.0
for more information) whose address space is available in the I/O space of the Intel CPU’s ad-
dress map, or via the IPMB-Bus.
2.6.3
Measurement of Onboard Voltages
On the CP605 all voltages are monitored by the ZIRCON-Lite. This means 5V, 3.3V, 2.5V,
VCORE, VIO, 12V and -12V.
2.6.4
Measurement of Temperatures
An onboard sensor measures the temperature in the vicinity of the CPU (positioned below the
heat sink).
2.6.5
Fan Control
Four Tacho inputs and two PWM outputs are routed to the rear I/O connector. These make it
possible to control the fan speed to regulate system cooling.
2.6.6
Data Repositories
All the data gathered by the BMC is stored in a non-volatile memory providing the possibility to
obtain information about working conditions and failure situations.
