2.5.4.3 Cooling
Summary
The four-fan cooling subsystem is sized to provide cooling for:
•
One Intel
®
Pentium
®
4 Processor (3.0 GHz frequency, 1 M L2 cache, 800 MHz FSB,
90nm manufacturing technology)
•
The SE7210TP1-E System Baseboard components
•
4 GB of SDRAM memory
•
Two 15,000 RPM hard drives at a maximum of 18 watts per drive
•
1 PCI card at a maximum of 25 watts
The cooling subsystem is designed to meet acoustic and thermal requirements at the lower fan
speed settings. At the higher fan speed settings, thermal requirements are met for the
maximum ambient temperatures, but acoustic requirements are not met. The environmental
specifications are summarized in 2.7.1.
2.6 Server
Management
The Telco SE7210TP1-E Server Baseboard server management architecture features the
National Semiconductor* PC87431M Baseboard Management Controller (mBMC), which
autonomously monitors server status and provides the interface to server management control
functions. This controller is responsible for controlling system power, resets, monitoring
voltages, temperatures, fans, and communicating with secondary controllers on its Intelligent
Platform Management Bus (IPMB).
The functions of the mBMC controller are summarized in the following section. The firmware for
the National Semiconductor* PC87431M* (mBMC) is not intended to be field upgraded. Refer
to the
System Server Management External Architecture Specification
for more details.
2.6.1
Baseboard Management Controller
The mBMC on the SE7210TP1-E System Baseboard provides server management monitoring
capabilities. A flash memory is associated with the mBMC that holds the operational code,
sensor data records (SDR), and system event log (SEL). There is also a serial Electrical
Erasable Programmable Read Only Memory (EEPROM) that holds the mBMC configuration
defaults and field replaceable unit (FRU) information. The various server management
functions provided by the Bus Management Controller (BMC) are listed as follows:
•
Baseboard voltage monitoring
•
Fan failure detection
•
Fan speed control
•
Processor voltage monitoring
•
Processor presence detection
•
Processor internal error (IERR) monitoring
•
Fault resilient booting (FRB)
•
Watchdog timer
•
Periodic system management interrupt (SMI) timer
•
One I

C management bus interface for communicating with SIO and ADT7463
•
System event log (SEL) management and access
