System Configuration
5. Plug in the power cord and boot the system.
The passwords have been cleared. Follow the instructions above to set new system
passwords.
6. Store the system in a secure location and keep the system case locked at all times to protect
against unauthorized access.
management processor (MP)
The Management Processor (MP) card contains processor and I/O hardware that act as an
autonomous embedded device for controlling the system console, reset and power management
functions. The card connectors located on the back of the system provide:
■
Serial (Remote, Console and UPS) connectors
■
VGA connector
■
LAN connector
NOTE: This section assumes that you have the MP card installed in your system. To determine if
the card is installed, look at the back panel of your system and you will see a 25-pin Serial Port if
the MP card is installed.
Two major functions of the MP card are remote and local manageability. The Management card
contains the management processor (MP), which monitors system status and can control various
aspects of the system operation, such as power, resets, software/firmware upgrades and cooling.
The MP card manageability hardware operates on standby power, independently of the on-off
state of the rest of the system.
The MP uses the following external memory: 8 MB DRAM, 8 MB Flash and 512 KB of
NVRAM. A power monitor and watchdog timer reset the processor if standby power is out of
specification or the processor is inactive for a set amount of time. The processor also uses a 25
MHz clock.
The I/O and Memory Controller chip is connected to the Management card's I/O bus interface by
rope number seven of the system bus. The Management card consists of the following
components:
■
I/O Bus Interface

VGA Controller with 16 MB of DDR SDRAM for a video buffer
