System Configuration
iLO MP Card I/O
The iLO MP card contains a processor and I/O hardware that act as an autonomous embedded
device for controlling the server console, reset, and power management functions.
NOTE: This section assumes that the iLO MP card is installed in the server. To determine if the
card is installed, look at the back panel of the server. You will see a 25-pin serial console port if
the iLO MP card is installed.
Two major functions of the iLO MP card are remote and local manageability. The iLO MP card
contains the management processor which monitors server status and can control various aspects
of the server operation, such as power, resets, software/firmware upgrades, and cooling. The iLO
MP card manageability hardware operates on standby power, independently of the on-off state of
the rest of the server.
The iLO 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 iLO MP card’s I/O bus interface by rope
number seven of the system bus. The iLO MP card consists of the following components:
■ I/O bus interface
■ VGA controller with 16 MB of DDR SDRAM for a video buffer
■ MP with:
❏ Three RS-232 serial console ports
❏ Four I
2
C ports
❏ 10/100 BT LAN
❏ 16-bit GPIO interface
■ Management Processor DRAM, flash memory and battery backed NVSRAM
■ I

C battery backed real time clock
■ I

C field replaceable unit EEPROM
■ I

C 8K serial EEPROM
■ System reset logic
The iLO MP card includes these I/O components:
■ System serial console ports:
❏ Three RS-232 serial console ports can be accessed through one three-connector cable
(A6144-63001, dongle) when this cable is connected to the DB25 connector located on
the backplane of the server. This cable provides for three DB9 connectors for console,
modem and UPS.
❏ The iLO MP card serial ports can be configured to redirect server console and session
communications to the RS-232 lines (local port) and a modem (remote port).
■ VGA controller. The 2D VGA graphics controller console port is provided on a DB15F
connector. Also, Serial Flash memory with VGA BIOS and a 16 MB video buffer (DDR
SDRAM) is included with the VGA controller.
