– TMM (also known as BMC), and Intelligent Platform Management Interface (IPMI) 2.0
The system board platform management subsystem is based on the integrated TMM features. The
TMM is a management chip that is integrated on the system board of your server. With the TMM
chip, no matter what condition the server operating system is in and no matter if the server is on or
off, as long as the server is connected to network and an ac power source, the interaction with the
TMM-controlled servers can be achieved through system network. The user can obtain the server
hardware health information and system event log (SEL), and is able to conduct the operations
including turning on or off the server, restarting the server, and so on. This part of server management
is independent of the operating system and is called out-of-band management.
The system board platform management subsystem consists of the integrated TMM, communication
buses, sensors, Basic Input Output System (BIOS), and server management firmware. It is responsible
for error reporting, system power control, thermal monitoring, system fan control, and other
management features. The TMM provides system management and monitoring features based on the
IPMI 2.0 specification. IPMI helps lower the overall costs of server management. You can find more
information about IPMI 2.0 from the Web site of Intel. The TMM also supports some non-IPMI features,
such as the Dynamic Host Configuration Protocol (DHCP) and the Platform Environment Control
Interface (PECI), to provide more system management functions.
Refer to the Remote Management Module User Guide on the documentation DVD that comes with your
server for more information.
– Hot-swap feature
Some models support hot-swap hard disk drives or hot-swap redundant power supplies. With the
hot-swap feature, you can install, remove, or replace hard disk drives or a failing power supply without
turning off the server.
– Preboot Execution Environment (PXE)
The Intel PXE technology enables you to boot your computers, load an operating system, or deploy
executable images from a remote server by using a network interface. The operation can be done
independently of local data storage devices (such as hard disk drives) or operating systems.
– Redundant Array of Independent Disks (RAID)
Your server supports onboard SATA software RAID and advanced SATA/SAS hardware RAID
configurations if you have a required RAID card installed. For detailed information, see "Configuring
RAID" on page 64.
– Status light-emitting diodes (LEDs) and diagnostic LEDs
For more information about the LEDs for your server, refer to the related topics in "Locations" on
page 12.
– Software programs
For more information about the software programs, see "Software" on page 11.
– Wake on LAN
When the Wake on LAN feature is enabled on a computer that is connected to a local area network
(LAN), a network administrator can remotely turn on or wake up the computer from a management
console using remote network management software. Besides, many other functions, such as data
transfer and software updates, can be performed remotely without remote attendance and can be done
after normal working hours and on weekends to save time and increase productivity.
• Advanced system management features
The advanced system management features are only available when the TMM detects the presence of
a ThinkServer Management Module Premium (TMM Premium), which also is known as the integrated
keyboard, video, and mouse (iKVM) key. The TMM Premium is a remote management module. You
can purchase a TMM Premium from Lenovo and install it on the TMM Premium connector (also known
as iKVM connector) on the system board of your server to enable the iKVM function and activate the
advanced system management features.
