– 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, 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, locking the power switch on the front panel, 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, the 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.

– Hot-swap feature
Your server supports hot-swap hard disk drives, hot-swap system fans, and hot-swap redundant
power supplies. With the hot-swap feature, you can install, remove, or replace a hot-swap device
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 advanced SATA/SAS hardware RAID if your server has a required RAID card
installed. For detailed information, see "Configuring RAID" on page 66.
– 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 14.
– Software programs
For more information about the software programs, see "Software" on page 12.
– Wake on LAN
When the Wake on LAN feature is enabled on a computer that is connected to a 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 TMM firmware supports the following advanced system management features.
Note: 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 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
