• Security features
– Administrator password and user password to help you protect unauthorized access to the server
(see "Using passwords" on page 69)
– Hot-swap redundant power supplies to protect against significant interruption to the operation of the
system when a power supply fails (for server models that come with one power supply, you can
purchase a hot-swap redundant power supply option from Lenovo and install it into your server as the
second power supply for redundancy)
– Redundant Array of Independent Disks (RAID) configuration for improving data storage reliability and
fault tolerance (see "Configuring RAID" on page 76)
– Remote monitoring or control by an administrator to provide protection or help
– ThinkServer Trusted Platform Module (TPM), which is a security chip, to help enhance server security
Note: The TPM is only available in some models.
• Basic system management features
– Ability to store the power-on self-test (POST) hardware test results
– BIOS Setup Utility program
The BIOS Setup Utility program helps you view the server information and configure the server in the
pre-operating system environment. See "Using the Setup Utility program" on page 65.
– 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, 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.
You can find the default user name, password, and other information for the TMM in the ThinkServer
Management Module User Guide, which is available for download at:

– 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 start 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.
– RAID
