Video subsystem
An integrated graphics controller in the ThinkServer Management Module (TMM), which also is known
as the Baseboard Management Controller (BMC) chip, on the system board to support VGA connectors
for connecting video devices
Ethernet connectivity
Three RJ-45 Ethernet connectors on the rear panel with 10 megabits per second (Mbps), 100 Mbps, or
1000 Mbps network connectivity.
• Onboard Intel 82574 Gigabit Ethernet controller for dedicated or shared local area network (LAN)
management interface (Ethernet connector 0 is for system management)
• Onboard Intel Gigabit Dual Port Ethernet controller for Ethernet connector 1 and Ethernet connector 2

Reliability, availability, and serviceability
Reliability, availability, and serviceability (hereinafter referred to as RAS) are three important server design
features. The RAS features help you to ensure the integrity of the data stored on the server, the availability of
the server when you need it, and the ease with which you can diagnose and correct problems.
Your server has the following RAS features:
• Security features
– Administrator password and user password to help protect unauthorized access to the server (see
"Using passwords" on page 49)
– ThinkServer Trusted Platform Module (TPM), which is a security chip, to help enhance server security
Note: The TPM is only available in some models.
– Remote monitoring or control by an administrator to provide protection or help
– Hot-swap redundant power supplies to help avoid significant interruption to the operation of the
system when a power supply fails
• 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 45.
– 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, 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
