Lenovo RD540 manual Video subsystem, Ethernet connectivity, Security features

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

There are three RJ-45 Ethernet connectors on the rear panel with 10 megabits per second (Mbps), 100 Mbps, or 1000 Mbps network connectivity. The Ethernet connector 0 is for system management by default. However, you also can set the Ethernet connector 1 or 2 for system management use in the Setup Utility program. See “Setting the mode of the Ethernet connectors” on page 57.

For more information, see “Rear view of the server” on page 22.

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 55)

–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 51.

–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, 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
