Reliability, availability, and serviceability
Reliability, availability, and serviceability (hereinafter referred to as RAS) are three important server design
features. The RAS features help you 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 50)
– ThinkServer Trusted Platform Module (TPM), which is a security chip, to help enhance server security
Note: The TPM is available only 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
– An intrusion switch that informs you that the server cover is not properly installed or closed by creating
an event in the system event log (SEL)
• 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 47.
– TSM (also known as BMC) and Intelligent Platform Management Interface (IPMI) 2.0
The system board platform management subsystem is based on the integrated TSM features. The
TSM is a management chip that is integrated on the system board of your server. With the TSM, 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 TSM-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 TSM, 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
TSM 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 TSM 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 TSM in the ThinkServer
System Manager User Guide, which is available for download at:

– Hot-swap feature
Your server supports hot-swap storage drives (including hard disk drives and solid-state drives) 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.
