Ethernet connectivity
The server comes with an integrated Intel Gigabit Ethernet controller as well as an Ethernet physical layer
(PHY) of the Open Systems Interconnection model (OSI model). They provide the server with the ability
to support two Ethernet connectors on the rear panel with 10 Mbps, 100 Mbps, or 1000 Mbps network
connectivity. For more information, see "Rear view of the server" on page 19.
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
– Server locks (see "Server locks" on page 22)
– Administrator password and user password to help protect unauthorized access to the server (see
"Using passwords" on page 65)
– Trusted Platform Module (TPM) connector on the system board for a TPM module, which is a security
chip, to help protect your server and enhance server security
Note: The TPM module is only available in some models.
– Remote monitoring or control by an administrator to provide protection or help
– Hot-swap redundant power supply modules to help you avoid significant interruption to the operation
of the system when a power supply module fails (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 55.
– 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
the 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, Basic Input Output System (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.
Refer to the Remote Management Module User Guide on the documentation DVD that comes with your
server for more information.
