Chapter 3. General information

This chapter provides general information that applies to all machine types supported by this publication.

Features and technologies

The server uses the following features and technologies:
• UEFI-compliant server firmware
The UEFI-compliant server firmware offers several features, including Unified Extensible Firmware
Interface (UEFI) version 2.1 compliance, Active Energy Management (AEM) technology, enhanced
reliability, availability, and serviceability (RAS) capabilities, and basic input/output system (BIOS)
compatibility support. UEFI replaces the legacy BIOS. UEFI defines a standard interface between the
operating system, platform firmware and external devices, and offers capabilities that far exceeds that of
the legacy BIOS.
The server design combines the UEFI capabilities and features with legacy BIOS compatibility. The
server is capable of booting UEFI-compliant operating systems, BIOS-based operating systems, and
BIOS-based adapters as well as UEFI-compliant adapters.
Note: The server does not support Disk Operating System (DOS).
• Integrated Management Module
The integrated management module (IMM) combines service processor functions, video controller,
and remote presence function in a single chip. The IMM provides advanced service-processor control,
monitoring, and alerting function. If an environmental condition exceeds a threshold or if a system
component fails, the IMM lights LEDs to help you diagnose the problem, records the error in the event
log, and alerts you to the problem. The IMM also provides a virtual presence capability for remote server
management capabilities. The IMM provides remote server management through industry-standard
interfaces:
– Intelligent Platform Management Interface (IPMI) version 2.0
– Simple Network Management Protocol (SNMP) version 3
– Common Information Model (CIM)
– Web browser
• Remote presence capability and blue-screen capture
The remote presence feature provides the following functions:
– Remotely viewing video with graphics resolutions up to 1600 x 1200 at 85 Hz, regardless of the system
state
– Remotely accessing the server, using the keyboard and mouse from a remote client
– Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO
and diskette image files as virtual drives that are available for use by the server
– Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive
The blue-screen capture feature captures the video display contents before the IMM restarts the server
when the IMM detects an operating-system hang condition. A system administrator can use the
blue-screen capture to assist in determining the cause of the hang condition.
• Preboot diagnostics program
The preboot diagnostics programs are stored on the integrated USB memory. They collect and analyze
system information to aid in diagnosing server problems. The diagnostic programs collect the following
information about the server:
