Chapter 3. General information

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

Introduction

The four types of replaceable components are:
• Consumables: Purchase and replacement of consumables (components, such as batteries and printer
cartridges, that have depleting life) is your responsibility. If Lenovo acquires or installs a consumable
component at your request, you will be charged for the service. For a list of consumable parts, see
http://www.lenovo.com/support.
• Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If Lenovo
installs a Tier 1 CRU at your request, you will be charged for the installation.
• Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or request Lenovo to install it, at
no additional charge, under the type of warranty service that is designated for your server.
• Field replaceable unit (FRU): FRUs must be installed only by trained service technicians.

Features and technologies

The RD220 server offers the following features and technologies:
• UEFI-compliant server firmware
UEFI replaces the basic input/output system (BIOS) and defines a standard interface between the
operating system, platform firmware, and external devices. UEFI-compliant servers are capable of
booting UEFI-compliant operating systems, BIOS-based operating systems, and BIOS-based adapters
as well as UEFI-compliant adapters.
Note: This server does not support DOS.
• Integrated Management Module
The Integrated Management Module (IMM) combines service processor functions, video controller, and
(when IMM Premium is installed) 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. IMM Premium 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
IMM Premium is required to enable the remote presence and blue-screen capture features. The remote
presence feature provides the following functions:
– Remotely viewing video with graphics resolutions up to 1280 x 1024 at 75 Hz, regardless of the system
state
– Remotely accessing the server, using the keyboard and mouse from a remote client
