Introduction
The four types of replaceable components are:
v 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.
v 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.
v 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.
v 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:
v 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.
v 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
v Remote presence capability and blue-screen capture
