Applications, operating systems, and the system itself are capable of identifying problems and alerting you to them. When a problem occurs, a message may
appear on the monitor or a beep code may sound.

A variety of messages can indicate when the system is not operating properly:

Server module messages

Dell™ Remote Access Card/Modular Chassis (DRAC/MC) module messages

Server module beep codes

Warning messages

Diagnostics messages

Alert messages

The system indicators and the front- and back-panel features are illustrated in this section. This section also describes each type of message and lists the
possible causes and actions you can take to resolve any problems indicated by a message.

System Overview

Your system can include up to ten server modules (or blades). Each server module functions as an individual server encompassing up to two microprocessors,
up to two hot-pluggable hard drives, and up to six memory modules (see

Figure 2

-1

). To function as a system, a server module is inserted into a chassis that

supports power supplies, fan modules, a management module (Dell Remote Access Controller/Modular Chassis [DRAC/MC]), a KVM switch module, and at least
one I/O module for network connectivity. The power supplies, fans, DRAC/MC, and I/O modules are shared resources of the server modules in the chassis. In
addition, your system may also ship with an optional external USB diskette drive and an optional external USB CD drive, which you can use to set up and
configure the server modules.

Figure 2-1. System Overview

This section describes the major hardware and software features of your system and provides information about the indicators on the system's front and back
panels. It also provides information about other documents you may need when setting up your system and how to obtain technical assistance.

NOTE:

To ensure proper operation and cooling, all bays must be populated at all times with either a server module or with a blank.
