Obtaining Technical Assistance
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 1-1). 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.
NOTE:
To ensure proper operation and cooling, all bays must be populated at all times with either a server module or with a blank.
Figure 1-1. 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.
System Status Features
The chassis has front-panel control features including power and identification buttons and indicators (see Figure 1-2). Press the power button to turn on the
system; press and hold the power button to turn off the system. Pressing the identification button activates the identification indicator on both the front and
back (on the KVM module) of the system.
