10 About Your System
System Overview
Your system can include up to ten server modules (or blades) (see Figure 1-1). Each server module
functions as an individual server encompassing up to two microprocessors, up to two hot-pluggable hard
drives, and up to eight memory modules. 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. Server Modules
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. Table 1-1 shows the status features.

Server Module Features
Each server module has one power button and one KVM module selection button on the front (see
Figure 1-3). The indicators include a power indicator, network link indicators, and a KVM module
indicator. The server module also has a custom port on the front of the module. Use the custom cable
included with your system to connect this port to two USB devices (for example, USB diskette drive,
USB CD drive, USB mouse) and to video.
NOTE: The USB devices can only be connected by using the custom cable supplied with the system.

power button
N/A None Turns server module power off and on.
• If you turn off the module using the power button and
the module is running an ACPI-compliant operating
system, the module can perform an orderly shutdown
before the power is turned off.
• If the module is not running an ACPI-compliant
operating system, power is turned off immediately after
the power button is pressed.
• Press and hold the button to turn off the server module
immediately.
The button is enabled in the System Setup program. When
disabled, you can only use the button to turn on the server
module.

16 About Your System
Using USB Diskette or USB CD Drives
Each server module has a USB port on the front of the server module which allows you to connect a
custom cable for a diskette drive or USB CD drive. The USB drives are used to configure the server
module.
NOTICE: The system supports only Dell-branded USB 1.1 or USB 2.0 drives. The drive must be horizontal and level
to operate properly.
NOTE: If the drive must be designated as the boot drive, connect the USB drive, restart the system, then enter the
System Setup Program and set the drive as first in the boot sequence (see "Using the System Setup Program" on
page 43). The USB device will be displayed in the boot order setup screen only if it is attached to the system before
you run the System Setup program.
Hard-Drive Features
Each server module supports one or two hot-pluggable SAS hard drives, or one or two hot-pluggable
SATA hard drives. See Figure 1-4 and Table 1-3 for information on the hard-drive indicators. Different
patterns are displayed as drive events occur in the system.
NOTICE: Each server module must have a hard drive or a hard-drive blank installed in each hard-drive bay.
NOTICE: You cannot install a SAS drive and a SATA drive within a given server module (blade). However, you can
install server modules (blades) with SAS drives and server modules with SATA drives in the same server enclosure.
Network indicators Off Indicates that the server module does not have a link to the
Ethernet switch or pass-through module.
Green on Indicates that the server module has a valid link to the
network switch module.
Green blinking Indicates network activity between the server module and
the network switch module.
NOTE: External network activity is not reported by this
indicator.

Power Supply Indicator
Each hot-pluggable power supply has indicators that provide information about power status, fault, and
the presence of AC power (see Figure 1-6). Table 1-5 lists the power supply indicator codes.
NOTE: Only 2100-W power supply modules are supported on your system. The 2100-W power supply modules
require 180–240 V input from a PDU capable of providing AC current up to 29.2 A at 180 V input. If the power supply
modules are plugged into 110-V electrical outlets, the system will not power up.
Table 1-4. Back-Panel Features and Indicators
Component Indicator Description
Power supply modules Provide information about power status (see "Power Supply Indicator Codes" on
page 20).
Fan modules Provide information about status of the system fans (see "Fan Module Indicators"
on page 21).
KVM module Provides information about the KVM module (see "KVM Modules" on page 22).
DRAC/MC module Provides information about system status, system management status, and port
status (see "DRAC/MC Module" on page 26).
PowerConnect™ 5316M
Ethernet switch module
Provides information about the 10/100/1000 BASE-T network status (see
"PowerConnect 5316M Ethernet Switch Module" on page 29).
Fibre Channel pass-through
module
Provides information about the Fibre Channel network status (see "Fibre
Channel Pass-Through Module" on page 31).
Fibre Channel switch module Provides information about the Fibre Channel network status (see "Fibre
Channel Switch Module" on page 32).
Infiniband pass-through
module
Provides information about the Infiniband network status (see "Infiniband Pass-
through Module" on page 32).
Gb pass-through module Provides information about the network status (see "Gb Ethernet Pass-through
Module" on page 33).
