Dell PowerEdge 4600 - Manual (Page 18)

l Two integrated NICs (one 10/100 and one 10/100/1000), which provide an Ethernet interface.
l Server management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The server management
circuitry works in conjunction with the server agent.
Systems include an IDE CD-ROM drive and a diskette drive installed in the externally accessible bays.
The following software is included with your system:
l A System Setup program for quickly viewing and changing the system configuration information for your system. For more information on this program,
see "
Using the System Setup Program ."
l Enhanced security features, including a system password and a setup password, available through the System Setup program.
l System diagnostics for evaluating your system's components and devices. For information on using the system diagnostics, see "Running the System
Diagnostics" in your Installation and Troubleshooting Guide.
Supported Operating Systems
Dell supports the following operating systems for use on your system:
l Microsoft® Windows NT® 4.0 Server
l Microsoft Windows® 2000 Server and Advanced Server
l Red Hat Linux 7.x
l Novell® NetWare® version 5.x
Power Protection Devices
A number of devices are available to protect your system from the effects of power problems such as power surges, transients, and power failures. The
following subsections describe some of these devices.
Surge Protectors
Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors
prevent overvoltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors
do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.
Line Conditioners
Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system's AC power source voltage at a fairly constant
level and provide protection from brownouts of short duration. Because of this added protection, line conditioners cost more than surge protectors—up to
several hundred dollars. However, these devices cannot protect against a complete loss of power.
Uninterruptible Power Supplies
UPS systems offer the most complete protection against variations in power because they use battery power to keep the system running when AC power is
unavailable or unusable. The battery is charged by the AC power while it is available so that once AC power is lost, the battery can provide power to the
system for a limited amount of time—from 15 minutes to an hour or so—depending on the UPS system.
UPS systems range in price from a few hundred dollars to several thousand dollars, with the more expensive units allowing you to run larger systems for a
longer period of time when AC power is lost. UPS systems that provide only 5 minutes of battery power let you conduct an orderly shutdown of the system but
are not intended to provide continued operation. Surge protectors should be used with all UPS systems, and the UPS system should be UL safety approved.
Integrated AC Transfer Switch
The integrated AC transfer switch provides redundant power. Two AC inputs are available to the switch. One of the inputs is designated as primary and is
used for powering the system. The system can operate from either input and will automatically switch from an AC input that fails to the other AC input. This
feature allows a system administrator to assign a system to a selected power circuit in multi-circuit data centers.
