Service Features Technical Specifications

Overview

Your network attached storage (NAS) appliance enables you to easily add storage to a workgroup, small office,

or small business network and offload the file management responsibilities from the server. The NAS appliance

is a "headless" device, which means it has no keyboard, mouse, or monitor, but can be managed through the

network or by using console redirection through a serial connection. The system offers the data security

capabilities of general-purpose servers.

This document provides basic information about the system features, service features, and specifications.

System Features

The system offers the following major features:

An Intel® Celeron™microprocessor with an internal bus speed of at least 850 MHz or an Intel Pentium® III

microprocessor with an internal bus speed of at least 1 GHz

1-U chassis

Two DIMM slots

Four IDE hard drives connected to four IDE master channels in a software RAID configuration

162-W power supply

System cooling fan and two power-supply cooling fans

Serial port used for console redirection

One 32-bit, 33-MHz low-profile PCI slot

A minimum of 256 MB (for early systems with a SN1A system board) or 384 MB (for later systems with a SN1B

system board) of SDRAM system memory, upgradable by installing registered PC-133 SDRAM memory modules in

the two memory module sockets

A flash BIOS that can be upgraded through console redirection

Two integrated Intel 82559 10/100+ NICs with RJ-45 Ethernet connectors

The following software is included in the system:

Microsoft® Windows® Powered operating system with Service Pack 2.

Microsoft Server Appliance (SA) kit.

Services for UNIX®, Novell® NetWare®, and Macintosh (integrated into the Microsoft Windows Powered operating

system).

Protocol support for TCP/IP, DHCP (client support), DNS (client support), NIS (client support), IPX, CIFS, NFS, and

IPV6.

First Time Configuration support through DHCP, Dell OpenManage™ Kick-Start, or RAS serial connection (setup

through serial connection in non-DHCP environments).

Disk management through Dell OpenManage Array Manager.

Dell ActiveArchive™ snapshot software.

A BIOS Setup utility for quickly viewing and changing the system configuration information.

Diagnostics for evaluating your system's components and devices. For more information about using the system

diagnostics, see your Installation and Troubleshooting Guide.

Service Features

The system includes the following service features to make troubleshooting and repair easy and effective, in most cases

without tools or service aids:

A temperature monitor that shuts down the system if the temperature exceeds the threshold setting.

System diagnostics, which checks for hardware problems.

PowerVault NAS Manager, which is used through a browser to monitor and manage the system.

A chassis and system board that simplifies removing and replacing components.

Microsoft Windows powered operating system online help (available through Terminal Services).

The system chassis simplifies removing and replacing system components. You can replace an expansion card, a

microprocessor, or DIMMs without removing the system board. The midplane board and hard- drive carriers eliminate the

extensive cabling and drive configuration usually required for a hard- drive subsystem.

Power Protection Devices

Devices are available that protect against power problems such as power surges, transients, and power failures. The

following subsections describe some of the 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 voltage spikes, such as those caused during an electrical storm, from entering a

system through the electrical outlet. Surge protectors, however, 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, therefore, can handle brownouts. Because of this added protection, line

conditioners cost more than surge protectors—up to several hundred dollars. However, the 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 lost. The battery is charged by the AC power while it is available, so 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 allow you to conduct an orderly shutdown of the system, but they are not intended to provide

continued operation. Surge protectors should be used with all UPS systems, and the UPS system should be Underwriters

Laboratories (UL) safety-approved.

Overview Internal Visual Inspection

Initial User Contact Running System Diagnostics

External Visual Inspection Obtaining Technical Assistance

Observing the Boot Routine

Overview

This section describes basic troubleshooting procedures that can help you diagnose a system problem. The procedures can

often reveal the source of a problem or indicate the correct starting point for servicing the system. See your Installation

and Troubleshooting Guide for more detailed instructions on troubleshooting your system.

A brief explanation of how to load and start the system diagnostics can be found in "Running System Diagnostics."

NOTE: To perform troubleshooting, you can use the console redirection function on the serial port (COM1). See the

System Administrator's Guide for more information about console redirection.

Perform the following procedures in the order presented.

Initial User Contact

When you first contact a user who has a problem, ask the user to describe the problem and the conditions under which it

occurs. After the user describes the problem, perform the following steps:

1. Ask the user to back up any data on the hard drive if the system’s condition permits.

See the documentation provided with the operating system or applications software for information about backing

up data.

2. Ask the user to duplicate the problem by repeating the operations he or she was performing at the time the

problem occurred.

Can the user duplicate the problem?

Yes. Proceed to step 3.

No. Proceed to the next section, "External Visual Inspection."

3. Observe the user to determine if he or she is making an error, such as typing an incorrect key combination or

entering a command incorrectly.

Is the problem a result of user error?

Yes. Instruct the user in the proper procedure or direct the user to the appropriate user documentation for the

correct procedure.

No. Proceed to "External Visual Inspection."

External Visual Inspection

Improperly set switches, controls, and loose or improperly connected cables are the most likely source of problems for the

system or other peripherals. A quick check of all the switches, controls, and cable connections can easily solve the

problems.

The external visual inspection consists of a quick inspection of the exterior of the system and cables. While performing the

visual inspection, make any necessary corrections. To perform the external visual inspection, perform the following steps:

1. Inspect the system status LEDs for an indication of component malfunction.

2. Turn off the system, including any attached peripherals.

3. If the system is connected to a power distribution unit (PDU), turn the PDU off and then on again.

If the system is not receiving power, plug the PDU into another electrical outlet. If it still is not receiving power, try

another PDU, and then reconnect the system to the electrical outlet or PDU.

4. Inspect the exterior of the system, including all controls and indicators, and all user-accessible data storage devices

for any signs of physical damage.

Does the inspection reveal any problems?

Yes. Proceed to the appropriate procedure in "Removing and Replacing Parts."

sound when you access a hard drive See "Hard Drives" in "Removing and Replacing Parts."

Internal Visual Inspection

NOTICE: Before you proceed with the internal visual inspection described in this section, ensure that the user has

saved all open files and exited all open application programs, if possible, to prevent loss of data.

A simple visual inspection of a system’s interior hardware can often lead to the source of a problem, such as a loose

expansion card, cable connector, or mounting screw. When you perform the visual inspection, see "System Features" to

locate components referenced in the inspection procedure.

To perform the internal visual inspection, perform the following steps:

1. Turn off the system, including any attached peripherals, and disconnect all the power cables from electrical outlets.

CAUTION: Before beginning to work inside the system, disconnect the power supply from the power

source and the power supply cables from the power supply.

2. Remove the system cover as described in "System Cover."

CAUTION: The microprocessor and heat-sink assembly can get extremely hot during system operations.

Be sure that it has had sufficient time to cool before touching it.

CAUTION: When handling the microprocessor and heat-sink assembly, take care to avoid sharp edges

on the heat sink.

3. Verify that the memory modules, expansion cards, and microprocessor and heat-sink assembly or assemblies are

fully seated in their sockets or connectors.

4. To remove and reseat a microprocessor and heat-sink assembly, perform the steps described in "Microprocessor."

5. To remove and reseat a memory module, perform the steps described in "Memory Modules."

6. If you need to remove and reseat an expansion card, remove the card as described in "Expansion Card," and

carefully reinsert the card in its connector until fully seated.

7. Verify that all jumpers are set correctly.

For information about jumper settings, see "System Board Jumpers."

8. Ensure that all cable connectors inside the system are firmly attached to their appropriate connectors.

9. Replace the system cover.

10. Reconnect the system and any attached peripherals to their power sources, and turn them on.

Does the problem appear to be resolved?

Yes. No further steps are necessary.

No. Proceed to "Obtaining Technical Assistance."

Running System Diagnostics

NOTE: To run the system diagnostics, you must use the console redirection function on the serial port (COM1). See

the System Administrator's Guide for more information about console redirection.
