Introduction to the Self Study Guide

Description

The purpose of this self-study is to prepare Dell Service Providers (DSPs)

to service the Dell PowerEdge 1550. It does so in various sections. The

first section identifies the target markets and the needs of those markets.

Then it describes the features that allow the Dell PowerEdge 1550 to serve

the needs of those markets

The next section describing how the Dell PowerEdge 1550 integrates into

a rack and how to remove/replace each field replaceable unit.

This is followed by an overview of the Dell Service provider (DSP)

program, the requirements of a DSP, and how to perform DSP specific

tasks such as changing the service tag number of a system board.

The final section, Technical Appendix, contains more in depth information

about the features of the PowerEdge 1550. Familiarity with this

information will aid the technician in servicing the PowerEdge 1550.

Goals

The goal for this document is to prepare Dell Service Providers (DSPs) to

service the Dell PowerEdge 1550. Servicing the PowerEdge 1550

requires an understanding of how the components of the system

interconnect and how the user interface of the disk subsystem works.

Understanding the target market of the system and how the system can

communicate failures can also enhance service offerings. This document

provides information that will allow DSPs to understand the kind of

environment to expect when servicing the PowerEdge 1550 and to take

advantage of the features of the PowerEdge 1550 during service calls.

PowerEdge 1550 Overview

Introduction

This section provides information about the customer to which the

PowerEdge 1550 is designed to appeal. It also provides a description of

the feature set that allows the PowerEdge 1550 to serve the needs of those

customers.

The information contained in this section is helpful because it can provide

the DSP with a clear picture of the types of environments to expect when

servicing the PowerEdge 1550. It also provides the right information for a

DSP to be able to answer simple questions that the customer may have or

to understand error messages, error lights, or error codes that the system

may display.

Product Positioning

The PowerEdge 1550 is a general-purpose (GP) ultra rack-dense 1U (1.75-

inch) server targeted to support Internet and network infrastructure

applications, including gateways, DNS servers, and DHCP servers. The

PowerEdge 1550 provides unprecedented levels of performance,

availability, and scalability in a 1U form factor, including dual Pentium III

processors (up to 1 GHz), a new chipset (ServerWorks HE SL) that

supports dual 64-bit/66 MHz PCI slots on separate PCI buses for

maximum I/O throughput, up to three hot-pluggable 1-inch SCSI hard

drives, embedded Ultra3 SCSI, and up to 2 GB of RAM (4 GB when 1 GB

DIMMs become generally available on the market).

The explosive growth of the Internet has fueled the need for rack dense

servers as service providers (ISPs/ASPs), dot-coms, enterprise customers,

or any organization leveraging Internet technologies all struggle with the

same fundamental issue – data center space. Data center space is either

scarce, expensive, or both for most organizations so whether customers

build their own data centers or lease space from a service provider,

companies must maximize their return by deploying as many servers as

possible in the smallest space possible. These factors have made 1U

servers extremely attractive.

Traditionally, common product segmentation divided server products into

workgroup, departmental, and enterprise systems. This classification tied

a product’s features with its price point. With the growth of the ultra rack

dense server market, including products such as the PowerEdge 1550 and

PowerEdge 2450, a new thin server segment has emerged. While these

servers can cut across all of the traditional segments, 1U servers are

primarily deployed in the front end (first tier) of the traditional 3-tier

architecture where rack density is the most critical.

More in depth information can be found in the technical appendix at the

end of this document.

Integrated Video

The video controller used on the PowerEdge 1550 is an ATI-Rage XL

connected to the PCI bus with 4 MB of video RAM. Since the chips are

not installed in sockets and there are no empty sockets the amount of

video memory cannot be upgraded.

Version 0.3, 4 December, 2000 DCSE: PowerEdge 1550 Self-Study

Dell Page 9

troubleshooting purposes as it will work regardless of the status of the

control panel.

External - Front

• One (1) combined keyboard/mouse connector

• One (1) VGA connector.

The front of the system has three accessible ports, a combined

keyboard/mouse connector and a VGA connector. The combined

keyboard/mouse uses a Y-cable that combined the signals of a keyboard

and a mouse into one connector. The front connections become active and

disable the rear connections when a monitor is connected to the VGA

connector on the front of the system.

System LED Indicators

DCSE: PowerEdge 1550 Self-Study Version 0.3, 4 December, 2000

Page 10 Dell

Power-on LED:

• On green solid: powered and running.

• Amber blinking: sleep state.

Hard Drive LED Operation

When used in conjunction with a PowerEdge Expandable RAID

Controller, the backplane supports enhanced LED patterns to inform the

user of drive activity. The following functions (taken from Backplane

Firmware Specification) are implemented:

• IDENTIFY

The IDENTIFY condition is the highest priority condition of the indicated

conditions. This condition can apply to both populated and empty slots.

The online/fault LED is flashing green on for 125 ms, off for 125 ms and

so on.

The IDENTIFY status condition is terminated when another status

condition is set using the SAF-TE "perform slot operation" command,

when a drive is inserted into or removed from the Identified slot, or after

thirty seconds have elapsed.

• SLOT DEVICE BEING PREPARED FOR REMOVAL

This pattern is displayed during the 30-second drive spin-down period.

The online/fault LED is flashing green on for 250msec, off for 250msec

and so on.

(For all additional status conditions, the activity led is used only to

indicate drive activity.)

• SLOT DEVICE BEING PREPARED FOR OPERATION

This pattern is displayed during the 3-second drive power up period. The

online/fault LED is green on.

• SLOT EMPTY

The online/fault led and the activity led (since there is no drive present)

are off.

• SLOT READY FOR DRIVE INSERTION OR REMOVAL

The online/fault led and the activity led are all off.

• DRIVE FAILED

Version 0.3, 4 December, 2000 DCSE: PowerEdge 1550 Self-Study

Dell Page 11

The online/fault LED is amber on for 125msec, off for 125msec

• DRIVE REBUILDING

The online/fault LED is flashing green on for 500msec, off for 125msec

and so on

• DRIVE PREDICTED FAILURE

The online/fault led is green on for 500 ms, amber on for 500

milliseconds, and off for 1000ms.

• DRIVE ONLINE (No other displayable status).

The online/fault led is green on.

Chassis

The PowerEdge 1550 is a 1U system. The term "U" is a unit of measure

in rack mountable components. A U is 1.75". This unit of measure

describes the height of a product and therefore the Dell PowerEdge 1550

is 1.75 inches high.

At 1U the PowerEdge 1550 is half the height of a PowerEdge 2450. More

PowerEdge 1550 systems can fit into a rack than PowerEdge 2450

systems.

Dell Open Manage Array Manager

Dell OpenManage Array Manager is a user interface for installing and

managing RAID storage environments that are independent of an

underlying hardware RAID controller.

This gives users a consistent look and feel regardless of the actual RAID

controller being used.

Over time, Array Manager will be integrated with all of Dell storage products:

• The earliest releases focused on host-based RAID controllers only.

• Subsequent releases have added external RAID systems and validation

with Dell SAN configurations.

• Future releases will include interoperability with an integrated product

strategy for Dell SAN Management.

Array Manager hides the differences between these tools by unifying them

through a consistent look and feel. This is accomplished by providing

users with a single GUI, built on a common API through which each

vendor’s RAID or host bus adapter is accessed.

DCSE: PowerEdge 1550 Self-Study Version 0.3, 4 December, 2000

Page 12 Dell

In addition, Array Manager extends the value of the vendors’ tools by

enabling them to be run from a central console that is not necessarily co-

located with the devices being configured and managed.

More information including installation and basic usability is located in

the technical appendix at the end of this document.

Racking hardware for Dell Four Post Racks

Rails

The Dell PowerEdge 1550 uses a new rail design that does not rely on the

cage nuts for mounting the racking hardware. There are two rails and they

are not interchangeable. The proper orientation of the rail can be

determined by locating the screw holes on the rails. There is one hole in

the front and one on the side. The images that follow are close-up views

of the front the rails as if you were looking at the rails from the front. The

rail shown on the left would be on your left side looking at the front and

the rail shown on the right would be on your right side looking at the front.

The screw hole at the top of the rail shows through a square cutout in the

rack and the hooked tab hooks into another square cutout just below. The

screw hole has been circled in the preceding pictures. The tab that has the

screw hole is mounted on a pivot with a tension spring. The spring is

visible in the picture on the left. It is designed to pivot back providing

room for the bracket to be installed at an angle allowing the hook to

properly hook into the square cutout on the rack.

Version 0.3, 4 December, 2000 DCSE: PowerEdge 1550 Self-Study

Dell Page 13

The screw holes are bored into separate pieces that can pivot. The images

above show the placement of these pieces and the tension springs that

cause them to fall back into place. In these pictures the tension springs are

not flexed. The images below are of the same portion, just with the

tension springs flexed.

The rear of the rails are designed in the same manner except the top of the

rails do not have screw holes, they are just pegs that poke through the

square holes in the racks.

Cross Brace

A third piece of hardware used for placing the PowerEdge 1550 into a

rack is a cross brace that sits in the back of the rack. The brace has two

sets of interlocking pieces for its connection to the mounting rails.

DCSE: PowerEdge 1550 Self-Study Version 0.3, 4 December, 2000

Page 14 Dell

At the back of both mounting rails is a notch that the brace rests on. This

notch is indicated in the picture that follows by a red rectangle.

There is a hook on both sides of the brace that rest in the notches on the

rails. This is indicated in the following picture by the red circle.

There is also a peg on the rails that notches in the brace fits onto a notch.

The brace is indicated in the following picture by a red rectangle. The

image is a close-up from the inside of the rail.
