xxvii Sun Enterprise 250 Server Owner’s Guide ♦ Revision A, June 1998

Preface

Sun Enterprise 250 Server Owner’s Guide answers your questions about setting up and running the Sun Enterprise 250 server. Features and options, installation, troubleshooting, parts replacement, and network administration information for the Enterprise 250 server are covered in this manual.

This manual presents information in a modular format designed to answer the type of questions that you might ask while installing, conﬁguring, and using the Enterprise 250 server. Look at the titles of the modules and you’ll ﬁnd the cue words that direct you to the categories of questions and answers, such as:

How to . . . How do I do something?

About ...Isthere more information about this topic?

Reference for . . . Where can I ﬁnd reference material for something? You determine how much or how little of the information you need to read. Using the table of contents or the task list on the ﬁrst page of each chapter, you can

quickly ﬁnd a speciﬁc topic or task. The information modules are brief; however, they are interrelated and refer to other modules that you may want to read. For instance, if you’re installing a memory module and you’re already familiar with the task, you could go to “How to Install a Memory Module” and follow the installation procedure. But if you need more background information before performing the task, you should ﬁrst read “About Memory.”

Using UNIX Commands

This document may not contain information on basic UNIX®commands and procedures such as shutting down the system, booting the system, and conﬁguring devices.

CHAPTER 1

System Overview

This chapter introduces you to the Sun Enterprise 250 server and explains some of its features. Information covered in this chapter includes:

“About the Sun Enterprise 250 Server” on page 1

“Locating Front Panel Features” on page 3

“Locating Rear Panel Features” on page 5

“About the Status and Control Panel” on page 6

About the Sun Enterprise 250 Server

The Sun Enterprise 250 server is a high-performance, shared memory, symmetric-multiprocessing server system. It is designed around Sun’s high-speed Ultra Port Architecture (UPA) cross-bar system interconnect and Sun’s UltraSPARC

The system is housed in a roll-around tower enclosure, which measures 20.4 inches high, 10.3 inches wide, and 27.1 inches deep (51.7 cm x 26.2 cm x 68.8 cm). The system has a maximum weight of 118 lb (53 kg).

Processing power is provided by up to two modular UltraSPARC II CPUs, each of which comes with 1 Mbyte or 2 Mbytes of local high-speed external cache memory. The system UPA’s clock rate synchronizes automatically to the clock rate of the installed CPUs, and the UPA bus operates at a clock rate that is one third or one fourth that of the CPU modules. For more information about CPU modules, see “About CPU Modules” on page 78.

System main memory is provided by up to sixteen memory DIMM modules, each of which is capable of storing 32, 64, or 128 Mbytes of data. Total main memory is

II processors to deliver outstanding overall system performance.

expandable up to 2 gigabytes. To enhance memory I/O performance, the system transfers 64 bytes of data into or from memory on each memory transfer. For more information about system memory, see “About Memory” on page 76.

System I/O is handled by two separate Peripheral Component Interconnect (PCI) buses. These industry-standard buses support all main logic board I/O and up to four PCI interface cards. One PCI bus operates at a 33-MHz clock rate and supports up to three PCI cards, while the other bus can operate at either 33-MHz or 66-MHz and supports one PCI card. All PCI cards plug into slots provided on the system’s main logic board. For more information about PCI buses, see “About Peripheral Component Interconnect (PCI) Buses” on page 80.

Internal disk storage is provided by up to six hot-swappable 1-inch or 1.6-inch high,

3.5-inch wide, UltraSCSI disk drives. All six drives are supported by a 40-Mbyte per second UltraSCSI interface provided directly on the system’s main logic board. For more information about disk storage, see “About Internal Disk Drives” on page 83.

External multi-disk storage subsystems and RAID storage arrays can be supported by installing single-channel or multi-channel PCI host adapter cards along with the appropriate system software. Software drivers supporting SCSI and other types of devices are included in the Solaris operating environment.

An internal CD-ROM drive is standard on the Enterprise 250 server. The CD-ROM drive has multimedia features, which include multi-session capability and fast access for image and video data. An optional 1.44-Mbyte, 3.5-inch diskette drive is also available.

A 5.25-inch half-height (1.6-inch) bay is provided at the front of the system, which may be used to house a removable media SCSI device—such as an 8-mm tape drive, a 4-mm DDS-2 or DDS-3 tape drive, or a quarter-inch cassette tape drive. For additional details, see “About the SCSI Removable Media Bays and the External SCSI Port” on page 95.

Up to four external tape devices can be attached to the standard 68-pin Fast/Wide SCSI port provided on the system’s rear panel. Additional external tape devices can be supported with appropriate PCI host adapter cards.

The Enterprise 250 server can easily be connected to either a 10-Mbps or a 100-Mbps Ethernet by means of an auto-sensing Ethernet interface provided on the system’s main logic board. Additional Ethernet interfaces or connections to other networks, such as FDDI, ATM, or token ring, can be provided by installing the appropriate PCI interface cards. For more information, see Chapter 10.

The system console device can be either a standard ASCII character terminal or a local windowing subsystem. The ASCII terminal connects to the one of the system’s two serial ports, while a local graphics console requires installation of a PCI frame buffer card, monitor, keyboard, and mouse. System administration can also be performed from a remote workstation connected to the Ethernet.

The Enterprise 250 server provides two serial communications ports through a pair of DB-25 connectors located on the rear panel. It also provides one external, 2-Mbyte

Sun Enterprise 250 Server Owner’s Guide ♦ Revision A, June 1998

per second, bidirectional, Centronics-compatible, EPP parallel port for connecting the system to a local printer or other compatible parallel device.

Power is provided by one or two 360-watt power supplies. System conﬁgurations with two power supplies provide both N+1 redundancy and full hot swap capability. For more information about the power supplies, see “About Power Supplies” on page 87.

The Enterprise 250 server can easily be installed in a standard 19-inch rack. An optional rackmounting kit is available for installing the server into any 29- to 34-inch deep EIA 19-inch rack with at least 6 rack units (10.5 inches) of vertical mounting space and sufﬁcient load-bearing capacity.

System reliability, availability, and serviceability are enhanced by features that include:

Error correcting code on memory and all data paths

Parity checking on all address buses

Front panel status indicator lights

Disk drive health indicator lights

Hot-pluggable disk drives with easy front access

Support for RAID 0, 1, and 5 implementations

Thermal sensing and over-temperature protection

Power system monitoring and fault protection

N+1 power supply redundancy

Hot-swap power supplies with easy rear access

Automatic system recovery

Four levels of system diagnostics

Easy front or side access to all internal replaceable components

Remote System Control (RSC)

For additional details, see “About Reliability, Availability, and Serviceability Features” on page 69.

Locating Front Panel Features

The illustration below shows the system features that are accessible from the front panel with the disk access door open.

System Overview 3

Figure 1–1

For more information about front panel controls and indicators, see “About the Status and Control Panel” on page 6.

Access to the system’s internal disk drives is through a large hinged door at the front of the system. The disk access door features a key lock for added security.

When the key is in the vertical position, the door is unlocked. Make sure that the key is in this position before you close the door. To lock the door, simply turn the key 90 degrees counterclockwise and remove the key. This same key also controls the front panel keyswitch.

Locating Rear Panel Features

The illustration below shows the system features that are accessible from the rear panel.

System Overview 5

Figure 1–3

Systems may be conﬁgured with one or two power supplies, which are accessible from the system rear panel. Each power supply has two LED indicators for displaying power status and fault conditions. See “Power Supply LEDs” on page 259 for additional details.

A grounding screw is located in the upper-left corner of the rear panel. When connecting a deskside Enterprise 250 server to any rack-mounted peripheral, be sure to connect an appropriate grounding strap between the server’s grounding screw and the rack enclosure. A grounding strap prevents ground loops between the two systems and guards against possible data loss.

About the Status and Control Panel

The status and control panel includes six LED indicators and a security keyswitch. The panel is located in the top-right corner of the system front panel, as shown in “Locating Front Panel Features” on page 3.

Sun Enterprise 250 Server Owner’s Guide ♦ Revision A, June 1998

Standby

Stop-a command and terminal Break key command. This prevents users from suspending system operation and accessing the system ok prompt in order to modify OpenBoot conﬁguration parameters stored in the system’s nonvolatile memory.

This setting also prevents unauthorized programming of the system ﬂash PROM. For additional details, see “About Flash PROM Jumpers” on page 93.

This is the recommended setting for normal day-to-day operation of the system.

Places the system in standby mode by turning off power to all internal system components and placing the power supplies in standby mode. When the keyswitch is in this position, the keyboard power switch is disabled.

The LEDs consist of two types: system health indicators and fault indicators. The system health indicators light to show you that the system is functioning normally. The fault indicators light when a problem is detected in the system. Because it is important for you to know that a fault exists in the system, the fault indicators remain lit when the system is reset or switched to standby mode using the keyswitch.

When you ﬁrst power on the system, the LEDs are individually toggled on and off to verify that each one is working correctly. After that, the LEDs operate as described in the following table.

This chapter explains how to attach all cords and cables needed to get the Sun Enterprise 250 server up and running. Where software is involved, this chapter explains some of what you need to do, and points you to the appropriate software manuals for the rest.

Tasks covered in this chapter include:

“How to Install the Enterprise 250 Server” on page 44

“How to Install the Security Lock Block” on page 48

“How to Attach an Alphanumeric Terminal” on page 50

“How to Conﬁgure a Local Graphics Console” on page 51

Other information covered in this chapter includes:

“About the Parts Shipped to You” on page 43

“About Setting Up a Console” on page 49

About the Parts Shipped to You

Your system is “conﬁgured-to-order,” which means that most internal options that you order are pre-installed at the factory. However, if you ordered options that are not factory-installed (such as a monitor), these will be shipped to you separately.

In addition, you should have received the media and documentation for all appropriate system software (ordered separately). Check that you’ve received everything you ordered.

Note - Inspect all shipping cartons for evidence of physical damage. If a shipping

carton is damaged, request that the carrier"s agent be present when the carton is opened. Keep all contents and packing material for the agent"s inspection.

Unpacking instructions are printed on the outside of the shipping carton. Save the original shipping containers and packing materials in case you need to store

or ship your system. If you cannot store the shipping materials, recycle or dispose of the materials properly. Consult your local recycling authority for information.

How to Install the Enterprise 250 Server

Before You Begin

The Sun Enterprise 250 server is a general-purpose server, which you can use for many types of applications. Exactly how you set up your machine depends in some measure upon what you want it to do.

This procedure is intended to be as “generic” as possible, so as to cover the needs of most sites. Even so, you will need to make certain decisions to complete the procedure:

On which network or networks do you intend your machine to operate?

For background information about network support, see “About Network Interface Options” on page 195.

How do you want to use/conﬁgure your machine’s internal disk array?

For background information about internal disk array use, see “About Disk Array Conﬁgurations and Concepts” on page 209.

What software do you intend to load?

Software included in the server media kit or other software products may impose certain disk space or disk partitioning requirements. Refer to the documentation accompanying this software to determine those requirements.

Once you’ve answered these questions, you’re ready to begin.

What to Do

1. Verify that you’ve received all the parts of your system.

See “About the Parts Shipped to You” on page 43.

Sun Enterprise 250 Server Owner’s Guide ♦ Revision A, June 1998

2. Ensure that the system’s front panel keyswitch is in the Standby position.

See “About the Status and Control Panel” on page 6.

3. Connect the AC power cord to the power inlet at the rear of the power supply.

Connect the other end to a grounded AC power outlet.

The outlet must connect the system to a 15A circuit for North America and Japan, and to a 10A circuit for Europe. See your local electrical codes.

Insert the female end of the power cord through the plastic tie-wrap loop located to the right of the supply. Tighten the tie-wrap to secure the connection.

Figure 3–1

Note - If your server includes a second power supply, connect its AC power cord

in the same manner. You may connect the second power supply to the same circuit as the ﬁrst supply. However, for increased system redundancy, you should connect the two power supplies to separate circuits.

4. Install any optional components shipped with your system.

Many of the options ordered with your system may have been pre-installed at the factory. However, if you ordered options that were not factory-installed, see the following sections for installation instructions:

System Setup 45

“How to Install a Memory Module” on page 107

“How to Install a CPU Module” on page 110

“How to Install a PCI Card” on page 114

“How to Install a Disk Drive” on page 137

“How to Install a CD-ROM Drive or Tape Drive” on page 141

“How to Install a Power Supply” on page 155

“How to Install the Floor Casters Assembly” on page 172

“How to Install the Chassis Foot Glides” on page 176

5. Set up a console for your server.

You must either attach an ASCII terminal to serial port A or else install a graphics card and attach a monitor, mouse, and keyboard. For more information, see “About Setting Up a Console” on page 49.

6. Conﬁgure the serial port jumpers, if necessary.

Two serial port jumpers located on the main logic board are used to conﬁgure the system’s serial ports A and B for either EIA-423 or EIA-232D signal levels. The jumpers are factory-set for EIA-423 levels, which is the default standard for North American users. EIA-232D levels are required for digital telecommunication in nations of the European Community. If you require EIA-232D signal levels, see the following sections for conﬁguration instructions:

“How to Remove the Side Access Panel” on page 60

“How to Avoid Electrostatic Discharge” on page 64

“About the Main Logic Board Jumpers” on page 90

“About Serial Port Jumpers” on page 92

“How to Install the Side Access Panel” on page 62

7. Conﬁgure the network interface.

The system’s standard network interface is a switchable 10BASE-T/100BASE-TX Ethernet interface conforming to the IEEE 802.3u Ethernet standard. The interface conﬁgures itself automatically for either 10-Mbps or 100-Mbps operation, depending on network characteristics.

Supported PCI cards allow connection to additional Ethernet networks, or to token ring, FDDI, or other network types.

If you’re using the standard Ethernet interface, see “How to Conﬁgure the Standard Ethernet Interface” on page 196.

If you’re using a PCI network interface, see the documentation accompanying the PCI network card.

8. Install the security lock block to prevent unauthorized removal of the side access panel, if required.

Sun Enterprise 250 Server Owner’s Guide ♦ Revision A, June 1998

See “How to Install the Security Lock Block” on page 48.

9. Turn on power to your server.

See “How to Power On the System” on page 56. For information about the LED status indicators that appear during power-up, see “About the Status and Control Panel” on page 6.

10. Install and boot the operating system software.

See the installation manual accompanying your Solaris software. Also read the SMCC SPARC Hardware Platform Guide, which contains platform-speciﬁc information about software installation. The operating system software is ordered separately from your system hardware.

About Setting Up a Console

To install your server or to diagnose problems, you need some way to enter system commands and view system output. There are four ways to do this.

1. Attach an ACSII character terminal to serial port A. You can attach a simple terminal to serial port A. The terminal can be capable of

displaying and entering alphanumeric but not graphical data. For instructions, see “How to Attach an Alphanumeric Terminal” on page 50.

2. Establish a tip connection from another Sun system. For information about establishing a tip connection, see the OpenBoot 3.x

Command Reference Manual, an online version of which is included with the Solaris System Administrator AnswerBook that ships with Solaris software.

3. Install a local graphics console on your server. The server is often shipped without a mouse, keyboard, monitor, or frame buffer

for the display of graphics. To install a local graphics console on a server, you must install a graphics frame buffer card in a PCI slot, and attach a monitor, mouse, and keyboard to the appropriate back panel ports. For detailed instructions, see “How to Conﬁgure a Local Graphics Console” on page 51.

4. Set up a Remote System Control (RSC) console.

System Setup 49

Remote System Control (RSC) is a secure server management tool that lets you monitor and control your server over modem lines or over a network. RSC provides remote system administration for geographically distributed or physically inaccessible systems. For additional details, see “Remote System Control (RSC)” on page 75.

Use the following procedure to prevent static damage whenever you are accessing any of the internal components of the system.

Before You Begin

Complete this task:

“How to Power Off the System” on page 55

You must have the following items:

Antistatic wrist or foot strap

Sun Enterprise 250 Server Owner’s Guide ♦ Revision A, June 1998

Antistatic mat (or the equivalent)

What to Do

Caution - Printed circuit boards and hard disk drives contain electronic components

that are extremely sensitive to static electricity. Ordinary amounts of static from your clothes or the work environment can destroy components. Do not touch the components themselves or any metal parts without taking proper antistatic precautions.

1. Disconnect the AC power cord from the wall power outlet only if you will be handling the power distribution board.

The AC power cord provides a discharge path for static electricity, so you generally want to leave it plugged in during installation and repair procedures. The only time you should unplug the cord is when you service the power distribution board.

2. Use an antistatic mat or similar surface.

When performing any option installation or service procedure, place static-sensitive parts, such as boards, cards, and disk drives, on an antistatic surface. The following items can be used as an antistatic surface:

The bag used to wrap a Sun

The shipping container used to package a Sun replacement part

Sun electrostatic discharge (ESD) mat, PN 250-1088 (available through your Sun sales representatives)

Disposable ESD mat, shipped with replacement parts or options

replacement part

3. Use an antistatic wrist strap.

Attach the appropriate end to the system chassis sheet metal, and attach the other end of the strap to your wrist. Refer to the instructions that come with the strap.
