Chapter 1. General information

Major components of the expansion unit

The orange color on components and labels in the expansion unit indicates hot-swap or hot-plug components. You can install or remove these components while the expansion unit is running. For information about installing hot-swap and hot-plug components, see Chapter 4, “Installing and replacing components,” on page 23.

The blue color on components and labels indicates touch points, where a component can be gripped, a latch moved, and so on.

The following illustration shows the locations of major components in your expansion unit.

Note: The illustrations in this publication might differ slightly from your hardware.

Hot-swap ESMs

Hot-swap power supply with fan units

Hard disk drives

What your expansion unit offers

The expansion unit provides several features for easy operation, including:

Customer replaceable units (CRUs)

The CRUs in your expansion unit are: Ultra320 hard disk drives, ESMs, and power supply with fan units.

Fault indicators

All CRUs have fault or status light emitting diodes (LEDs) to indicate hardware failures.

Switch selectable Box ID and user configuration settings

The ESM contains five sets of configuration switches that you can set according

your configuration. For detailed information about these switches and their

settings, see Chapter 2, “ESM configuration switches,” on page 15.

Redundant cooling and power capabilities

Expansion unit models 1RU and 1RX use a dual ac input power system. This means both power switches must be turned on for proper redundant operation. The redundant cooling of the fans in your expansion unit enables continued operation if one fan fails. Your expansion unit comes with two 500-watt hot-swap power supply with fan units, which provide redundant power for many expansion

unit configurations. If the average load on your expansion unit is less than 500 watts and a problem occurs with one of the power supplies, the other power supply can meet the power requirements.

Expansion unit model 2RX uses a dual dc input power system. For detailed information about working with the dual dc input power system, see Chapter 3, “Information for the -48 volt dc power model,” on page 19.

ServeRAID

™

support

Your expansion unit supports servers with ServeRAID adapters to create redundant array of independent disks (RAID) configurations.

Clustering support

Twin-tailed clustering support is a feature of the expansion unit. Clustering is a way to share SCSI buses and hard disk drives between two SCSI controllers to provide redundancy of SCSI controllers and servers. This redundancy is important if one of the controlling servers fails. If a hardware component fails after clustering is set up, another server will take ownership of the hard disk drives.

With twin-tailed clustering, you can connect two IBM ServeRAID controllers to an expansion unit. In the twin-tailed clustering environment, you can use dual-host controllers cabled separately to the expansion unit; however, only a single bus of

drives is supported. Each SCSI device on a SCSI bus must have a unique ID.

Service tip: If you use IBM ServeRAID controllers in a cluster configuration, the

termination-power LED on the back of the expansion unit is useful. The ServeRAID controller provides the signal for termination power. If the termination power LED is not lit, it indicates that a particular expansion unit is not attached to

controller that is turned on. Make a note of which expansion unit is attached to

which server before the hardware is serviced. Clustering requires additional hardware and specialized software. For more

information, go to http://www.ibm.com/pc/ww/eserver/xseries/clustering/.

Chapter 1. General information

Expansion unit bays

The following sections describe the hot-swap components of the expansion unit and the bridge card bay.

With the hot-swap features of the expansion unit, you can remove and replace a hard disk drive, power supply with fan unit, and ESM without turning off the expansion unit. You can maintain the availability of your expansion unit while a hot-swap component is removed, installed, or replaced.

Hot-swap hard disk drive bays

The following illustration shows the location of the hot-swap hard disk drive bays that are accessible from the front of your expansion unit. The expansion unit supports up to 14 IBM Ultra320 SCSI hard disk drives. These drives come preassembled in a drive tray. You install the hard disk drives in the 14 drive bays on the front of the expansion unit.

the following illustration, seven of the 14 hard disk drive bays contain hard disk

drives, and seven bays contain filler panels. To maintain proper cooling within your expansion unit, always keep a filler panel in each drive bay that does not contain a hard disk drive. For information about installing and replacing drives, see “Working with hot-swap hard disk drives” on page 24.

Bridge card bay

Hot-swap drive bays

Filler panel

Bridge card bay

Attention: Never hot-swap a hard disk drive when its green activity LED is

flashing. Hot-swap a hard disk drive only when its amber status LED is lit (not flashing) or when the drive is inactive with the green activity LED off (not flashing). Use the ServeRAID system-management software to set the hard disk drive state to “defunct” and then you can hot-swap it.

The following illustration shows the location of the bridge card bay. This bay is accessible from the front of the expansion unit. You can replace the bridge card, but you must turn off the expansion unit before doing so. For more information about replacing a bridge card, see “Replacing a bridge card” on page 26.

This section contains instructions for turning the expansion unit on and off under normal and emergency circumstances.

Turning on the expansion unit

you are turning on the expansion unit after an emergency shutdown or power

outage, see “Turning on the expansion unit after an emergency” on page 12.

Complete the following steps to turn on the power for the initial startup of the expansion unit.

Verify that:

All cables are properly attached. Both power cords are plugged into the back of the expansion unit and into

properly grounded electrical outlets.

All hard disk drives are locked securely in place.

The configuration switches are set correctly. See Chapter 2, “ESM configuration switches,” on page 15.

Check the system documentation for all the hardware devices you intend to turn

and determine the proper power-on sequence.

Note: Be sure to turn on the expansion unit before or at the same time as you

turn on the server.

Turn on each device, based on the power-on sequence that is described in the documentation that comes with the device.

Turn on both power supplies on the back of the expansion unit. The expansion unit might take a few seconds to turn on. During this time, you

might see the fault (amber) and the power (green) LEDs on the expansion unit turn on and off intermittently. When the power-on sequence is complete, only the power (green) LEDs on the front and back should remain on.

Chapter 2. ESM configuration switches

This chapter provides general information about ESM functionality as it relates to ESM configuration switch settings. The ESM configuration switches control how power is supplied to the expansion unit and what expansion unit services are enabled (for example, switching between a rack configuration and a tower configuration or switching between a single bus and a dual-bus configuration.) In a dual-bus configuration, each bus uses seven drives. A single-bus configuration uses all 14 drives.

ESM contains five sets of configuration switches, shown in the following

illustration.

SW5 SW3 SW4

Box-ID switch

(SW2)

SW1

Note: If both ESMs are installed, the ESM on the left must have valid switch

settings. The switch settings on the ESM that is installed in the right bay are ignored. If only one ESM is installed, it must be in the left bay.

Configuration switches are summarized in Table 2 and described in this section.

Configuration switch SW1 is a five-position switch that is mounted on the ESM and is accessible from the rear of the expansion unit. The five switch positions are set as follows:

Switch positions 1 through 4 - Reserved Switch position 5 - Remote power control disable When switch position 5 is set to Off, the ESM will enable the power

supplies when the termination power (TERMPWR) is active in any external SCSI port. This means that the expansion unit will be powered

and off automatically when the host server is powered on and off or when TERMPWR is disabled. When switch position 5 is set to On (the default setting), power on and off is not controlled by the TERMPWR signal, but by the power on/off switches on the power supplies.

Box ID switch SW2

Box ID switch SW2 is a 10-position rotary switch that sets the expansion unit ID using values 0 through 9. System-management software, such as IBM Director or IBM ServeRAID Manager, uses this ID when it provides data and alerts for the expansion unit.

Configuration switch SW3 — SCSI ID configuration switch

Configuration switch SW3 defines the SCSI bus ID configurations. The user should prevent a SCSI ID conflict in a specific bus mode. SCSI bus mode is controlled by configuration switch SW4.

There are two SCSI buses (bus 1 and bus 2) in the expansion unit. Each bus uses seven SCSI ID numbers. Each hard disk drive within the expansion unit has a unique SCSI bus and ID assignment, based on its physical location in the expansion unit and the setting of configuration switch SW3. This prevents a SCSI ID conflict in a specific bus mode.

Chapter 4. Installing and replacing components

This chapter provides instructions for installing and replacing components.

Installation guidelines

Before you begin installing your expansion unit, read the following information:

Read the safety information beginning on page 37 and the guidelines in “Handling electrostatic discharge-sensitive devices” on page 40. This information will help you work safely with your expansion unit and options.

Make sure that you have an adequate number of properly grounded electrical outlets for your expansion unit and other devices that you will connect to the expansion unit.

Back up all important data before you make changes to disk drives. You do not need to turn off the expansion unit to install or replace hot-swap

power supply with fan units, hot-swap hard disk drives, or ESMs. The orange color on components and labels identifies hot-swap or hot-plug

components. You can install or remove hot-swap and hot-plug components while the expansion unit is running.

The blue color on components and labels indicates touch points, where a component can be gripped, a latch moved, and so on.

For a list of supported options for your expansion unit, go to http://www.ibm.com/us/compat/.

System reliability guidelines

help ensure proper cooling and system reliability, make sure that:

Each of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield installed in it.

Each of the power-supply bays has a power supply installed in it. There is adequate space around the expansion unit to allow the enclosure

cooling system to work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the expansion unit. Do not place objects in front of the power supplies with fan units.

You have replaced a failed power supply with fan unit within 48 hours. You have replaced a hot-swap hard disk drive within 2 minutes of removal with a

new drive or filler panel.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your expansion

unit. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

reduce the possibility of damage from electrostatic discharge, observe the

following precautions:

Limit your movement. Movement can cause static electricity to build up around you.

Handle the device carefully, holding it by its edges or its frame.

not touch solder joints, pins, or exposed circuitry. not leave the device where others can handle and damage it.

While the device is still in its static-protective package, touch it to an unpainted metal part of the expansion unit for at least 2 seconds. This drains static electricity from the package and from your body.

Remove the device from its package and install it directly into the expansion unit without setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on your expansion unit enclosure or on a metal surface.

Take additional care when handling devices during cold weather. Heating reduces indoor humidity and increases static electricity.

Working with hot-swap hard disk drives

This section explains how you can increase the expansion unit capacity by adding more drives or replacing existing drives with larger capacity drives.

Before you remove drive CRUs, review the following information:

Hot-swap hardware

You can replace a failed hard disk drive without turning off the expansion unit. Therefore, you can continue to operate your system while a hard disk drive is removed or installed. These drives are known as hot-swap drives.

Hard disk drives

Your expansion unit supports IBM Ultra320 SCSI hard disk drives. These IBM drives come pre-installed in a drive tray, ready for installation. (Do not detach the drive from the tray.) This drive and tray assembly is called a customer replaceable unit (CRU). You can install the drives directly into the

drive bays on the front of the expansion unit. Be sure to record the location information for each drive before you remove it. Ensure that you keep track of the drives and their corresponding bays. Also, record the location information in the Installed-device records section of the Installation Guide.

installing new drives, remove the filler panels and save them for future use. Each of the 14 bays must contain either a filler panel or a hard disk drive.

Hard disk drives

You can install only slim Ultra320 hot-swap hard disk drives in the expansion unit.

Replacing a hot-swap hard disk drive

Hard disk drive problems include any malfunctions that delay, interrupt, or prevent successful I/O activity between the hosts and the hard disk drives in the expansion unit. This includes transmission problems between the host controllers, the ESMs, and the drives. This section explains how to replace a failed drive.

Attention: Failure to replace a hard disk drive in the correct bay might result in

loss of data. If you have data stored on the hard disk drive, label the drive before you remove it. Then, when you replace the drive, install it in the same drive bay from which you removed it.

Check the hardware and software documentation provided with your server to see if there are restrictions regarding hard disk drive configurations. Some system SCSI configurations might not allow mixing different hard disk drive capacities or types within an array.

Complete the following steps to replace a hot-swap hard disk drive:

Read the instructions that come with the hard disk drive. Read the “Installation guidelines” on page 23 and the safety information

Appendix B. Related service information

Note: The service procedures are designed to help you isolate problems. They are

written with the assumption that you have model-specific training on all computers, or that you are familiar with the computers, functions, terminology, and service information provided in this manual.

Safety information

The following section contains the safety information that you need to be familiar with before servicing an IBM computer.

General safety

Follow these rules to ensure general safety:

Observe good housekeeping in the area of the machines during and after maintenance.

When lifting any heavy object:

Ensure you can stand safely without slipping. Distribute the weight of the object equally between your feet. Use a slow lifting force. Never move suddenly or twist when you attempt to

lift. Lift by standing or by pushing up with your leg muscles; this action removes

the strain from the muscles in your back. Do not attempt to lift any objects

that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

not perform any action that causes hazards to the customer, or that makes

the equipment unsafe. Before you start the machine, ensure that other service representatives and the

customer’s personnel are not in a hazardous position. Place removed covers and other parts in a safe place, away from all personnel,

while you are servicing the machine. Keep your tool case away from walk areas so that other people will not trip over

it.

not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.

Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately 8 centimeters (3 inches) from the end.

not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.

Remember: Metal objects are good electrical conductors.

Wear safety glasses when you are: hammering, drilling soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.

Reinstall all covers correctly before returning the machine to the customer.

Electrical safety

CAUTION: Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunication systems, networks, and modems before you open the server covers, unless instructed otherwise in the installation and configuration procedures.

Observe the following rules when working on electrical equipment.

Important: Use only approved tools and test equipment. Some hand tools have

handles covered with a soft material that do not insulate you when working with live electrical currents.

Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.

Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch

unplug the power cord quickly.

not work alone under hazardous conditions or near equipment that has

hazardous voltages. Disconnect all power before:

Performing a mechanical inspection Working near power supplies Removing or installing main units

Before you start to work on the machine, unplug the power cord. If you cannot

unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

you need to work on a machine that has exposed electrical circuits, observe

the following precautions:

Ensure that another person, familiar with the power-off controls, is near you.

Remember: Another person must be there to switch off the power, if

necessary. Use only one hand when working with powered-on electrical equipment; keep

the other hand in your pocket or behind your back.

Remember: There must be a complete circuit to cause electrical shock. By

observing the above rule, you may prevent a current from passing through your body.

When using testers, set the controls correctly and use the approved probe leads and accessories for that tester.

Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames.

Observe

the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

Regularly inspect and maintain your electrical hand tools for safe operational condition.

not use worn or broken tools and testers.

IBM EXP400 Storage Expansion Unit Type 1733: Hardware Maintenance Manual and Troubleshooting Guide

v Do

–

If an

–

Never assume that power has been disconnected from a circuit. First, check that

has been powered-off.

Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.

not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage.

not service the following parts with the power on when they are removed from their normal operating places in a machine:

Power supply units Pumps Blowers and fans Motor generators and similar units. (This practice ensures correct grounding of

the units.)

electrical accident occurs: Use caution; do not become a victim yourself. Switch off power. Send another person to get medical aid.

Safety inspection guide

The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

any unsafe conditions are present, you must determine how serious the apparent

hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock).

Explosive hazards, such as a damaged CRT face or bulging capacitor Mechanical hazards, such as loose or missing hardware

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

Check exterior covers for damage (loose, broken, or sharp edges). Turn off the computer. Disconnect the power cord.

Appendix B. Related service information

a. A

–

Check the power cord for:

third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground.

The power cord should be the appropriate type as specified in the parts listings.

Insulation must not be frayed or worn.

Remove the cover.

4. Check for any obvious non-IBM alterations. Use good judgment as to the safety

any non-IBM alterations.

Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

Check for worn, frayed, or pinched cables. Check that the power-supply cover fasteners (screws or rivets) have not been

removed or tampered with.

Handling electrostatic discharge-sensitive devices

Any computer part containing transistors or integrated circuits (Is) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the server, the part, the work mat, and the person handling the part are all at the same charge.

Notes:

Use product-specific ESD procedures when they exceed the requirements noted here.

Make sure that the ESD-protective devices you use have been certified (ISO

9000) as fully effective.

When handling ESD-sensitive parts:

Keep the parts in protective packages until they are inserted into the product. Avoid contact with other people. Wear a grounded wrist strap against your skin to eliminate static on your body. Prevent the part from touching your clothing. Most clothing is insulative and

retains a charge even when you are wearing a wrist strap. Use the black side of a grounded work mat to provide a static-free work surface.

The mat is especially useful when handling ESD-sensitive devices. Select a grounding system, such as those in the following list, to provide

protection that meets the specific service requirement.

Note: The use of a grounding system is desirable but not required to protect

against ESD damage.

Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.

Use an ESD common ground or reference point when working on a double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.

Use the round ground-prong of the ac plug on ac-operated computers.

IBM EXP400 Storage Expansion Unit Type 1733: Hardware Maintenance Manual and Troubleshooting Guide

Grounding requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
