technology; it supports up to eight processors and up to 8 GB of memory.

Two backplanes each hold six 3.5-inch hot-swappable SCSI-2 hard drives (for a total of 12 SCSI drives). The drive bays are secure behind a lockable metal EMI door. You can swap drives in or out of the system with power on. The array of drives allows easy setup of RAID applications.

A hot-swappable backplane is part of each 3.5-inch drive bay assembly for SCSI drives. The backplane is designed for wide and fast SCSI-2 devices that use the industry standard 80-pin Single Connector Attachment (SCA). Each backplane consists of two rows of three drive connectors. A system may contain one or two of these backplanes (supporting 6 or 12 drives).

Four externally accessible 5.25-inch half-height bays are available for diskette, CD-ROM, and/or tape drives.

Special Notes

Diagnostic Partition and Platform CD-ROM

All DIGITAL Server 9100 systems ship with a Diagnostic Partition and Platform CD-ROM. The Diagnostic Partition contains utilities that enable you to configure the server and run diagnostics. The Platform CD-ROM contains the same utilities as the Diagnostic Partition. In the case of a disk failure, where the Diagnostic Partition is not available, you can run these utilities from the CD-ROM and not load them on the boot disk; however, it is recommended that you run them from the Diagnostic Partition whenever possible. Some of the utilities save files to disk, and they are not able to do this when you run them from the CD-ROM.

The main purpose of the Platform CD-ROM is to enable you to install the Diagnostic Partition and its utilities (for example, if you have to replace the boot disk).

Refer to the DIGITAL Server 9100 Series System Software Guide for detailed information on software utilities.

Selecting a Fault Reporting Mechanism

The DIGITAL Server 9100 series uses a Fault Reporting mechanism called SAF-TE (SCSI Accessed Fault Tolerant Enclosure) for reporting hot-swap disk drive activity and status. All other DIGITAL Servers, as well as external Expansion Cabinets, use the DIGITAL Fault-Bus for reporting hot-swap disk drive activity and status. The Mylex RAID controllers provide support for both types of fault reporting and are shipped configured for SAF-TE when factory-installed or DIGITAL Fault-Bus when ordered as standalone options.

Special Notes

A RAID controller can be configured for SAF-TE or Fault-Bus but not both. Consequently, a RAID controller configuration with one channel connected to internal hot-swap disk drives (SAF-TE) and another channel connected to an expansion cabinet (Fault-Bus) is not supported.

DIGITAL ServerMaker

DIGITAL ServerMaker is an easy to use, interactive configuration tool for configuring and ordering DIGITAL Servers and rackmount. The ServerMaker tool guides you through a server configuration and minimizes errors. ServerMaker provides prompts and warnings as selections are made for adding options such as networking cards, RAID and SCSI adapters, hard drives, tapes, monitors, and operating systems. The result is a server parts list that can be printed or converted to an Excel spreadsheet. You can download ServerMaker from the following website location:

http://www.windows.digital.com/products/servermaker

Enhanced System Diagnostics

You can run the diagnostics from the Diagnostic Partition to isolate problems. Enhanced diagnostics are also available on the Quick Launch CD-ROM. You can create diagnostics diskettes from Quick Launch by using the Utilities option located under the Installation & Utilities button.

Removing and Installing the Covers

This chapter contains procedures for removing and installing the:

• Side covers

• Top cover

• Front bezel

Tools and Supplies Needed

You need the following tools and supplies to perform the procedures described in this chapter:

• Phillips #1 and #2 screwdrivers

• Hexagonal-head nut driver

• Standard tip screwdriver

• Antistatic wrist strap, antistatic bag, and conductive foam pad (recommended)

• The System Site Log. This document contains forms for recording information on system equipment

and components, hardware service, software products, and preventive maintenance activities. Use these forms as you set up your system for the first time, integrate new parts or software into the system, service or troubleshoot system problems, and perform preventive maintenance.

Chapter 1

Warnings and Cautions

The following warnings and cautions apply throughout this chapter. Only a technically qualified person should integrate and configure the system.

Before performing the procedures in this chapter, turn off system power and disconnect the AC power cord.

Warnings

System power on/off: The DC push-button on/off switch (a convex button) on the front panel DOES NOT turn off the system AC power. To remove power from the system, you must unplug the AC power cord. Do not remove the side panels or internal cover panels unless the AC power cord has been unplugged. If the system has internal battery backup power, you must also turn the local battery disconnect switch on the back of the server to “Off.”

WorldMark 4300 Deskside Service Guide 1-1

Removing and Installing a Side Cover

Hazardous conditions, devices and cables: Hazardous electrical conditions may be present on power,

telephone, and communication cables. Turn off the system and disconnect the power cord,

telecommunications systems, networks, and modems attached to the system before opening it. Otherwise,

personal injury or equipment damage can result.

Cautions

Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives, boards, and other

parts. This system can withstand normal levels of environmental ESD while you are hot-swapping SCSI

hard drives. However, we recommend that you perform all procedures in this chapter only at an ESD

workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap

attached to chassis groundany unpainted metal surfaceon the system when handling parts.

Chassis covers, proper cooling and airflow: For proper cooling and airflow, always install the chassis

side and top covers before turning on the system. Operating it without these covers in place can damage

system parts.

1-2 Removing and Installing the Covers

Removing and Installing a Side Cover

Removing a Side Cover

The following figure shows how to remove a side cover. The figure shows the left external side cover over the primary system board area; the procedure is the same for both side covers.

OM 04372

A Retaining screw (four at back) B Padlock at back edge (if installed)

CAUTION: For proper cooling and airflow, always replace the side covers before turning on the system; operating it with the covers removed can damage system parts.

Do not damage or displace the electromagnetic interference (EMI) strips mounted on the frame as you remove and install the cover. Replace any damaged strips, or the system may not meet EMI requirements.

To remove a side cover:

1. Observe the safety and ESD precautions listed at the beginning of this chapter.

2. Unlock padlock (if present) and remove it.

3. Remove four screws from the back edge of the side cover, and save to reinstall the cover.

4. Grip the two built-in handles at the back edge of the cover.

5. Slide cover toward the back about an inch until it stops.

6. Pull cover out from the system to disengage the bottom and top rows of tabs from notches in the chassis. Set cover aside.

WorldMark 4300 Deskside Service Guide 1-3

Removing and Installing a Side Cover

Installing a Side Cover

To install a side cover:

1. Before replacing a side cover, check that you have not left loose tools or parts inside the system. Check that cables, boards, and other components are properly installed.

2. Orient the cover so the padlock slot at the back edge fits over the loop at the back edge of the chassis. (The covers on each side are exact duplicates, but they install as a mirror image.)

3. Align the top and bottom rows of tabs on the cover with the slots in the chassis, and carefully push inward.

4. Slide the cover toward the front so the tabs engage firmly in the slots. If the cover does not slide freely all the way forward, make sure the padlock slot is correctly placed over the loop on the chassis back.

5. Attach the cover to the chassis with the four screws you removed earlier, and tighten firmly.

6. To prevent unauthorized access inside the system, insert and lock a padlock through the loop at the back (one at each side).

1-4 Removing and Installing the Covers

Removing and Installing the Top Cover

Removing the Top Cover

The following figure shows how to remove the top cover. To avoid damaging EMI strips, do not lift the cover much more than the 20-degree angle implied by the figure.

Removing the Top Cover

R etaining scr ews

OM 04371

Important: Remove side covers first. You must remove both side covers before you can remove the top cover.

To remove the top cover:

1. Observe the safety and ESD precautions listed at the beginning of this chapter.

2. Remove both side covers using the instructions in the previous section.

3. At the back, remove five retaining screws from the top cover.

4. Slide the top cover toward the rear approximately one inch. Lift the cover directly up and off of the

frame.

Removing and Installing Fans

Warnings and Cautions

The following warnings and cautions apply throughout this chapter. Only a technically qualified person should perform the procedures described in this chapter.

None of these procedures can safely be done with the system power on. To perform any procedures inside the system, turn off the system power and disconnect the AC power cord.

Warnings

System power on/off: The DC push-button on/off switch (a convex button) on the front panel DOES NOT turn off the system AC power. To remove power from the system, you must unplug the AC power cord. If the system has internal battery backup power, you must also turn the local battery disconnect switch on the back of the chassis to “Off.”

Hazardous conditions, devices and cables: Hazardous electrical conditions may be present on power, telephone, and communication cables. Turn off the system and disconnect the power cord, telecommunications systems, networks, and modems attached to the system before opening it. Otherwise, personal injury or equipment damage can result.

Cautions

Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives, boards, and other parts. We recommend that you perform all procedures in this chapter only at an ESD workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap attached to chassis groundany unpainted metal surfaceon the system when handling parts.

ESD, handling boards and modules: Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only by their edges. After removing a board from its protective wrapper or from the system, place it component-side up on a grounded, static-free surface. Use a conductive foam pad if available but not the board wrapper. Do not slide board over any surface.

Ensure complete board insertion: When installing add-in boards, be sure that the boards are completely and correctly seated in the system board connectors before applying power. Incomplete insertion can result in damage to the system board and the boards being inserted.

Board support panel, proper cooling and airflow: For proper cooling and airflow, always install the board support panel for the processor and memory boards before installing the chassis side and top covers and turning on the system. Operating the server without this support panel in place can damage system parts.

Chassis covers, proper cooling and airflow: For proper cooling and airflow, always install the chassis side and top covers before turning on the system. Operating it without these covers in place can damage system parts.

2-2 Removing and Installing Fans, Intrusion Alarm, Front Panel Control Board, and LCD

Removing and Installing Fans

The server contains identical dual removable chassis fans to cool the boards and removable media drives. The dual fan assembly provides redundant fan capability to maintain airflow in case of a single fan failure. An R2 system board configuration requires four dual fan assemblies. Some R1 systems contain two dual fan assemblies; others contain four dual fan assemblies.

CAUTION: If an R1 system contains two dual fan assemblies and you plan to install 10K RPM (or faster) disk drives, you must upgrade the system to four dual fan assemblies.

Replacement fans must be able to provide the same failure-sensing circuitry as the fans already installed. Note: Each power supply has an integral fan, but these are not separately removable and are not

described here.

Correct Airflow Direction

The removable fans pull air in from the front of the chassis so that it flows across the boards and out the back. Thus, the fans must be oriented for the correct airflow direction. Confirm correct fan orientation by checking the embossed arrows on the side of each fan as you place the fan in its bracket.

Removing and Installing the Front Panel Control Board

Restoring the Front Panel Control Board Vital Product Data

The front panel control board contains an embedded EEPROM which stores information about the server called the Vital Product Data (VPD). This information includes the vendor ID, chassis type, and product type. If you install a new front panel control board, you must restore the VPD.

The VPD is loaded from the Diagnostic Partition file eeprom.dat at the factory. If this file is present, you can use it to restore the VPD. If not, you must create it.

Perform the following steps to restore the VPD to the front panel control board.

1. Boot the Diagnostic Partition.

2. Escape to a DOS prompt by selecting “Run Utilities and Diagnostics > Remote Support > File Transfer Utils > File Download > Continue.”

3. Change to the Configuration Utility directory by entering:

cd directory

where directory is \scu for an R1 system and \model2\scu for an R2 system.

4. Check for the presence of the eeprom.dat file by entering:

type eeprom.dat

If the file is present, you are ready to restore the VPD. If not, create the file using the DOS edit utility, adhering to the file format below.

5. Restore the VPD by entering:

vpdwrite

6. Verify the VPD information by entering:

vpdread test.dat

There should be no error messages printed, and a test.dat file should be created which contains the same information as eeprom.dat.

WorldMark 4300 Deskside Service Guide 3-7

Installing and Removing 5.25-inch CD-ROM and Tape Drives

Drive Types and Placement

The system has four 5.25-inch half-height bays at the upper left front (behind the small front bezel door). These bays are intended to hold tape, CD-ROM, or other removable media drives.

Narrow SCSI drives in the 5.25-inch bays receive signals through a standard 50-pin terminated ribbon cable that connects to the SCSI B connector on the primary system board.

Service Notes

Active bus termination is needed for the 5.25-inch device cable. The narrow SCSI cable that connects to the 5.25-inch removable media drives is terminated at the end of the cable. Therefore, the SCSI bus terminations must be removed from the device.

Hard drives are not recommended in these bays. We do not recommend installing a hard disk drive in a 5.25-inch external bay, because the drive generates EMI and is more susceptible to ESD.

Save filler panels and EMI shields. System EMI integrity and cooling are both protected by having drives installed in the bays or filler panels and EMI shields covering the bays. When you install a drive, save the panel and shield to reinstall in case you should later remove the drive and not reinstall one in the same bay.

Installing or Swapping a SCSI Drive in a Hot-Swap Bay

This section describes installing a new drive in or swapping out a faulty drive from one of the 12 hot-swap drive bays.

General Guidelines

Note the following general guidelines before installing or swapping SCSI drives:

• The 3.5-inch SCSI drives must use the industry standard 80-pin Single Connector Attach (SCA) connector.

• Each drive must be installed in the carrier supplied with the drive, which enables hot-swapping. The drive is mounted in the carrier, and the carrier is inserted in the drive bay. The carrier has a locking handle that secures the drive/carrier assembly in the SCSI bay.

• If installing new drives, follow an installation scheme starting with the top left drive. Fill the bays left to right, across the top row, and then move down a row.

• For 9 GB SCA drives with the following model number only, make sure the jumper on the front of the drive is removed before installing the drive:

ST19171WC

Ultra SCSI Drive Considerations

Note the following special considerations for Ultra SCSI drives:

• Depending on the type of controller, enable the appropriate option (see the following table) for each SCSI channel that connects to a backplane populated with Ultra SCSI drives. Disable the appropriate option for each channel that connects to a backplane populated with non-Ultra SCSI drives.

If the controller is… Then enable this option for Ultra SCSI support…

Onboard SCSI channel A, B, or C or an add-in Adaptec controller

Mylex RAID

• If you enable Ultra SCSI support for a SCSI channel (SCSI IDs 0 through 6), then all drives on that SCSI I/O bus must be Ultra SCSI drives. It is possible, however, for one internal backplane to contain all Ultra SCSI drives and the other internal backplane to contain all non-Ultra SCSI drives.

CAUTION: Use supported Ultra SCSI drives only. Use of unsupported drives may result in data corruption. Ultra SCSI is supported for drives with part numbers 006-3301726 or greater. Ultra SCSI is not supported for drives with the following model numbers:

Utility

Identifying a Faulty Drive

If a fault LED (yellow light) above a SCSI drive is on steadily, this indicates that the drive below it has been flagged as faulty by the SCSI host controller. Follow the procedure described in this section to remove the faulty drive and swap in a good one.

3-16 Removing and Installing Drives and SCSI Backplanes

Drive Installation Cautions

Electrostatic discharge (ESD) and ESD protection. ESD can damage disk drives, boards, and other parts. This system can withstand normal levels of environmental ESD while you are hot-swapping SCSI hard drives. However, we recommend that you perform all procedures in this chapter only at an ESD workstation or provide some ESD protection by wearing an antistatic wrist strap attached to chassis groundany unpainted metal surfaceon the system when handling parts.

Install or swap SCSI drives without turning off power. This is one of the few system procedures that is safe to do with the system power left on. This is true only for the drive/carrier assemblies in the hot-swap bays, not for drives in any other bays.

Wait until the drive spins down. When the fault LED above a SCSI drive indicates a drive fault (steady yellow light), you can remove the drive and swap in a replacement at any time when the drive is not being accessed, without needing to power down the system. However, drive manufacturers caution against moving a drive that is still spinning because of possible damage to the spindles. Allow 1 minute for a drive to spin down and rest before removing it.

Use the correct drive carrier. Some drives use plastic drive carriers. Other drives require aluminum drive carriers. Be sure to use the drive carrier provided in the drive kit. Performance is degraded if you use a plastic drive carrier with a drive that requires an aluminum drive carrier.

SCSI Drive Status LEDs

If you are swapping out a faulty SCSI drive, you can pinpoint which drive to remove by checking the status LEDs that occur in sets of three above each of the 12 drive bays.

The following table shows the meaning of the three LEDs that are located above each drive, from left to right.

Note: This table assumes that a SCSI host controller is installed to send SAF-TE control signals to the drive fault LED.

There is no drive installed in the bay.

Installing or Hot-Swapping SCSI Drives

The procedure is basically the same to swap a drive or to install one for the first time. Perform the following steps:

1. Observe the drive installation cautions listed at the beginning of this section.

2. Open the right front exterior door (refer to the “Removing a Drive” figure).

3. Open the EMI metal panel in accordance with instructions in the “Installing the Front Bezel” section in Chapter 1.

4. If you are hot-swapping a SCSI drive, continue to step 5. If you are only installing a new drive, go to step 10.

5. Determine which drive has been flagged as faulty by reading the LEDs located above each drive bay.

carrier provided in the drive kit for these drives. Performance is degraded if you use a plastic drive carrier with a drive that requires an aluminum drive carrier.

10. Remove the new drive from its protective wrapper, and place it on an antistatic surface.

11. Record the drive model and serial number in the System Site Log.

12. Install the new drive in the drive carrier as follows. a. Orient the drive so the power and signal connector is on the top side. b. Place the carrier on top of the drive. Attach carrier using four screws of appropriate size and

length (screws not supplied). The carrier includes EMI/ESD grounding clips that make contact with the drive through two of the screws.

Note: Label all new SCSI drives.

13. Align drive/carrier assembly so it engages the guide rails in the bay.

14. Gently push the assembly into the bay until the drive docks with the backplane connector.

15. Push the locking handle on the carrier to the right until it locks around the small metal posts.

16. Close the EMI metal panel, and secure with three thumbscrews.

17. Close the front exterior panel.

3-20 Removing and Installing Drives and SCSI Backplanes

SCSI Drive Backplane Connectors

The server can have both an upper and a lower SCSI drive backplane or an upper SCSI drive backplane only. The upper and lower SCSI drive backplanes are identical.

A SCSI drive backplane:

• Is configured as a SCSI bus

• Automatically terminates the full 16-bit-wide bus

• Gets power at J10 from the power distribution backplane

• Gets signal input at J15 from one of the following sources:

– SCSI Channel A on the primary system board – SCSI Channel C on the secondary system board – An add-in SCSI adapter or RAID controller

The SCSI drives get signal input and power from connectors J5 through J7 and J12 through J14 on the backplane.

Removing and Installing a SCSI Drive Backplane

The “SCSI Drive Backplane Connector Locations” figure in the “SCSI Drive Backplane Connectors” section shows the connector locations on a SCSI drive backplane. Refer to this figure when performing the procedures in this section.

Removing a SCSI Drive Backplane

To remove a SCSI drive backplane:

1. Observe the safety and ESD precautions listed at the beginning of this chapter.

2. Remove all SCSI drive/carrier assemblies from the bays that connect to the backplane you are removing. To remove an assembly, pull its locking handle toward you to release it from the bay. Lay each unit on a flat, antistatic surface.

Note: Label all SCSI drives for proper reinstallation.

3. Remove the side cover from the side of the chassis where the SCSI hard drives are located (the right side, if viewed from the front).

4. Carefully remove the fan assemblies on this side from the chassis. Do not let the inner fan fall out of the fan assembly.

5. Label and disconnect all cables attached to the SCSI backplane (at least four cables).

6. Remove and save nine screws from the SCSI backplane. Use a right-angle #2 Phillips screwdriver to access the three screws nearest the chassis center. (Refer to the figure in the following subsection for an illustration of screw locations.)

WorldMark 4300 Deskside Service Guide 3-31

Removing and Installing a SCSI Drive Backplane

7. Lift the backplane off the two locator pins at the top. Hold it by the top edge or upper corners, being careful not to scrape it against other system components. Place the board component-side up on an antistatic surface.

Installing a SCSI Drive Backplane

To install a SCSI drive backplane:

1. Before installing a SCSI drive backplane, verify the following jumper settings:

• SCSI drive ID jumpers at J3 and J4 are set to their factory default settings

• Secondary jumper at J4 is set correctly (primary if you are installing the upper backplane,

secondary if you are installing the lower backplane)

See the following section, “Setting SCSI Backplane Configuration Jumpers,” for details.

2. Position the backplane on the SCSI drive chassis, using the screwholes as guides.

3. To align the backplane correctly, first install the two screws (marked “Screws A”) across the middle of the backplane, as highlighted in the following figure. Then install the remaining seven screws. Use a right-angle #2 Phillips screwdriver to insert and tighten the three screws nearest the chassis center.

Secure SCSI Backplane Beginning With Screws A

OM 04478

4. Reconnect all cables to the backplane. The SCSI signal cables have precise folds that are intended to help the cables fit in the space allowed and to correctly orient the pin 1 side of the cable(s) (red stripe).

5. Reinstall any boards you needed to remove to gain access to the backplane connectors.

6. Reinstall the fans.

7. Reinstall the side cover.

8. Install SCSI drives in the bays that connect to the backplane in accordance with instructions in an earlier section, “Installing or Swapping a SCSI Drive in a Hot-Swap Bay.”

9. Run the SCSISelect Utility to check system function.

Setting SCSI Backplane Configuration Jumpers

This section contains information about the following SCSI backplane configuration jumpers:

• SCSI Drive ID jumpers

• SCSI Flash Update jumper

• External Backplane jumper

• Secondary jumper

SCSI Drive ID Jumpers, J3 and J4

Program control must read the drive ID to correlate a drive fault message to the appropriate fault light over a drive bay. The SCSI microcontroller on the SCSI backplane is always set to SCSI ID 6. The various configurations allow unused SCSI IDs to be used for narrow SCSI devices like a CD-ROM or tape backup drive.

The following figure shows the location of the jumper block on the SCSI backplane. The table shows the ID configuration choices for each drive.

A jumper should be on pins 5 and 6 on J3 when the backplane is located in the host server chassis. A jumper should on pins 6 and 7 when the backplane is located in an external chassis (for example, a peripherals-only chassis). In the latter case, the jumper setting enables the backplane to assume basic enclosure services associated with the front panel. Such services are normally done by the system board in the host chassis.

If there is only one SCSI backplane in a server chassis, the backplane is jumpered as primary; this backplane is in the upper bay position. If there is more than one SCSI backplane in the chassis, the upper backplane is jumpered as primary so that it controls the single front panel fault light and reports other enclosure functions to the host system board. The second, lower backplane must be jumpered as secondary. The secondary backplane reports its functions to the primary backplane.

Updating SCSI Hot-Swap Backplane Firmware

The SCSI backplane firmware is stored in nonvolatile memory on the backplane. You can easily update the firmware without replacing the memory device. This section describes the normal procedure for updating the backplane firmware with the HSUPDAT Utility.

Once a firmware update has begun, it must be completed. The transfer immediately overwrites existing data. If an update is prematurely terminated, the normal operation mode of the backplane processor may not work correctly. A partial update may prevent entry into firmware transfer mode. You must then perform a recovery procedure (see “Recovering SCSI Hot-Swap Backplane Firmware” later in this chapter).

Command Line Format

Use the following command line format when running the HSUPDAT Utility: HSUPDAT <switches> source_file

The following table provides information about variables that you can use in the command line:

Item Description

HSUPDAT Name of the utility.

source_file

Not case-sensitive; defined as follows:

-b

-p1,

-p2

Name of the source file to be used for the update. If you do not specify the source file, the utility prints the status and version information about the processors.

Source file is in binary. The utility defaults to Intel Hex 86 format if the -b switch is not specified.

Specifies the hot-swap backplane to be updated. -p1 indicates primary controller; -p2 indicates secondary controller. Default (no -p specified) is to program both.

Using the Correct Version of the Utility and Source File

When you update the SCSI backplane, make sure you use the correct version of the source file and HSUPDAT utility.

The name of the update source file is in the format hsxxyy.hex, where xx is the major operational code version number and yy is the minor version. For example, the source file name for firmware version 1.11 would be hs0111.hex.

WorldMark 4300 Deskside Service Guide 3-37

Updating SCSI Hot-Swap Backplane Firmware

The source file you use for the update must have the same major operational code version number as the current backplane firmware. The following table shows the versions of the HSUPDAT Utility and the source file required to update different levels of firmware:

If the backplane firmware version is…

Note: R2 systems require SCSI drive backplanes which support firmware version 2.10 or later. A SCSI drive backplane replacement is required to update from 1.yy firmware to 2.yy firmware.

CAUTION: Do not attempt to use HSUPDAT Utility version 1.01 to update a SCSI drive backplane with 2.yy firmware. Doing so makes it necessary to replace the SCSI backplane. Use HSUPDAT Utility version 2.03 or greater to update a SCSI drive backplane with 2.yy firmware. Version 2.03 also supports

1.yy firmware updates.

Update Procedure

To update the SCSI backplane firmware:

1. Get an update from your customer sales representative or dealer and copy the files to a DOS-bootable diskette. You do not need to remove drives or boards for a normal update.

2. Insert the update diskette in the A: drive and reboot the system.

3. Enter the following at the DOS prompt to display a list of the files on the diskette:

dir

Then use HSUPDAT Utility Version…

1.yy or 2.

and source file version…

hs01yy.hex hs02yy.hex

4. Enter the following command to display current version information for the update utility and the firmware on both backplanes:

HSUPDAT

Two sets of firmware version information display, one for the Operating Code and one for the FLASH Loader. The FLASH Loader code is permanent and does not get updated.

Note: If the following message is displayed, ignore it:

Improper filename on the command line

Note: If for some reason the FLSHUPDT jumper on the SCSI backplane is in the update recovery position (pins 10-11 on J4), the system does not display the Operating Code version. The jumper must be in the normal (default) position (pins 9-10 on J4) for the system to display the Operating Code Version.

CAUTION: After you run the HSUPDAT Utility, do not attempt to access the hard disk drives until you power-cycle the system. If you attempt to access Mylex drives before power-cycling the system, the system marks the drives as “dead” and you must run the Mylex utilities to put them back on-line. If you attempt to access non-Mylex drives, the system displays the

Abort, Retry, Fail

message.

5. If the HSUPDAT Utility is compatible with the current firmware, enter one of the following commands to update the SCSI backplane firmware:

If the HSUPDAT Utility is not compatible with the current firmware, obtain the correct version from your customer sales representative or dealer.

6. Verify that the correct firmware version is now installed by entering the following command to

display the version information for the firmware on both backplanes:

HSUPDAT The Operating Code version should match that of the .hex file. Note: If the following message is displayed, ignore it:

Improper filename on the command line

7. When the update process completes, remove the diskette from A: drive and power-cycle the system

(turn the power off, wait a few seconds, and then turn the power on).

Recovering SCSI Hot-Swap Backplane Firmware

This section describes the procedure for recovering SCSI backplane firmware. For the normal SCSI firmware update procedure, see the previous section.

Recovery Procedure

To recover the SCSI backplane firmware:

1. Observe safety and ESD precautions at the beginning of this chapter.

2. If you have not already done so, create a bootable MS-DOS diskette and copy the update to the diskette.

3. Turn off the system, unplug the AC power cord, and turn the local battery disconnect switch to “Off.”

4. Open the right front exterior door and the metal EMI panel.

5. Remove SCSI hard drive 1 from the upper left drive bay of the primary (top) backplane. To create more working space, you may also want to remove hard drive 2. Refer to the “Installing or Swapping a SCSI Drive in a Hot-Swap Bay” section in this chapter for removal and reinstallation instructions.
