Digital PRIORIS XL Server Preface Preface The Digital PRIORIS XL Server Service Maintenance Manual is a troubleshooting guide that can be used for reference when servicing the PRIORIS XL Server series. Digital Equipment Corporation reserves the right to make changes to the Digital PRIORIS XL Server without notice. Accordingly, the diagrams and procedures in this document may not apply to the computer(s) you are servicing since many of the diagnostic tests are designed to test more than one product.
Digital PRIORIS XL Server Chapter 1 Product Description Product description Product Introduction All PRIORIS XL Servers are industry-standard, Intel microprocessor-based servers using a versatile tower enclosure. The server also features several modular CPU board designs that allow for easy server upgrades to the latest available CPU technology. The Intel i486-based CPU module employs an Intel Pentium OverDrive Ready ZIF socket to allow CPU upgrades to future Intel Pentium microprocessor technologies.

Digital PRIORIS XL Server Chapter 2 Utilities & Configuration Server Utilities & Configuration Server Utilities The following sections provide detailed instructions on running the MS-DOS utilities contained on the supplied CD-ROM startup diskette and CD-ROM. Note that these utilities can be copied to the hard disk drive. Refer to the operating system documentation for information on copying files. UPGRADE.EXE All servers have BIOS software in a read-only, non-volatile memory (ROM) chip.
Utilities & Configuration Digital PRIORIS XL Server Creating a Recovery Diskette A recovery diskette should always be prepared before attempting to upgrade the BIOS. This diskette contains a BIOS image and a program to load the image into flash memory. If a problem occurs while loading the BIOS into flash memory, a beep sounds when the server is turned on. Insert the recovery diskette into drive A or B and the original BIOS is put back in flash memory.
Digital PRIORIS XL Server Utilities & Configuration Upgrading The Server's BIOS Perform the following steps to update the server's BIOS in the flash memory and compare the BIOS image file to the flash memory: 1) 2) 3) 4) 5) 6) 7) 8) Perform steps 1 through 4 from "Creating a Recovery Diskette." Ιf the BIOS resides on a diskette, you need to use that diskette to upgrade the BIOS. Select the Upgrade Flash from Image File menu option.
Utilities & Configuration Digital PRIORIS XL Server To access SETUP.EXE: 1) 2) 3) 4) 5) 6) 7) 8) Insert the CD-ROM startup diskette into drive A. Boot the server. Allow the POST to complete. If POST detects a configuration error(s), refer to Chapter 4, “Troubleshooting” for possible causes and suggested solutions. Highlight Modify BIOS setup from the main menu, and then press [Enter]. Page 1 of Setup appears. Press the right arrow key to move the cursor to the ROM Based Setup option.
Digital PRIORIS XL Server Utilities & Configuration The SCU The SCU enables you to setup and configure the server using the menu driven items shown in figure 2-1. Depending on the installed hardware and level of server security required, you might have to access one or more of these items to properly configure the server.
Utilities & Configuration Digital PRIORIS XL Server Before Using the SCU When familiar with utility programs and their uses, refer to the appropriate sections in this chapter to setup or update the server’s configuration. Otherwise, carefully read and understand this chapter before attempting to modify the server’s configuration settings. Read any README files contained on the System Configuration Utility diskette for additional information.
Digital PRIORIS XL Server 3) Utilities & Configuration Insert the backup System Configuration Utility diskette into drive A and then soft boot (reset) the server. The SCU introductory screen appears. NOTE The SCU contains help pop-up screens for any selected menu item. Press [F1] at anytime to display a help screen. Press [Esc] to remove a help screen. 4) Press [Enter] to display the SCU Welcome screen. If no configuration errors appear, the Welcome screen displays information about the SCU.
Utilities & Configuration Digital PRIORIS XL Server The SCU automatically detects any EISA expansion boards installed on the server and configures the server accordingly. The SCU does not automatically detect ISA expansion boards. Step 3: View or Edit Details This menu item allows to examine and change the setting of each function and the resource allocated for those functions. When editing a function or resource in this step, you might have to change the switch or jumper setting.

Digital PRIORIS XL Server Utilities & Configuration SCU and Setup Options (continued) Fields Settings Comments PCI device(8) Enable device: Enabled Disabled Allows to individually enable or disable each PCI slot and onboard SCSI.
Utilities & Configuration Digital PRIORIS XL Server ROM Based Setup This option is often used by educational facilities that have public access to their servers. Disabling this option prevents unauthorized personnel from changing any server’s configuration parameters. Parallel Port and Serial Ports The server logically assigns LPTx and COMx names to: ♦ ♦ Parallel ports in the address order 378h and 278h. Serial ports in the address order 3F8h, 2F8h, 3E8h, and 2E8h. This occurs during each boot process.
Digital PRIORIS XL Server Utilities & Configuration CPU Speed This option determines the speed used by the server each time you turn it on or reboot it: ♦ ♦ Fastis the normal speed and causes the CPU to run at its rated speed. Slow(equivalent to 8 MHz) is used to reduce the effective CPU speed to be compatible with some speeddependent application programs. If an application program does not run correctly at full speed, try disabling all caches or changing the CPU speed to slow.
Utilities & Configuration Digital PRIORIS XL Server Cache BIOS ROM This option allows the server’s BIOS to be cached in the primary cache and secondary cache (if installed). This increases server performance because BIOS instructions are fetched from cache instead of RAM. Shadow Video ROM The main logic board reserves an area of DRAM for a copy of video BIOS ROM. This DRAM (called "shadow memory") is write-protected and has the same addresses as the video BIOS ROM locations.
Digital PRIORIS XL Server Utilities & Configuration PCI Device This option allows to configure the PCI slots on the server’s main logic board when adding PCI expansion boards. CAUTION The PCI Device selections for factory installed PCI expansion boards should stay at the factory default settings. Modifications can cause server failure.
Digital PRIORIS XL Server Chapter 3 Service Procedures Service Procedures Safety Requirements WARNING Static electricity collects on non-conductors such as paper, cloth, or plastic. A static discharge can be damaging even though you often cannot see or feel it.
Service Procedures Digital PRIORIS XL Server Recommended Tools The following tools will be needed for servicing Digital PC systems. Note that test equipment must be calibrated: ♦ ♦ ♦ Multimeter (4 1/2 digit) A philips screwdriver An antistatic wrist strap Other Needed Materials Cleaning agent should be an all purpose cleaner that is used in-house. Required Special Tools None. Remedial Diagnostic Test Software ♦ P R I O R I S X L QAPLUS/fe , PC Advanced Diagnostic Software, latest version.
Digital PRIORIS XL Server Service Procedures Removing the Side Panel Before removing the side panel, perform the following: 1) 2) 3) 4) Turn off power to all external devices connected to server.

Digital PRIORIS XL Server Service Procedures Expansion Slots The PRIORIS XL Server contains eight slots for installing up to seven EISA or PCI expansion boards. Five of the slots support industry-standard 32-bit EISA expansion boards. The remaining three expansion slots support 32-bit PCI local bus expansion boards. This enables the server to deliver maximum performance by using a faster data path for greater computing speed. It also improves the expandability of the server.
Service Procedures Digital PRIORIS XL Server Main Logic Board Jumpers Jumper pins allow to set specific server parameters. They are set by changing the pin location of jumper blocks. A jumper block is a small plastic-encased conductor (shorting plug) that slips over the pins. To change a jumper setting, remove the jumper from its current location with the fingers. Place the jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not to bend the pins.
