SBP-205 Installation The MaxPro tower server or ProRack rackmount system has been fully set up by CSS Laboratories before delivery. The passive backplane and single board computer(s) have been installed and configured at the factory. Typically, no single board computer (SBC) installation is necessary. However, the modular design of the MaxPro and ProRack systems enables you to customize them to meet specific needs. Swapping out the single board computer(s) is one way the MaxPro and ProRack systems can be customized and upgraded. Overview The SBP-205 connects to any CSS Laboratories passive backplane through one EISA connector with a PCI bus extension. This SBC connector socket combination is located on the passive backplane. Installing the SBP-205 to a Passive Backplane It is not necessary to remove the passive backplane from the system chassis in order to remove or install the SBP-205. To prepare the system and SBC for installation: 1. Power down the system and remove the power cord and any other external connectors. 2. Open the system case. • CSS Laboratories Section 2 – Using the SBP-205 • 12 • Follow the instructions in the MaxPro or ProRack User Guide that accompanied your system. 3. Inspect the SBP-205 jumper settings and reset them as needed. The SBP-205 jumper switches are pre-set at the factory. If any changes are needed, it is easier to make them before installing the SBC. See Jumper Switches for information and procedures. 4. Install the processor and the DIMMs. It is easier to install a processor and DIMMs to the SBC before the SBC itself is installed. See Installing and Removing Memory and Installing and Removing a Processor for procedures. To remove an installed SBC: 1. Unplug any EIDE or other data cables and port connectors from the SBC. 2. Remove the retaining screw located at the rear of the system case. 3. Lift the SBC from the sockets on the passive backplane. All MaxPro and ProRack series chassis come with protective stabilizer bracket is part of the chassis. This bracket must be removed in order to remove the SBC. Refer to the MaxPro, ProRack User Guide for removal procedures. 4. Remove the DIMMs from the installed SBC. See Installing and Removing Memory for procedures. 5. Remove the processor from the installed SBC. See Installing and Removing a Processor for procedures. To install the SBP-205: 1. Position the SBP-205 over the sockets on the passive backplane. Make sure that the connector pins are facing down. The SBP-205 will install in only one direction. The correct SBC sockets are the EIDE with the PCI bus extension. See Figure 4 – Passive Backplane and Figure 5 – SBC Installed to Passive Backplane for sample illustration using the PB11109 passive backplane. 2. Gently press the SBP-205 into the sockets until it clicks into place. 3. Replace the retaining screw at the rear of the system case. 4. Connect the EIDE cables, along with any other data cables and external port connectors. 5. Close the system case. 6. Reconnect the power cord and the external connectors, and power up the system. As the system boots, the BIOS will detect the SBP-205 settings. You may need to manually reconfigure the system. See BIOS Configuration for procedures to configure the BIOS and CMOS. • CSS Laboratories Section 2 – Using the SBP-205 • 13 • SBC Connector Slots (EISA Connector and PCI Bus Extension) Figure 4 – Passive Backplane Figure 5 – SBC Installed to Passive Backplane Jumper Switches The SBP-205 jumper switches are pre-configured at the factory. Jumpers are used to configure the processor bus frequency and to clear CMOS contents. Jumper Switches Overview The Pentium III processor uses a clock multiplier to match the processor core frequency with the speed of the processor bus—the speed at which data travels into and out of the processor. Four jumper switches determine the processor bus frequency. Another jumper temporarily clears the CMOS contents. • CSS Laboratories Section 2 – Using the SBP-205 • 14 • NOTE: With the new Pentium III processor, it is not necessary to set jumper switches to determine the bus processor frequency. The Pentium III processor is self- adjusting. Two-pin jumpers are described as jumped, “on” or “in” with the small plastic jumper cap on, or not jumped, “off” or “out” with the jumper cap off. Jumpers with more than two pins are described by numbering the pins. Each of the SBP-205 jumpers has the number “1” stamped on the board next to that jumper’s pin number one. The jumper cap placed over a particular combination of pins, such as 1-2 or 2-3, determines the jumper setting.

JP2 JP6 JP7 JP5 Figure 6 – SBP-205 Jumper Switches • CSS Laboratories Section 2 – Using the SBP-205 • 15 • Setting Jumper Switches Setting jumper switches is easiest with the SBP-205 removed from the system. While the jumper switches are accessible with the SBP-205 installed, it might be necessary to remove one or more adapter cards if they restrict access to the jumpers. To access the jumper switches: 1. Power down the system and remove the power cord and any other external connectors. 2. Open the system case. Follow the instructions in the MaxPro or ProRack User Guide that accompanied your system. 3. Locate the jumper switches you wish to set. 4. Temporarily remove any adapters or connectors that restrict your access to the jumper switches. 5. If necessary, temporarily remove the SBP-205 from the system. For SBP-205 removal and installation procedures, see Installing the SBP-205 to a Passive Backplane. To temporarily clear the CMOS: CMOS contains the system BIOS configurations. Temporarily placing a jumper cap on JP17 pins 2-3 clears the contents of the CMOS chip.

Care must still be taken to ensure that the system case won’t be kicked or struck. An impact could damage disk drives. ƒ Do not place the MaxPro or the ProRack near any heat source that may damage it, such as heaters, direct sunlight, etc. ƒ Do not eat, drink or smoke near the system. ƒ Use a surge protector with the MaxPro or ProRack and any peripheral devices. Power surges can damage or destroy the SBP-205 or other components. Surges can also destroy data on the hard drives. ƒ Allow a space of at least eight inches around your system for proper ventilation. ƒ Do not plug the MaxPro or ProRack into the same electrical circuit with a “noisy” electric motor, such as a blender or a vacuum cleaner. ƒ Ground yourself by touching the system case before touching any hardware or software. This discharges the static electricity in your body. (Static electricity can damage components). ƒ Keep the system clean and free of dust. Use commercially available dust covers. Troubleshooting Troubleshooting Tools The first and most important sign of trouble is that a particular device simply is not working. The other main indicator is that you receive error messages, either on power up or when attempting to use a particular device. The SBP-205 functions only in conjunction with other components, including a passive backplane and optional adapter cards. Most problems with the SBP-205 will be traceable to connections or to software including the BIOS. Several common physical problems and problems with related devices are discussed in this section and in the Troubleshooting Using System Utilities topic later in this section. There are three main troubleshooting tools: 1. Direct inspection 2. Troubleshooting using system utilities • CSS Laboratories Section 3 – Maintenance and Troubleshooting • 23 • The various Windows operating systems, for example, provide system information, data on problem devices and other troubleshooting utilities. 3. Troubleshooting Tables These tables deal with problems and solutions that are primarily physical in nature, but can also involve reconfiguring software installations. The Troubleshooting Tables build upon and work with what you learn by doing the initial inspection steps. Use all three tools together as necessary. Troubleshooting by Direct Inspection First, make sure that the power cord(s) and all external connectors are properly connected. Then make sure that the system itself and its peripherals are turned on, particularly any peripheral that isn’t working. Next, answer this question: Have you installed any new hardware or software since the system was last working properly? If you have just added any new hardware or software, then remove the software or device and see if the system now runs correctly. If it does, reinstall the new device and/or software. Reinstalling often resolves hardware conflicts and solves the problem. Troubleshooting Using System Utilities Different operating systems provide different arrays of troubleshooting and system utilities. The steps outlined here provide an example of using the Windows NT system utilities to pinpoint problem devices. 1. Access the Control Panel from the Start Menu or from the Windows desktop. 2. Double-click the Devices icon. This will display the Devices window. Figure 14—Windows NT Devices Window 3. Select the problem device and click the HW Profiles button. This will display the Device window. 4. Click the Enable button if the device is incorrectly disabled. • CSS Laboratories Section 3 – Maintenance and Troubleshooting • 24 • Figure 15—Windows NT Device Window 5. Click the Disable button if the device is enabled and is still not functioning properly. 6. Adjust the resource settings as necessary using the BIOS setup utility. The resource settings include the IRQ and the I/O address currently in use by the device. This often is where a device problem can occur, as the IRQ or the I/O address settings can be the same as those for another device on the system. If there is a device conflict, reinstalling the software drivers will usually reassign IRQs and I/O addresses and often will resolve the conflict and the problem. Windows NT does not provide direct control of device resource allocations or hardware conflict information. Individual devices must be installed using the BIOS utilities. See BIOS Configuration for more information. Windows 2000 addresses this deficiency, and provides more detailed system information and greater device installation control from within the operating system. Troubleshooting Tables The following tables list common problems and the basic handlings to resolve those problems. The handlings are only the most likely steps to take, suggested guidelines. Use them in conjunction with the direct inspection and system utilities tools discussed earlier. • CSS Laboratories Section 3 – Maintenance and Troubleshooting • 25 • SBP-205 Troubleshooting Tables GENERAL PROBLEMS HANDLING The system will not power on. 1.
