A-4 xv ------------------------------------------------------------ Preface Product Description The DECsystem 5900 system is designed for server applications, including file servers, compute servers, and network servers. It is a midrange system that uses a modular approach, based on industry standard 47.5 cm (19 in) rackmounted components. The original model, the DECsystem 5900 system, utilizes a high-performance single-card computer based on the MIPS R3000A processor. A more recent version, the DECsystem 5900/260 system is based on the MIPS R4400 processor. Both systems are housed in a single-cabinet configuration that contains a power controller, a CPU drawer, and up to four additional mass storage drawers. Document Description Since versions of the system are identical except for the actual processor (CPU/daughter card), for clarity and simplicity this manual refers to both the DECsystem 5900 system and the DECsystem 5900/260 system as simply the DECsystem 5900 system. Where unique information for a particular processor is required, pertinent differences are pointed out.

It is a highly modular system that has many configuration capabilities. The basic configuration is a single-cabinet uniprocessor. The original DECsystem 5900 system is based on a high-performance single-module computer that utilizes the MIPS R3000A processor. The DECsystem 5900/260 system utilizes a MIPS R4400 processor. All versions of the system are referred to in this manual as the DECsystem 5900 system. Where unique information for a particular processor is required, pertinent differences are pointed out. The DECsystem 5900 system uses the following devices: · Up to fourteen 32-Mbyte memory modules · 1-Mbyte NVRAM memory for Prestoserve(TM) support · Internal storage for up to 28 SCSI devices · Support for all TURBOchannel devices that conform to the TURBOchannel specification This chapter describes the following parts of the DECsystem 5900 system: · Enclosure contents and options · CPU drawer contents and options · Mass storage drawer contents and options · Power controllers and power supplies · External storage options · Power requirements · Cables and buses DECsystem 5900 Enclosure 1-1 1.1.1 Enclosure Description The DECsystem 5900 system uses a free-standing H9A00 enclosure with rackmounted drawers, shown in Figure 1-1, and is designed to be used in a computer room environment. It normally rests upon four levelers, but comes equipped with wheels for easy installation and placement. The cabinet may be accessed by both the front and rear doors. Use the front door to turn on and turn off the system, and to access removable media or the drawers. Use the rear door to access cable connections, ports, and the power controller. The front doors have magnetic latches to keep the doors closed; both front and rear doors can be locked and unlocked with a key (12-26339-01) or with a 1/4-inch hex wrench. Figure 1-1 DECsystem 5900 Enclosure ! Front door # Hex wrench " Front door latches 1-2 DECsystem 5900 Enclosure The DECsystem 5900 system consists of: · H9A00 cabinet · Drawers: CPU drawer One mass storage drawer for devices Optional second CPU drawer Up to 3 additional mass storage drawers (optional) · Power controller · Network, data, power cables and SCSI bus(es) The DECsystem 5900 cabinet includes trim panels, called skirts, which are attached to the bottom during installation. The location of the CPU drawer in relation to mass storage drawers varies according to the options ordered when the system was shipped. See Figure 1-2 and Figure 1-3 for examples of how drawers or filler panels might be positioned. Filler panels cover unused enclosure slots, as well as slot 0, which contains the power controller.

Each drawer has its own specific cooling arrangements, including blowers or fans; the cabinet itself has no cooling fans or blower. 1.1.1.2 Enclosure Power Controller The DECsystem 5900 enclosure uses a single-phase ac power controller to supply power to the cabinet, located in the bottom rear of the H9A00 enclosure. Switches, shown in Figure 1-4 and defined in Table 1-1, all face toward the rear of the enclosure, and are accessed through the rear enclosure door. There are two models of power controllers, a 120 V version (used in the US), and a 220 V version for international use. The 120 V US model has an attached ac power cord; the international model has a removable cord for the country in which it is used. Figure 1-4 Power Controller Switches and Outlets !

The power controller distributes power at the same voltage at which it enters the cabinet, that is, 120 V nominal or 220 V nominal, 50/60 Hz. A three-pin connector cable from the power controller to the CPU drawer allows for a single point of system power control: the upper front switch of the CPU drawer. (The remote/local switch must be set to remote to allow for this.) To organize and protect the many cables and buses attached to the CPU drawer, they are routed through a cable arm which extends and retracts as the drawer is pulled out and pushed in. Figure 1-5 depicts a sample power cable/bus configuration for the DECsystem 5900 system. DECsystem 5900 Enclosure 1-7 Figure 1-5 Sample Power Cable/Bus Configuration !

When the power controller remote/local switch is in the remote position (up), the upper switch on the front of the CPU drawer controls power to the entire system. When the Remote/Local switch is in local mode (down), the individual drawers must be turned on or off manually. Each individual drawer contains its own ac power switch. Power within a particular drawer is available if all of the following conditions are met: · AC power is available into the cabinet. · 1/8-A fuse in power controller is intact. · The power controller breaker switch is on. · The drawer 's power sequence cable is plugged in at the power controller. · The CPU drawer 's main power switch is in the on position (this assumes that the power controller is switched to remote mode). · The drawer 's power switch is on. 1.1.1.3 CPU and Mass Storage Drawers The DECsystem 5900 system is shipped complete with all drawers ordered by the customer, and filler panels over unused drawer slots. The minimum configuration is one CPU drawer and one mass storage drawer. Each drawer contains one or more components of the DECsystem 5900 system. These components may include the following: · In the CPU drawer: System module CPU/daughter card Two or more memory modules NVRAM module TURBOchannel option slots TURBOchannel options (if any) TURBOchannel Extender Adapter module (in option slot 0) TURBOchannel Extender module Power supply Blower Power cabling Connectors for Enet, SCSI, and communication ports DECsystem 5900 Enclosure 1-9 · In the mass storage drawer: Fixed media disks Removable media tape drives, floppy drives, and CD-ROM drives Power supply SCSI cabling Power cabling Other storage devices may be attached externally to the DECsystem 5900 system. 1.1.1.3.1 Drawer Design The drawers have been designed for efficiency and serviceability, and include the following features: · Slide-out access · Latches to prevent accidental removal · Individual power control · Completely installable as an upgrade Each drawer has six 5/16-inch hex screws to hold it in place in the cabinet for shipping.

The DECsystem 5900 system will be shipped with a minimum of two 32-Mbyte SAMs. 1.2.4 Prestoserve A 1-Mbyte MS02-NV memory module is installed in the last memory slot, slot 14. It supports the Prestoserve NFS accelerator. Slot 14 is only used for the MS02-NV. 1.2.5 TURBOchannel The system module contains three TURBOchannel option slots. One of these slots is preconfigured with an adapter module, the TURBOchannel Extender Adapter module, that is used to connect a TURBOchannel Extender module. The remaining two slots may be used for one dual or two single TURBOchannel option modules. TURBOchannel is an I/O interface which enables 100 Mbyte per second connection to optional devices such as: PMAZ (single-ended SCSI) PMAD (Ethernet) DEFZA (FDDI) As shown in Table 1-8 and Figure 1-7, there are three TURBOchannel option slots on the rear panel of the CPU drawer. TURBOchannel slot 0 contains a TURBOchannel Extender Adapter module connected to the TURBOchannel Extender module (TCE), located in the upper rear compartment of the CPU drawer. TCE is a standard feature of the DECsystem 5900 system, and provides space for the use of one single, dual, or triple TURBOchannel slot option in the DECsystem 5900 system without occupying all of the system module TURBOchannel slots. (Only one option may be used in the TCE whether it is a single, dual, or triple slot option.) Table 1-8 TURBOchannel Slots ------------------------------------------------------------ Slot Module ------------------------------------------------------------ 0 TURBOchannel SCSI controller (contains Extender Adapter module), ' in Figure 1-7 1 TURBOchannel SCSI controller, +@ in Figure 1-7; for example, PMAZ 2 TURBOchannel SCSI controller, +B in Figure 1-7; for example, DEFZA 3 System module, & in Figure 1-7; CPU, system, and memory ------------------------------------------------------------ DECsystem 5900 Enclosure 1-35 The purpose of the TURBOchannel Extender module is to allow a two- or three- slot TURBOchannel option module to be connected to the DECsystem 5900 system and physically take up only one TURBOchannel slot. This leaves two slots available for other TURBOchannel options. Without the TURBOchannel Extender module, certain TURBOchannel options could use up all three slots. 1.2.6 SCSI Interface The system module contains a 53C94-based DMA SCSI interface similar to previous Digital RISC systems which will interface with up to seven SCSI devices. In order to control additional (optional) mass storage drawer devices or drivers, one or more TURBOchannel SCSI controllers (PMAZ) are required (each SCSI controller controls 7 SCSI devices). A fully populated DECsystem 5900 system would have 28 SCSI devices: seven on the system module port, seven each on two PMAZ modules (slots 1 and 2), and seven more on a PMAZ located on the TCE (which is connected to slot 0 via the TURBOchannel Extender Adapter module; see Figure 1-7). In each mass storage drawer there are two separate SCSI buses. Each bus has five SCSI connectors. The two SCSI buses can be connected to contain seven SCSI devices (single bus configuration) for a total of seven SCSI devices allowed. The SCSI buses may be left unconnected, and terminated separately (split bus configuration) if so desired. For more information on single and split configurations, see Section 4.6. A terminator must be located at the end of each SCSI bus. On each separate SCSI bus (one or two per mass storage drawer) the individual devices are tagged with identity (ID) numbers. No two SCSI devices on the same bus may have the same ID number. If SCSI devices are added, they must be marked with an appropriate ID sticker. The factory-set configuration is depicted in Table 1-9. Table 1-9 SCSI ID Factory Configuration ------------------------------------------------------------ Device ID ------------------------------------------------------------ CPU SCSI adapter 7 First removable media device 5 Boot disk or first disk 0 Remaining disks, in order 1, 2, 3, 4, 6, 5 Remaining removable media devices 6, 4 ------------------------------------------------------------ 1-36 DECsystem 5900 Enclosure Ethernet Interface The Ethernet hardware is the LANCE-based design used in previous products. Communications Interface Two RS-232 ports are provided on the system module. Although these ports provide full modem support in the hardware, the firmware does not support full modem control. 1.3 DECsystem 5900 Cables and Buses This section lists the network and power cables and SCSI buses used by the DECsystem 5900 system which are not in a drawer (either CPU or mass storage). 1.3.1 Drawer Cables and Buses A set of power cables and SCSI buses for each of the four possible mass storage drawers is present in the DECsystem 5900 enclosure when it is shipped, whether or not a full complement of four mass storage drawers is ordered.

If it sticks, carefully use a screwdriver to pry up the bracket without touching the device. 2. Disconnect the power and SCSI leads if the bracket contains a device (see the section of this chapter which pertains to the particular device). Mark the cables for easy identification when they are reconnected. 4-12 Mass Storage FRU Removal and Replacement 3. To replace or install a drive bracket containing a device in the mass storage drawer, reverse the above procedure. Figure 4-8 depicts the removal of a drive bracket and device from one position in the drawer; others may be oriented a different way, but are removed in essentially the same manner. Figure 4-8 Removing a Drive Bracket To remove a device from a drive bracket, remove the bracket from the mass storage drawer as instructed above. Remove the Phillips screws (four, two on each side) and lock washers from the bracket, and slide the device out of the bracket (see Figure 4-9). To replace or install a new device, reverse the above procedures. If you are replacing the device, note the orientation of the connectors to the bracket before removal so that you can mount the replacement in the same manner. Mass Storage FRU Removal and Replacement 4-13 If you are installing a new device, all connectors should face toward the middle of the drawer, and be on the right-hand side as you face the connectors. See Figure 4-10 for an example. Figure 4-9 Removing a Device from a Drive Bracket 4-14 Mass Storage FRU Removal and Replacement Figure 4-10 Device Orientation Within a Drawer 4.4.3.2 Removable Media Filler Panels Removable media devices are always located in the front right-hand bracket(s) in the mass storage drawer, where the disks or tapes may be inserted and removed through the opening on the right front side of the drawer. Depending upon the combination of removable media devices chosen by the customer (if any), the removable media slots on the drawer will be covered by various filler panels which must be removed to service devices behind them. Four different panels may be present on the drawer; each panel has a top flange which is fitted under the top of the slot, and each is attached by two screws at the bottom (see Figure 4-11).

Devices in the mass storage drawer must be configured and connected before turning on the system. All mass storage drawers in the DECsystem 5900 system are ordered in a specific factory-installed configuration as specified by the customer/system manager (this includes mass storage upgrades ordered at a later date). Two cabling configuration choices are available: · Single bus configuration (see Figure 4-28 for mass storage drawer 1, and Figure 4-29 for mass storage drawer 2) · Split bus configuration (see Figure 4-30 for mass storage drawer 1, and Figure 4-31 for mass storage drawer 2) 4.6.1 Altering the Factory-Set Configuration The customer/system manager may wish to alter the configuration of a mass storage drawer; the options and advantages are listed in Table 4-3. Table 4-3 Configuration Option Choices/Advantages ------------------------------------------------------------ Configuration Option Advantages ------------------------------------------------------------ Single bus Preserves SCSI slots for other drawers/devices Split bus Improves processing speed and efficiency for heavily used devices in the same drawer ------------------------------------------------------------ 4.6.1.1 Single Bus Configuration For a single bus configuration, you must install a jumper between the SCSI ID 0 device and the SCSI ID 5 device as depicted in Figure 4-28 (mass storage drawer 1) and Figure 4-29 (mass storage drawer 2). The jumper connects the two buses in a mass storage drawer; the resulting single bus configuration is terminated on the rear of the drawer next to the SCSI signal input. 4-38 Mass Storage FRU Removal and Replacement Figure 4-28 Single Bus Configuration for Mass Storage Drawer 1 !

In this configuration both buses must be terminated inside the drawer. See Figure 4-30 (mass storage drawer 1) and Figure 4-31 (mass storage drawer 2). The split bus configuration can improve throughput by connecting two SCSI controllers to one mass storage drawer. Figure 4-30 Split Bus Configuration for Mass Storage Drawer 1 !

Signal cable " Terminator # Signal cable $ Terminator 4-42 Mass Storage FRU Removal and Replacement 4.7 Identifying and Replacing a Faulty SCSI Device A faulty device may be located using the ULTRIX UERF error log and ROM- based diagnostics, which will indicate the SCSI bus that the device is on (and therefore which drawer the device is in). The device ID pinpoints the particular device within the drawer. For detailed instruction, see the DECsystem 5900 Service Guide, EK-D590A-PS-001. 4.7.1 Procedure for Installing a New SCSI Device ------------------------------------------------------------ Caution ------------------------------------------------------------ Digital recommends that you use Digital-supplied buses intended for interconnecting SCSI devices. Digital also recommends that you power all units on the SCSI controller from a common power source. The proper operation of any SCSI controller that uses cable assemblies or buses not supplied by Digital, or not configured in accordance with Digital's recommendations, is not guaranteed. ------------------------------------------------------------ Use the following procedure to install a device in a mass storage drawer: 1. Bring down the ULTRIX operating system. 2. Get the current system and drive configuration. At the console prompt type the cnfg command. Then type a cnfg x of the system module (3) and each PMAZ (x = the slot number 0-3) and write down the drive numbers on each PMAZ. Remember that you can have a maximum of 7 SCSI devices on each SCSI bus (up to 4 SCSI buses). Discuss this with the customer/system manager, decide the new SCSI address to be used, and determine any changes needed to existing device addresses. ------------------------------------------------------------ Note ------------------------------------------------------------ Duplicate SCSI ID addresses cannot be used on any one SCSI bus; the same ID may appear (only once) on each SCSI bus in the system, however. ------------------------------------------------------------ 3. Shut off the system and/or the mass storage drawer(s) to be reconfigured. To shut off one mass storage drawer, turn off one power switch on the mass storage drawer (either one, if your version has two). Mass Storage FRU Removal and Replacement 4-43 4. Set the address (SCSI ID) of the devices to 0-6, depending on the other addresses on the SCSI bus (see Section 4.8). Do not conflict with other addresses on the SCSI bus(es). Put the appropriate address label on the bracket which contains the drive. 5. If this is an internal device: a. Install it in the mass storage drawer. For details on installing devices in a particular version of the mass storage drawer, see Section 4.4.3 (for mass storage drawer 1) or Section 4.5.2 (for mass storage drawer 2). b. Connect the power cable and SCSI signal bus to the device. Procedures for specific devices are located in the section of this chapter devoted to that device. 6. If this is an external SCSI device, connect the SCSI signal bus to the CPU drawer. 7. Ensure that the appropriate ID label appears on the top surface of each device which was added or reconfigured. 8. Turn on the system/mass storage drawers and make sure (>>cnfg x) shows the drive(s) you installed and other drives/devices. 9. Run the SCSI send diagnostics and target tests on the device(s) to verify that they work. ------------------------------------------------------------ Caution ------------------------------------------------------------ Be careful not to write on other drives if you use the w option with the target test. ------------------------------------------------------------ 10. Boot the system and allow the customer/system manager to set up the system to recognize the device(s). ------------------------------------------------------------ Note ------------------------------------------------------------ Detailed instructions and illustrations for physically removing/installing and disconnecting/connecting a particular device are located in the appropriate section of this chapter for that device. ------------------------------------------------------------ 4-44 Mass Storage FRU Removal and Replacement 4.8 SCSI IDs This section describes the setting of SCSI IDs. 4.8.1 Default SCSI Device IDs SCSI default settings for the DECsystem 5900 system are listed in Table 4-4. The settings listed give optimal performance on most systems. Table 4-4 DECsystem 5900 SCSI Device ID Default Settings ------------------------------------------------------------ Device ID ------------------------------------------------------------ CPU SCSI adapter 7 First removable media device 5 Boot device or first device 0 Remaining devices, in order 1,2,3,4,6,5 Remaining removable media devices 6,4,3,2,1,0 ------------------------------------------------------------ ------------------------------------------------------------ Note ------------------------------------------------------------ No devices should ever use SCSI ID 7, as this is reserved for the SCSI controller(s). ------------------------------------------------------------ 4.8.2 Setting SCSI IDs Digital sets each SCSI device to a default SCSI ID setting before the equipment leaves the factory. These default settings should be changed only when the server is configured with more than one device. When adding a SCSI device to the DECsystem 5900 system (or reconfiguring a mass storage drawer) it can be necessary to change the ID (address) of affected SCSI devices. The Digital services representative is responsible for changing the SCSI ID settings as part of the reconfiguration process. In most instances, it will only be necessary to ensure that there is not a SCSI ID conflict. When each SCSI device is added or reconfigured, a label should be placed on the top (visible) surface indicating what SCSI ID (address) it is. This will help diagnose ID conflicts, which are bound to occur occasionally in both manufacturing and at customer sites. Mass Storage FRU Removal and Replacement 4-45 4.8.2.1 SCSI Jumpers and Switches Varying means are employed (sets of switches, jumpers, incremental switch, programming via front panel, and so on) to set the SCSI ID and parity, depending on the particular device. Table 4-5 identifies methods applicable to devices common to the DECsystem 5900 system. Table 4-5 Common Devices and SCSI ID Method Used ------------------------------------------------------------ Device Series SCSI ID set by: ------------------------------------------------------------ RZ57 Jumpers TLZ04 Jumpers TLZ06 Switches TZ30 Switches TZ85 Switches TZK10 Jumpers TKZ09 Switches RRD42 Jumpers RX26 Switches TSZ07 Programming via front panel TKZ08 Incremental switch StorageServer 100 Switches ------------------------------------------------------------ On devices with jumpers, the SCSI ID is set by inserting (in) or removing (out) any of three jumpers in a specific combination. For the location of jumpers and the proper settings for a particular device, see the section in this chapter pertaining to that device. On devices with sets of switches, the SCSI ID is set by moving any or all of the switches to on or off. Incremental switches show a number which increments up or down when the switch is pushed. Some devices employ the front panel to set the address. For the method employed, and the location of switches on a particular device, see the section in this chapter pertaining to that device. 4-46 Mass Storage FRU Removal and Replacement ------------------------------------------------------------ Caution ------------------------------------------------------------ To change SCSI ID switches, use a pen or small pointed object to move the jumper; do not use a pencil point. Graphite particles can damage the device. ------------------------------------------------------------ 4.9 Removing and Installing Storage Devices This section describes the removal and installation of storage devices. 4.9.1 Nonremovable Media Devices Contained in Mass Storage Drawers This section describes the removal and installation of nonremovable media storage devices in a mass storage drawer. 4.9.1.1 Removing/Installing an RZ57 The RZ57 is a full-height device entirely self-contained in the mass storage drawer (it is a nonremovable media device).

The FRU part number for an RX26 includes an assembled adapter interface module, and utilizes a drive ID switch to identify the FDD interface in addition to SCSI ID switches. It is necessary to remove the adapter interface module from the device if either the SCSI ID or the drive ID needs to be set. Removing an RX26 To remove an RX26, mark and disconnect the power and SCSI leads to that particular device (see Figure 4-39), and remove the device from the drawer. See Section 4.4.3 if you have a mass storage drawer 1, or Section 4.5.2 if you have a mass storage drawer 2. (To identify mass storage drawers 1 and 2, see Section 4.3.) Installing an RX26 To install an RX26, there are two switch settings to accomplish: the drive ID switch, and the SCSI ID switches. Both of these settings require the removal of the adapter interface module (see Removing/Installing RX26 Adapter Module). After setting the SCSI and drive IDs, reinstall the RX26 by reversing the above procedure (see Removing an RX26.) Make sure to align the front of the device with the filler panel. Mass Storage FRU Removal and Replacement 4-57 Removing/Installing RX26 Adapter Module To remove or replace the adapter interface module, disconnect the signal cable from the module to the device at the device end. Remove the four screws which attach the bracket to the device, and lift out the device. See Figure 4-40. Removing/Installing RX26 Adapter Brackets Unless you are replacing the adapter interface module itself, it should not be necessary to remove the adapter brackets from the adapter. If necessary, the adapter brackets are attached to the adapter by means of four screws (two each). See Figure 4-41. Setting RX26 Drive ID Switch The RX-series drive ID switch is a slide switch on the corner of the device itself which must always be set to identify the particular FDD interface to which the device responds. The factory setting is ``0''. An RX26 in the DECsystem 5900 system must be set to ``2''. See Figure 4-42. To access the drive ID switch, you must remove the adapter interface module from the device as described in Removing/Installing RX26 Adapter Module. ------------------------------------------------------------ Note ------------------------------------------------------------ Make sure that the drive ID switch on an RX26 (lower right-hand rear corner) in a DECsystem 5900 system is always set to ``2''. Be careful not to confuse the RX-series device identifier with the SCSI ID switches on the side of the adapter (see Figure 4-42). ------------------------------------------------------------ 4.9.2.2.1 Setting RX26 SCSI ID Switches You must set the SCSI ID address of the device: To access the SCSI ID switches, you must remove the adapter interface module from the device as described in Removing/Installing RX26 Adapter Module. 1.
