Figure 2-1 is a simplified block diagram showing physical connections between the XMI card cage and other components in the cabinet. Figure 2-1: XMI Card Cage Connections 2-2 VAX 6000 Platform Service Manual The XMI card cage is a 14-slot cage with zero insertion force (ZIF) connectors. The cage is 3 inches deeper than a VAXBI cage, providing for larger XMI modules. The backplane area extends over three of the five connector segments, which leaves two segments for I/O pins. Mounted in the center rear of the XMI backplane is a daughter card that holds the central arbiter chip. Four slots in the center of the cage have no I/O connectors, so XMI I/O adapters cannot be installed in these slots. For each optional VAXBI channel, there must be an XMI-to-VAXBI adapter. This adapter (DWMBB) consists of two modules: a DWMBB/A module in the XMI card cage and a DWMBB/B module in the VAXBI card cage. The configuration rules are listed in the DWMBB chapter of the VAX 6000 Model 300 and 400 Service Manual and the VAX 6000 Model 500 Service Manual. See the appropriate manual for the system you are servicing. XMI Card Cage 2-3 2.1.2 XMI Card Cage Specifications The XMI card cage has 14 slots and is located in the upper part of the cabinet.

XMI Card Cage 2-17 2.4 Configuring Modules in Model 300 and 400 Systems The XMI card cage design, XMI architecture, and processor model place some restrictions on the use of the slots. Only XMI modules may be placed in the XMI card cage; installing any other modules may destroy the modules. Figure 2-10: Numbering of XMI Slots CAUTION: Never attempt to insert a VAXBI module into an XMI card cage. The backplane technology for the XMI and VAXBI is similar but incompatible. Inserting a VAXBI module into an XMI card cage can destroy the module. Note that VAXBI modules are shorter than XMI modules. 2-18 VAX 6000 Platform Service Manual An XMI node takes its node number from the slot in which it resides. This is unlike the VAXBI bus where the node number assignment derives from node ID plugs inserted into the backplane for each slot. Figure 2-10 shows the numbering of the slots in the XMI card cage. Slots are numbered in hexadecimal to correspond to the self-test display. Figure 2-11 shows the maximum number of processor, memory, and I/O modules that may be installed in Model 300 and 400 systems. Slots where a module may not be installed are indicated by the letter N. Installation in all other slots is permitted. Figure 2-11: XMI Configuration Rules for Models 300 and 400 ! Slot E must contain a module. Slot E contains a DWMBB/A module when the system has a VAXBI bus. " For a Model 400 system with a vector processor, see configuration rules in VAX 6000 Models 300 and 400 Service Manual. # The total amount of memory is limited to 512 Mbytes. $ Slots 5 through A may not contain I/O modules. Any problems with the XMI cage or modules are indicated in the first three lines of the self-test display. The self-test display is explained in the VAX 6000 Models 300 and 400 Service Manual. XMI Card Cage 2-19 2.5 Configuring Modules in Model 500 Systems The XMI card cage design, XMI architecture, and processor model place some restrictions on the use of the slots. Only XMI modules may be placed in the XMI card cage; installing any other modules may destroy the modules. Figure 2-12: Numbering of XMI Slots CAUTION: Never attempt to insert a VAXBI module into an XMI card cage. The backplane technology for the XMI and VAXBI is similar but incompatible. Inserting a VAXBI module into an XMI card cage can destroy the module. Note that VAXBI modules are shorter than XMI modules. 2-20 VAX 6000 Platform Service Manual An XMI node takes its node number from the slot in which it resides. This is unlike the VAXBI bus where the node number assignment derives from node ID plugs inserted into the backplane for each slot. Figure 2-12 shows the numbering of the slots in the XMI card cage. Slots are numbered in hexadecimal to correspond to the self-test display. Figure 2-13 shows the maximum number of processor, memory, and I/O modules that may be installed in Model 500 systems. Slots where a module may not be installed are indicated by the letter N. Installation in all other slots is permitted. Figure 2-13: XMI Configuration Rules for Model 500 ! Slot E must contain a module. Slot E contains a DWMBB/A module when the system has a VAXBI bus. " For a system with a vector processor, see configuration rules in VAX 6000 Model 500 Service Manual. # The total amount of memory is limited to 512 Mbytes. Only MS65A memory is supported. $ Slots 6 through 9 may not contain I/O modules. Any problems with the XMI cage or modules are indicated in the first three lines of the self-test display. The self-test display is explained in the VAX 6000 Model 500 Service Manual. XMI Card Cage 2-21 2.6 XMI Troubleshooting When you install modules in the XMI card cage, several items need to be checked. Table 2-3 gives a checklist of items to troubleshoot. Table 2-3: XMI Troubleshooting Checklist ------------------------------------------------------------ Symptom Possible Cause ------------------------------------------------------------ No power to cages Clear plastic door not in place or not latched. Intermittent module response Poor contact at connector Loose cabling at the backplane Power connector reattached with 7/16" screw instead of 5/16" screw Module does not appear on self-test results Loose cabling at the backplane System not configured correctly. ------------------------------------------------------------ 2-22 VAX 6000 Platform Service Manual Clear plastic doors cover the XMI and VAXBI card cages. If these doors are opened when power is still on, a power interlock switch cuts off power from the regulators to either the VAXBI side or to the XMI side, depending on the door opened. Before turning power back on, make sure the clear plastic doors are in place and latched. The XMI bus requires a non-memory module in slot E. If this slot is empty, the bus will shut down. If you receive intermittent module response, or the module does not show up on self-test as being present at all, make sure the module is seated properly, and check the backplane cabling. Modules may fail self-test because of poor contact at the connector. A thorough cleaning of the gold pads on the module and of the connector in the card cage corrects this contact failure. If the connections seem to be faulty, clean the contact areas of the connector and module. Table 2-4 lists tools and supplies for connector cleaning.

The two VAXBI card cages provide one 12-slot VAXBI channel. The interface between the VAXBI bus and the XMI bus is the DWMBB option. The DWMBB/B module requires one slot in the VAXBI card cage. Figure 3-1: VAXBI Card Cage Connections 3-2 VAX 6000 Platform Service Manual The (VAX_XXXX) system uses the optional VAXBI bus for input/output. When used, two VAXBI card cages are installed in the processor cabinet. These two card cages provide one 12-slot VAXBI channel. A VAXBI expander cabinet can also be added, which can hold up to four VAXBI cages (four 6-slot channels). The VAXBI card cage has zero insertion force (ZIF) connectors. The backplane area extends over two of the five connector segments; the remaining three segments are used for I/O connections. Installed on the cage are I/O transition headers. Each VAXBI bus has its own XMI-to-VAXBI adapter (DWMBB). The DWMBB/B module of this adapter resides in the VAXBI card cage. VAXBI Card Cage 3-3 3.1.2 VAXBI Card Cage Specifications The VAXBI card cage is a 6-slot cage. (The two cages in the system cabinet are configured as one 12-slot VAXBI channel.) The VAXBI card cages are located in the upper part of the cabinet, on the left as you view the system from the front. The field-replaceable unit (H9400-AA) does not include the power bus bar assembly, the node ID plugs, the terminator, and the flexible backplane extension.

NOTE: See the Verification chapter in the (VAX_XXXX) Series Installation Guide for complete acceptance instructions. VAXBI Card Cage 3-19 3.4 VAXBI Expansion and Configuration Rules The system cabinet has two VAXBI cages configured to provide one 12-slot VAXBI channel for I/O. Slot 1 holds the XMI-to-VAXBI adapter module (DWMBB/B), leaving 11 slots for I/O modules. Four more cages can be installed in a VAXBI expander cabinet to provide four additional VAXBI channels, for a total of five VAXBI channels. A maximum of 31 slots is available for I/O adapters. Figure 3-12: Numbering of VAXBI Slots 3-20 VAX 6000 Platform Service Manual The cage and backplane were designed so that any module or node can reside in any slot (except slot 1). Since the module that drives the clock must be in slot 1, that slot is reserved for the DWMBB/B module. (See Figure 3-12 for the numbering of VAXBI slots.) VAXBI node numbers derive from node ID plugs that plug into the backplane. A node, which can be more than one module, is assigned the node number of the plug that is inserted into the slot of the module with the VAXBI Corner. Multimodule nodes must be in adjacent slots. Constraints on adding VAXBI options include: · Power requirements for the options · Memory latency time needed to access memory See Digital's Systems and Options Catalog for VAXBI option configurations in (VAX_XXXX) systems. See Appendix B of the VAXBI Options Handbook for power requirements of various options. The DWMBB/B module requires 6 amps. VAXBI Card Cage 3-21 3.5 VAXBI Troubleshooting When you install modules in the VAXBI card cages, several items need to be checked. Table 3-5 gives a checklist of items to troubleshoot. Table 3-5: VAXBI Troubleshooting Checklist ------------------------------------------------------------ Symptom Possible Cause ------------------------------------------------------------ No power to cages Clear plastic door not in place or not latched. Intermittent module response Poor contact at connector Loose cabling at backplane Power connector reattached with 7/16" screw instead of 5/16" screw Module does not appear on self- test results Loose cabling at backplane System not configured correctly Modules display unusual fail- ures after FBE is removed and replaced Check FBE pins for buckling or other damage ------------------------------------------------------------ 3-22 VAX 6000 Platform Service Manual Clear plastic doors cover the VAXBI and XMI card cages. If these doors are opened when power is still on, a power interlock switch cuts off power from the regulators to either the VAXBI side or to the XMI side, depending on the door opened. Before turning power back on, make sure the clear plastic doors are in place and latched. You can then push the reset switch on the H7206-B power and logic unit (see Figure 5-11) to return power to the system. If you receive intermittent module response, or the module does not show up on self-test as being present at all, make sure the module is seated properly, a node ID plug is in place, and the backplane cabling is correct. Modules may fail self-test because of poor contact at the connector. A thorough cleaning of the gold pads on the module and of the connector in the card cage corrects this contact failure. If the connections seem to be faulty, clean the contact areas of the connector and module. Table 3-6 lists tools and supplies for connector cleaning.

For 50 Hz systems, the same output is first routed to the transformer (part number 16-28393-01) which lowers the phase voltages to the required input range of the H7206-B. The H405 AC power controller monitors the state of the cabinet thermostat mounted at the top of the cabinet. The thermostat is a normally closed thermal switch. The H405 also monitors the sense switch in the main circuit breaker. The sense switch is normally closed when the circuit breaker is in the On position. If the thermal switch opens (overtemperature condition) or the sense switch opens (main circuit breaker is Off), the H405 removes power from the cabinet by opening an internal AC contactor. The battery backup unit, if present, is disabled by the Fail Safe Enable signal from delivering its 250V DC source to the H7206-B power and logic unit.

It is located in the bottom of the cabinet. Figure 5-18: H7236-A Battery Backup Unit (Front View) 5-36 VAX 6000 Platform Service Manual Table 5-12: H7236-A Battery Backup Unit Specifications ------------------------------------------------------------ Parameter Description ------------------------------------------------------------ Part Number: H7236-A Location: Bottom center of cabinet Dimensions: 10.5" H x 8.75" W x 28.0" D Weight: 98 lbs Cables: 17-00442-27 J2 to H405 17-02485-01 BBU to H7206-B 300V 17-02975-01 BBU to H7206-B signal Service From: Front and rear of cabinet, doors open Tools Required: Phillips screwdriver ------------------------------------------------------------ When the system detects a power failure, it signals the H7236-A battery backup unit (BBU). If the power failure lasts less than one second, the BBU's ride-through capability enables the system to function as if nothing has happened. (Disk drives located in the bottom of the cabinet, however, are shut down upon detection of the power failure.) If the power failure lasts longer than one second, Power Fail Interrupt is signaled and the following actions are initiated: · The H7236-A supplies full power to the XMI card cage for at least 500 milliseconds while the processors write their cache data back to memory. · If the system has a VAXBI bus, the operating system stores all current VAXBI processes during the same 500 millisecond period. Power to the VAXBI card cage is then disabled. · The operating system stops. · The H7236-A continues to power the XMI card cage so memory is refreshed and data is held. If system power returns within 10 minutes, a warm restart is performed. The operating system continues from the point at which it stopped. If the power outage is longer than 10 minutes, the H7236-A shuts off to prevent the battery from draining. Memory data is lost, since memory is cleared when power is restored.

Before removing the module from its ESD box, place the box on a clean, stable surface. Be sure the box will not slide or fall. Never place the box on the floor. And be sure no tools, papers, manuals, or anything else that might damage the module is near it. Some components on this module can be damaged by a 600-volt static charge; paper, for example, can carry a charge of 1000 volts. 3. Hold the module only by the edges, as shown in Figure C-1. Do not hold the module so that your fingers touch any 25 mil devices, leads, or XMI fingers. Be sure you do not bend the module as you are holding it. 4. Be sure nothing touches the module surface or any of its components. If anything touches the module, components or leads can be damaged. This includes the antistatic wrist strap, clothing, jewelry, cables, components on other modules, and anything in the work area (such as tools, manuals, or loose papers). Module Handling C-3 C.2 Inserting Modules Figure C-2: Inserting the Scalar Processor in an XMI Card Cage Figure C-3: Inserting the Vector Processor in an XMI Card Cage C-4 VAX 6000 Platform Service Manual You must take special precautions when moving the processor modules in or out of the XMI card cage. 1. Be sure, when inserting a module in or removing it from the XMI card cage, that no part of the module comes in contact with another module or a cable. 2. When you swap out a module, place it in an ESD box or on an ESD mat before you install the new module. If you place the module on an ESD mat, make sure the mat is on a stable, uncluttered surface, with side 1 of the module facing up (the side with the heat sinks). Do not put it on the top of the system cabinet. And never slide the module across any surface. The leads on the components are fragile and can be damaged by contact with fingers or any surface. 3. Hold the XMI card cage handle while removing or inserting the module. If it is not held in place, the handle can spring down and damage the module. 4. When inserting a module in the card cage, grasp it as shown in Figure C-2 or in Figure C-3, being careful not to touch any 25 mil devices, and slide it slowly and gently into the slot. 5. Do not attach the repair tag to the module. Place the repair tag in the plastic bag attached to the bottom of the ESD box. Allowing the repair tag to come in contact with the module can cause damage to a component.
