This chapter de­ scribes the placement of the XMI PIU in both the system and expander cabinets and the contents of the two kits. It also lists XMI configuration rules. Sections include: · XMI PIU Placement and Rules · XMI PIU Kit Contents 1­2 Introduction 1.1 XMI PIU Placement and Rules The XMI PIU takes up two of four quadrants of space in the bot­ tom of either a system or expander cabinet. The XMI card cage is installed in either the right or left front quadrant and extends into the rear quadrant. Figure 1­1 System and Expander Cabinet XMI PIU Placement Introduction 1­3 Figure 1­1 shows the quadrant designation for system and expander cabi­ nets. XMI PIUs are installed in the bottom of either cabinet with the card cages and power regulators installed in the front. The XMI PIU requires two quadrants of space: quadrants 1 and 2 if the card cage is installed on the left, and quadrants 3 and 4 if it is installed on the right when you face either cabinet. From the front of either cabinet the XMI PIU must be to the left of a VAXBI PIU if one is installed. The following rules apply: 1. XMI PIUs in cabinets a. XMI PIUs are placed in the bottom of cabinets. b. A maximum of two XMI PIUs can be placed in a cabinet. c. A maximum of four XMI PIUs can be placed in a system. 2. XMI PIU Configuration Rules a. Each XMI PIU occupies two of the bottom quadrants: 1 and 2 or 3 and 4. The XMI PIU occupies quadrants 1 and 2 when a VAXBI PIU is installed. b. The XMI bulkhead has 20 dual I/O panels. One is used for the I/O cable from the IOP. 3. XMI Configuration Rules a. Of the 14 slots on the XMI, 12 are available for I/O devices. Two slots are reserved; slot 7, for the T2030­YA, the clock module, and slot 8, for the T2028­AA, the DWLMA module. b. The first option on an XMI must reside either in slot 1 or slot 14 to terminate the bus. If the option is a two­module option, the mod­ ule with the XMI corner must be in slot 1 or 14. c. If the cabinet has a VAXBI PIU, the T2018 module (XBIA+) must reside in slot 1 of the XMI backplane. 1­4 Introduction 1.2 XMI PIU Kit Contents The DWLMA XMI PIU option has two variants: one for a system cabinet and the other for an expander cabinet. The only differ­ ence between the two kits is the length of the cable that goes from the IOP in the system cabinet to the I/O bulkhead. Figure 1­2 shows the XMI PIU assembly. Figure 1­2 XMI Card Cage Assembly Introduction 1­5 The contents of the two kits follows: · The XMI PIU card cage assembly consists of two major pieces: · The card cage itself with the power regulators which plugs into either cabinet from the front. The clock module is already installed in the card cage. · The rear cable enclosure, consisting of the enclosure and the bulk­ head panel door that plugs into either cabinet from the back. Fig­ ure 1­2 shows the two pieces. (See Section 2.2 for installation.) · The DWLMA adapter module is placed in slot 8 of the XMI. (See Sec­ tion 2.5 for installation.) · The 4 to 1 cable is placed between the I/O bulkhead and the XMI backplane. (See Section 2.3 for installation.) · Either the 4.5 foot or 10 foot cable connects the IOP module and the I/O bulkhead. (See Section 2.4 for installation.)

The 4.5 foot cable is in the system cabinet kit, and the 10 foot cable is in the expander cabinet kit. Installation of the XMI PIU 2­1 Chapter 2 Installation of the XMI PIU Five tasks are necessary to install an XMI PIU. They are: · Preparing the Cabinet · Installing the Card Cage Assembly · Installing the 4 to 1 Cable · Installing the IOP Hose Cable · Installing the DWLMA 2­2 Installation of the XMI PIU 2.1 Preparing the Cabinet After you determine the XMI PIU quadrant location, you must re­ move the airflow plates located below the blower and above the quadrants you will be using. Figure 2­1 Airflow Plate Installation of the XMI PIU 2­3 Take the following steps to prepare the system: 1. Perform an orderly shutdown of the system. 2. Turn the keyswitch to Disable. 3. Determine which quadrants will house the XMI PIU (in the system or expander cabinet). See Section 1.1 for placement rules. 4. Open the front and rear doors of the cabinet. If you are installing the XMI PIU in an expander cabinet, you will need access to the rear of the system cabinet also. 5. Shut the circuit breaker on the AC power box off by pushing down on the breaker. The AC power box is above the blower and to the left in both cabinets. 6. If you are installing the PIU in an expander cabinet, drop the skirts below the rear doors of both cabinets. 7. Remove the two airflow plates from the front and rear of the cabinet (see Figure 2­1). These slide out of the cabinet and should be labeled and saved. (If the PIU is removed, these plates must be replaced to maintain proper airflow in the cabinet.) 8. The bulkhead door on the rear cable enclosure of the XMI PIU comes hinged on the left. If the XMI PIU is placed in the cabinet on the left when viewed from the rear (quadrants 3 and 4), the door should be hinged on the right. If you need to change the hinges, do that now, following the procedure in Appendix A. 2­4 Installation of the XMI PIU 2.2 Installing the Card Cage Assembly The BA651­AA card cage assembly consists of two parts: the card cage assembly with the clock module and power regulators, and the rear cable enclosure. First install the card cage assembly and then the rear enclosure. Figure 2­2 Installing the XMI PIU Installation of the XMI PIU 2­5 To install the XMI PIU: NOTE: Before installing the PIU, inspect the electromagnetic interference (EMI) gaskets; return the option if they are damaged. 1. Ground yourself to the cabinet with the antistatic wrist strap from the Electrical Safety Kit. 2. Place the XMI card cage half into the cabinet by lining up the rollers on the PIU with the slides in the cabinet. Now push the card cage into the cabinet until it seats. 3. Line up and only slightly tighten the two captive screws (slotted) at the top of the PIU, 3 in Figure 2­2. 4. Install the two Phillips head screws at the bottom of the card cage se­ curing the PIU to the cabinet, 4 in Figure 2­2. Tighten the two cap­ tive screws mentioned in step 3 to 27 inch­pounds. 5. Be sure the I/O bulkhead door opens in the correct direction before proceeding to step 6. See Section 2.1, step 8. 6. At the back of the cabinet, install the rear cable enclosure lining up the rollers on the PIU with the slides in the cabinet. 7. Line up and only slightly tighten the two captive screws (slotted) at the top of the enclosure. 8. Install the two Phillips head screws at the bottom of the cable enclo­ sure securing the back of the PIU to the cabinet. Tighten the two cap­ tive screws mentioned in step 7 to 27 inch­pounds. Tightening these screws compresses the EMI gaskets between the two halves. 2­6 Installation of the XMI PIU 2.3 Installing the 4 to 1 Cable The 4 to 1 cable, part number 17­03061­01, is installed between the XMI backplane and the I/O bulkhead. Figure 2­3 Placement of the 4 to 1 Cable Installation of the XMI PIU 2­7 The 4 to 1 cable is labeled for easy, correct installation. The bulkhead end of the cable is easily identified by the bulkhead plate and the receptacle for the IOP cable. The XMI backplane end has four connectors labeled DL, DR, EL, and ER. To install the cable: 1. Remove the plastic shield from the XMI backplane. 2. Figure 2­4 shows the I/O bulkhead door. If the XMI PIU is installed on the left, the bulkhead plate of the 4 to 1 cable goes in A5; if it is on the right, the bulkhead plate goes in A1. Select and remove the cor­ rect panel from the I/O bulkhead door. 3. The IOP connector is offset on the bulkhead plate. When the plate is installed in a system cabinet, the connector is to the left of center. When the plate is installed in an expander cabinet, the connector is right of center. Install the bulkhead end of the 4 to 1 cable in the bulkhead door by passing the cables through the door and secure by using the two screws removed from the plate in step 2. 4. The DWLMA adapter goes in slot 8. Slot 7 is used for the clock mod­ ule and has no connectors. Slot 8 is to its right on the XMI backplane. See Figure 2­3. 5. Install the cable marked DL into the left receptacle of row D, slot 8. 6. Install the cable marked DR into the right receptacle of row D, slot 8. 7. Install the cable marked EL into the left receptacle of row E, slot 8. 8. Install the cable marked ER into the right receptacle of row E, slot 8. 9. Replace the plastic shield. Figure 2­4 I/O Bulkhead Panel Designations 2­8 Installation of the XMI PIU 2.4 Installing the IOP Hose Cable The IOP hose cable, part number 17­03085­01 or 17­03085­02, con­ nects the IOP in the system cabinet and the I/O bulkhead. The longer hose, the ­01 variation, is used when the PIU is installed in an expander cabinet. Figure 2­5 shows the IOP cable routing for both system and expander cabinets. Figure 2­5 IOP Cable Installation and Routing Installation of the XMI PIU 2­9 The IOP cable is labeled for easy and correct installation. The IOP end is labeled IOP, and the bulkhead end is labeled PIU. To install the cable: 1. Plug the IOP end of the cable into one of the IOP module connectors and secure the end of the cable. 2. Route the cable according to Figure 2­5. 1 shows the routing for the cable in a system cabinet, and 2 shows the routing for a cable to an expander cabinet. 3. Plug the PIU end of the cable into the bulkhead connector end of the 4 to 1 cable you just installed and secure the end of the cable. 4. Once the cable has been installed, replace the skirt at the back of the cabinet. 2­10 Installation of the XMI PIU 2.5 Installing the DWLMA The DWLMA is installed in slot 8 of the XMI card cage. The XMI PIU comes with the clock card already installed in slot 7. Slot 8 is to the left of slot 7 when looking into the card cage. Figure 2­6 Installing the DWLMA Installation of the XMI PIU 2­11 To install the DWLMA: 1. At the front of the cabinet, ground yourself using the ESD strap. 2. Install the DWLMA, the T2028­AA module, in slot 8. Slot 8 is the slot to the left of the clock module already installed. Before installing and cabling all sorts of I/O options, you might want to verify the PIU installation by proceeding to the Verification chapter. Verification 3­1 Chapter 3 Verification This chapter describes the acceptance procedure and troubleshooting guidelines for the XMI PIU. See the Advanced Troubleshooting manual for more information. Sections include: · Restore Power and Check Self­Test Results 3­2 Verification 3.1 Restore Power and Check Self­Test Results Install a supported XMI option with an XMI corner in either slot 1 or 14 to terminate the XMI bus. Restore power to the system and check the self­test results to see that the XMI PIU is functioning properly. Example 3­1 Sample Self­Test Display Verification 3­3 To verify that the XMI PIU is functioning properly: 1. Insert a supported XMI option into either slot 1 or 14 to terminate the XMI bus. The module you install must have an XMI corner on it. 2. Power on the system and examine the self­test results to determine whether the XMI PIU passes. Example 3­1 shows sample self­test re­ sults. Two XMIs are shown in the example. The + at the end of the line marked 1 shows that the XMI connected to the C0 hose is functioning. The - at the end of the line marked 2 shows that the XMI connected to the C1 hose is not functioning. Lines C0, C1, C2, and C3 correspond to IOP ports (see Figure 3­1). In Example 3­1 the XMI connected to IOP port C1 is failing. If the C line indicates a problem, check all the cabling and retest. If the prob­ lem continues, follow the troubleshooting procedures in your system's Advanced Troubleshooting manual. To verify that each slot in the backplane works, do the following: 1. Install a "known good module" in the slot you wish to test. 2. Power on the system. 3. Examine the self­test results to determine whether the slot is working. 4. Repeat steps 1 through 3 for each slot. If a slot fails, return the option. If the XMI PIU passes verification, con­ tinue with the installation of XMI options. Figure 3­1 IOP Port Diagram Moving Hinges on the Bulkhead Door A­1 Appendix A Moving Hinges on the Bulkhead Door The XMI plug­in unit comes with the rear bulkhead door hinged at the left. The door opens properly when the enclosure is in the rear right quadrant (Q2). When the enclosure is in the rear left quadrant (Q4), the door should be hinged on the right so that the hose is moved as little as possible when the door is opened. This appendix describes how to change the hinges. A­2 Moving Hinges on the Bulkhead Door A.1 Moving the Hinges of the Bulkhead Door In addition to moving the hinges from one side of the bulkhead door to the other, the EMI finger stock and the plunger fasteners must be moved. Figure A­1 Bulkhead Doors on the XMI PIU Rear Cable Enclosure Moving Hinges on the Bulkhead Door A­3 Figure A­1 shows two bulkhead doors; one hinged left and the other hinged right. Follow these steps when moving the hinges on the doors from one side to the other. The steps assume the door is hinged left. 1. Remove the door by unscrewing the shoulder bolt hinges at the top and bottom. Note that the nylon washers are between the enclosure and the door. 2. Move the plastic spacer on the bottom right flange of the enclosure to the bottom left of the enclosure (where the bottom hinge used to be). 3. Remove the EMI finger stock from the top flange on the enclosure. 4. Using two 3/8 inch wrenches, remove the plunger fastener on the top flange of the enclosure and reinstall it one hole to the left of its origi­ nal location. Put the plunger in its hold open position to secure the "top" wrench and hold the "nut" under the flange with the other wrench and remove or tighten. 5. Reinstall the EMI finger stock. 6. Remove the EMI finger stock from the bottom of the door. 7. Using two 3/8 inch wrenches remove the plunger fastener on the bot­ tom of the door and reinstall it one hole to the left of its original loca­ tion. Put the plunger in its hold open position to secure the "top" wrench and hold the "nut" under the flange with the other wrench and remove or tighten. 8. Reinstall the EMI finger stock on the door. 9. Press the door into the enclosure allowing the EMI finger stock to hold it in place. 10. Reinstall the shoulder bolt hinges on the right. Be sure to place the nylon washers between the enclosure and the door.
