Installation Overview 0 Figure 1. Installing a SCSI adapter, . . overview F’lgure 1 presents an overview of installing the adapter in an HP 9000 Series Xxx computer system. The procedure is slightly different for the HF’ 9000 Series T6xx and will be noted where different. Installing the SCSI adapter consists of the following major steps: Shut down the operating system using shutdown -h 0 (not reboot) and turn computer power off.
Prepare to Install the Adapter Refer to your computer manuals for any additional information necessary to install the adapter in your computer system. Before installing the adapter, you should perform the following steps: n Observe antistatic precautions. n Verify product contents. n Record adapter identification information. n Gather tools and accessories. Observe Antistatic Precautions This product contains electronic components that can be damaged by an electrostatic discharge.
Record Adapter Information Record the part number and date code of the adapter for future reference. If your adapter requires service in the future, the part number and date code will be needed by HP service personnel. This information is provided on stickers affixed to the adapter. See the example below (note that your information might differ from the example).
Shut Down the Operating System and Switch Off the Computer 1. Before installing the adapter, shut down the computer operating system (using shutdown -h 0, not reboot). Refer to your computer system manual for proper shutdown procedures to avoid corruption or loss of data. 2. Turn computer system power off. 3. Unplug the computer’s power cord. 4. Turn power off on all peripheral devices.
Set SCSI Adapter DIP Switches DIP switches on the SCSI adapter are used to set the SCSI address of the adapter. These switches are preset at the factory at address 7 and should not need to be changed unless there are multiple SCSI initiators on the same SCSI bus. This situation would only occur in a multi-host environment, that is, if you are using the ServiceGuard product. If you need to set the DIP switches, the location of the switches on the SCSI adapter is shown in figure 2.

If Necessary, Remove the Termination Resistors If the SCSI Adapter is installed in the middle of a SCSI bus, that is, not at the end as shown in figure 1 on page 12, the termination resistors on the SCSI Adapter should be removed. (This would only occur in an HA solution with greater than two CPUs, or if a V cable is used.) See figure 3 for the locations of the termination resistors (remember, the component locations on the two adapters are identical except for the front faceplate).
Install the Adapter For the HP 9000 Series Kxxx computer system, the HP AZ969A SCSI adapter can be installed in a slot in either the core I/O or the HP-HSC expansion I/O. For the HP 9000 Series T6xx computer system, the HP A3644A SCSI adapter is installed in a slot in the HP-HSC I/O bus converter. 20 Instaua.
Install the HP A2969A SCSI Adapter in an HP 9000 Series Kxxx To instaIl the HP A2969A SCSI adapter in an HP 9000 Series I&xx computer, perform the following steps: 1. Shut down the operating system and turn power off to the computer. (See page 15.) 2. Wear a grounding wrist strap that is connected to the core I/O or expansion I/O bulkhead. 3. Remove the core I/O or expansion VO from the computer. Refer to the computer system manual for the necessary steps to remove the core I/O or expansion I/O.
Slot cover screws Figure 4. slot locations Slot covers / Orange stripe indicating top (matches strip on computer) 6. Install the SCSI adapter into the slot in the core I/O or expansion I/O. 7. Insert the mounting tabs (located on the SCSI adapter faceplate) into the slots in the core I/O or expansion I/O bulkhead, then line up the SCSI adapter connector with the receptacle on the core I/O or expansion I/O adapter. Figure 5 shows the SCSI adapter beiig installed on the expansion I/O.
Figure 5. Installing the adapter in the I/o bulkhead 8. Press down on the rear of the SCSI adapter until its connector is fully inserted into the receptacle on the core I/O or expansion I/O adapter. 9. Secure the adapter by tightening the two retaining screws (Iocated on the front of the core I/O or expansion YO bulkhead). 10. If the SCSI adapter was installed in the expansion I/O, record the expansion I/O slot number for future reference. 11. Re-install the core I/O or expansion I/O.
Install the HP A3644A SCSI Adapter in an HP 9000 Series T6xx The HP A3644A SCSI adapter (see figure 6) is physically identical to the HP A2969A adapter except for the front bulkhead, thus, the locations of the DIP switch and the termination resistors are the same. The HP A3644A adapter is installed in an HP-HSC I/O bus converter, which is then instaIled in the HP 9000 Series T6xx computer. The HP-HSC YO bus converter is shown in figure 7.
Figure 7. HP-H!3C I/O bus converter To install the HP A3644A SCSI adapter in an HP 9000 Series T6xx computer, perform the following steps: 1. Shut down the operating system and turn power off to the computer. (See page 15.) 2. Wear a grounding wrist strap that is connected to the HP-HSC I/O bus converter bulkhead. 3. Remove the HP-I-NC J/O bus converter from the computer. Refer to the computer system manual for instructions. 4. Grasp the SCSI adapter by its edges or faceplate.
Remove the cover blank from the slot where the SCSI adapter is to be mounted. See figure 8. To remove the cover blank, remove the two screws holding the blank in place. The screws are spring loaded. Apply slight upward pressure to prevent the screw from separating from the spring. 5. Figure 8.
6. Figure Install the SCSI card in the HP-HSC converter by pressing the card against the bulkhead of the HP-HSC converter. Seefigure 9. 9.
7. Before you push the connector on the SCSI card into the mating connector on the I-EHSC bus converter, turn the captive screws on the HP-HSC bus converter until they engage the SCSI card, but do not tighten the screws. 8. Align the connectors, then press them together securely. 9. Tighten the HP-HSC bulkhead screws to secure the SCSI adapter to the HP-HSC I/O bus converter. 10. Re-install the HP-HSC I/O bus converter in the computer system.
Connect Cable and Peripheral Devices With the adapter installed in the computer, you can now connect the adapter cable and the peripheral devices. SCSI Cable Connection Attach the SCSI cable to the adapter as follows: 1. Inspect the connector pins to be sure they are straight. 2. Carefully plug the cable connector into the SCSI adapter receptacle on the computer system. See figure 10.
Figure 10.
Peripheral Device Connections When connecting SCSI devices, follow these guidelines: Verify the host computer system is shut down. There should be no data transfer activity on the SCSI bus. Verify power is off to the peripheral device before connecting it to the SCSI bus. Check whether your devices contain internal SCSI bus terminators or require special terminates. If so, refer to your device manuals for instructions on how to prevent excessive or improper SCSI bus termination.
Terminate the SCSI Bus Unless the SCSI bus is properly terminated, the bus will not operate properly. Terminators provide matching impedance on SCSI bus signal lines. This product includes an external SCSI bus terminator to terminate the peripheral end of a differential SCSI bus. The terminator consists of a 68-pin, high density male connector with thumb screws. Install the external terminator on the end of the SCSI bus (opposite the SCSI host adapter).
Switch Power on to Peripherals, Computer then to the Before applying power to your system, follow these guidelines: 1. Verify all cables are connected and securely fastened. 2. Switch power on to your peripheral devices and wait for them to become ready before you switch power on to your computer. 3. Switch power on for your computer. When the computer’s power is switched on, power is supplied to the SCSI adapter. The SCSI adapter supplies termination power to the SCSI bus.
Configure the Operating System and the Adapter The HP-HSC Fast/Wide Differential SCSI adapter should au&xonfigure into supported HP-UX systems. When the operating system reboots it will determine your adapter has been installed and will install the correct software device files necessary for the operating system to communicate with peripherals connected to the adapter. Verm Operation The only indication of proper operation on the adapter is the green TERM POWER LED located on the adapter bulkhead.

Field Replaceable Units F’ield replaceable units (FRUs) are assemblies or components that are authorized for field replacement. Replaceable FlXJs on the HSC Fast/Wide Differential SCSI adapter: Description Part Number 125V, 2A, LF Fuse 2110-0517 Termination resistors (Removed only during the installation procedure in a multi-jnitiator situation.) 1810-1418 Exchange Assembly The adapter may be replaced under the HP exchange program.
Troubleshooting Tools Troubleshooting tools are used to identify faulty adapters. For this product, the following tools are available: n Term Power LED n Off-line diagnostics Term Power LED The termination power (Term Power) LED is green and indicates the adapter is supplying termination power to the SCSI bus. During proper operation, this LED is on. If the Term Power LED is off, this adapter is not supplying power to the SCSI bus.
Replacing the Term Power Fuse To remove and replace the Term Power fuse (F3), proceed as follows: 1. Remove the SCSI adapter from the computer. See the removal instructions on page 42. 2. Pull the fuse out of its socket. The location of the fuse on the SCSI adapter is shown in figure 11. Visually verify if the fuse is open, or by using a continuity tester. Fuse F3 Figure 11.
3. To install the replacement fuse, carefully align the two contact pins with the socket holes. Then press the fuse in (refer to figure 12). The fuse has no polarity, so the pins can go into either socket hole. SCSI Adapter Contact Pins Fuse part number 21100517 Fuse Socket Figure 12.
Off-Line Diagnostics The Off-Line Diagnostic Environment (ODE) is used to test to the I/O adapter level in the computer system. IOTESl’ and MAPPER are modules of ODE that check the functionality of the I/O modules in the computer system. ODE is run from the Initial System Loader (EL) on the system console. MAPPER ODE> mapper MAPPER>run The MAPPER utility provides the following hardware information: 1. 2. 3. 4. 5. 6.
IOTEST ODE> iotest IOTEST> run The IOTEWs strategy is to systematically check the basic functionality of I/O modules in the system. This is accomplished by either making a PDC-IODC call to invoke selftest, or by running a test within the diagnostic. IOTESl’ doesn’t test the functionality of devices. IOTESl’ is currently divided into 23 sections. Each section performs basic tests on a particular module. Note No on-line diagnostics are available for the HP-HSC SCSI adapter.
Removal/Replacement Instructions Removal of the SCSI adapter is the opposite of installation. Follow the instructions presented here and refer to the installation procedures on page 20. The adapter contains electronic components that can be damaged by static electricity. To avoid damage, follow these guidelines: CAUTION Store adapters in their conductive plastic bags. H If possible, work in a static-free area. n n Handle adaptersonly by the edges.
