About This Guide ix Table 1 (Cont.
1 Testing This chapter is an overview of the testing procedures for the VAXstation 3100 model 38 and 48 systems. Since the testing procedures for the VAXstation 3100 models 38 and 48 are similar to the testing procedures for the VAXstation 3100 models, this chapter will not repeat the information described in Chapter 1 of the VAXstation 3100 Maintenance Guide.
2 Testing 1.1 Running Power-Up Tests Power-up tests run each time you turn the system power on and, if the tests are successful, the operating system starts booting. Power-up testing consists of a sequence of tests executed for each device installed in the system. The test number of each device is listed on the power-up screen display as the device is tested. To run power-up tests, turn the system power switch on. Example 1–1 shows an example of the power-up screen display. KA42-B V1.0 F...E...D...C...B...
Testing 3 Table 1–1 lists the test numbers and the devices that are tested during that particular test. To look at the status of a device, display the configuration table. >>> TEST 50 The configuration table lists every device in the system and also lists the results of the power-up tests and self-test. It is updated each time a self-test is run (mouse status is not updated).
4 Testing Table 1–1 (Cont.) Power-Up and Self-Test Commands Test Mnemonics Device T3 Option module (not available) T2 Option module (not available) T1 NI Ethernet circuits Example 1–3 shows an example of the configuration table. >>> TEST 50 KA42-B V1.0 ID 08-00-2B-02-CF-A4 MONO 0000.0001 CLK 0000.0001 NVR 0000.0001 DZ 0000.0001 00000001 00000001 MEM 0008.0001 00800000 MM 0000.0001 FP 0000.0001 IT 0000.0001 SCSI-A 0808.0001 FFFFFF05 FFFFFF05 SCSI-B 3C3C.0001 FFFFFF05 FFFFFF05 SYS 0000.
Testing 5 1.2 Running a Self-Test Self-test allows you to test every device again after power-up tests are complete. Devices can be tested individually (except for drives), a few at a time, or all of them sequentially just like power-up tests. To individually test a device (drives are tested all together on their particular bus), enter the word (TEST) or just the letter (T), followed by a space and the test number of the device you want tested.
6 Testing 1.2.2 Self-Test Codes If an error is detected during a self-test, a question mark (?) is put next to the test number and a failure message (84 FAIL) is displayed. You must display the configuration table (enter TEST 50) after a self-test is complete to see the error code. 1.3 Running System Exerciser Diagnostics The system exerciser simulates a worst-case operating system situation test for each device and checks how the device operates under these conditions.
Testing 7 1.3.1 System Exerciser Diagnostic Commands Table 1–2 lists the system exerciser diagnostic commands. When running TEST 0 or TEST 101, the exerciser automatically stops after about 5 minutes and the halt message (06 HLT INST) is displayed. This halt message is normal for these two tests. Table 1–2 System Exerciser Diagnostic Commands Test Description of Commands T0 Runs customer mode system exerciser. No loopback connectors are needed.
8 Testing 1.3.2 System Exerciser Codes The system exerciser displays the status of the devices on the screen as the exerciser is running. Any errors found are displayed in the exerciser display. When examining the exerciser display, a question mark (?) in the far left column indicates a soft error, double question marks (??) indicate a hard error, and the absence of question marks usually indicates success.
2 Troubleshooting This chapter contains information for troubleshooting the new devices available on the VAXstation 3100 model 38 and 48 systems. The label on the back of the system box indicates which model you are working on. The WS42A-xx model number on the label identifies model 38 and the WS42B-xx model number identifies model 48 systems. All procedures in this chapter apply to both system models unless specifically listed in the section titles or as described in the text.
10 Troubleshooting The diagnostics used to test the 8 Mbyte memory module tests all of the main memory in the system including the 4 megabytes on the system module. Therefore, any error for the memory must be deciphered to determine which module contains the error. There may be more than one module containing the error. Running a Self-Test A self-test performs a quick checksum of the memory in the system. The results are stored in the configuration table (T 50). To run a self test: 1. Enter TEST B. 2.

To determine which device is faulty, examine the status codes of the individual drives.
Troubleshooting 15 2.3.1 Running the System Exerciser The system exerciser performs a more thorough test of the RX23 diskette and the SCSI adapter module. It performs a read/write operation during the second pass of the exerciser when the special keyed diskette is loaded in the RX23 drive before starting the system exerciser. To run the system exerciser: 1. Install a loopback on the communication port. 2. Load the special keyed diskette in the RX23 drive.
16 Troubleshooting If an Error is Detected If there are any question marks (?) on the SCSI controller’s status line, the SCSI controller is probably faulty and must be replaced. If there are any question marks on a drive’s status line, the problem could be in either the drive, the SCSI bus cabling, the SCSI bus terminator, or the SCSI controller.
3 Utilities (T 74 and T 76) This chapter describes the two new utilities available on the VAXstation 3100 models 38 and 48 systems. These two utilities are both used to format RX23 diskettes. Test 74 formats the special diagnostic key on the test diskette, which allows the field service system exerciser to perform writes to the drive. Test 76 formats new diskettes for normal data storage. Table 3–1 lists all of the utilities available on the VAXstation 3100 models 38 and 48 systems.

6 RZ56 Storage Expansion Box This chapter describes the RZ56 storage expansion box. The RZ56 disk drive is stored in the BA42 enclosure as shown in (Figure 6–1). MA-X0563-89 Figure 6–1 BA42 Enclosure with One or Two RZ56 Disk Drives For additional information on the RZ56 drive, refer to the RZ56 Disk Drive Service Manual (EK-RZ56D-SV).
RZ56 Storage Expansion Box 55 6.1 General SCSI Bus Configuration Information The following is general information on the SCSI bus: • The external SCSI port on the back of the system box can be connected with one to six drives. However, system performance is slower when more than four drives are connected. • The BA42 enclosure storage expansion box can contain one or two drives. Make sure you configure the second drive’s SCSI ID if the box contains a second drive.
56 RZ56 Storage Expansion Box (Figure 6-2) shows how the BA42 storage expansion box connects to the system box.
RZ56 Storage Expansion Box 57 (Figure 6-3) shows how the BA42 storage expansion box connects to the system box. SC SI TERMIN ATOR TO SYSTEM BOX MA-X0960-89 Figure 6–3 BA42 Enclosure Daisy-Chained 6.3 Troubleshooting the BA42 Enclosure To troubleshoot the RZ56 disk in the BA42 storage expansion box, use the self-test and system exerciser diagnostics in the system box. Self-Test Results The following table lists the normal self-test results for the RZ56 disk drive.
58 RZ56 Storage Expansion Box Code Description 00000001 Good results. There is no error for the drive located at the SCSI address ID. The SCSI ID is set by depressing the switches on the back of the storage expansion box (should be ID 0 and/or ID 1).
