A03.04 and below. When running the printer test with a Printronix connected to a TDP board at Revision Level G, a bad status message 9016 is reported. There is no hardware problem and the error should be ignored. A later release of REMIDI will correct the false error reporting. ORIGINATOR: J. KANZLER DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB001 Pg001 FIB 00002 12/22/82 *** "DOCWRITER" introduction *** System 810 software release 8.1A and above contain the documentation necessary for using the diagnostics. It is suggested a copy be printed when the system is installed and kept on site. The name of the program to run is named "DOCWRITER" and is located in the ".INST." mode of the file system. An example of the complete file name would be ".R1K. INST.DOCWRITER". The program uses the line printer and the system spooler. ORIGINATOR: J. KANZLER DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB002 Pg001 FIB 00003 04/12/83 *** System 810 T-303 head alignment using DEMON MBF model 4502 *** GENERAL: 1. It is assumed the reader has prior experience with regard to aligning Trident series disk drives (consult service manual if necessary). 2. Appropriate CE pack for use on the T-303 is the equivalent of that used for 3330-II drives (part number 2200735 on the IBM tools list). 3. If it is not possible to load DEMON from disk, use a tape boot version. DEMON SET UP: * Alignment pack should be installed and heads loaded at this point in time. After obtaining the DISK TEST menu, enter a "Z" to set all test options for "O" iterations and proceed as follows: 1. Select test option one (Rezero/fault clear) and set for one iteration. 2. Select test option two (Seek) and set for one iteration. At this point you will be presented with a sub-menu, set each of its three options by selecting each letter. a. Start cylinder to 496 b. End cylinder to 496 c. Step (#,A,R) to 0 3. Once you return to the main test menu, enter a carriage return and then an "R" to run. * Do NOT "loop" on test, leave lower portion of main test menu in default settings. Looping on test will cause continuous rezeros. 4. Heads should now be sitting over cylinder 496, insert "grenade pin" and proceed with alignment process. HEAD SELECTION: Short to ground (i.e. pin 8 of referenced IC) the appropriate pin on the head decode IC as indicated below. This will enable the designated for reading its respective media surface. Even Numbered Heads: 7445 at location A4 on right hand Matrix PCB as seen from rear of unit.

LEIBOWITZ DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB003 Pg002 FIB 00004 06/14/83 *** Information on making DEMON boot tapes *** NOTE: Do not attempt to overwrite any 8.1 DEMON tapes with 8.2 as 8.2 is incomplete. The procedure to make a tape boot copy of DEMON will change with software release 8.3. A Message file is now required as part of the procedure to create a DEMON boot tape. Under normal circumstances, backing up the entire "OS3" node should result in a viable boot tape. This would be done as follows (SAVERESTORE; Save Files To Tape): .Rxx.INST.OS3. where xx = Release number The result should be: When an 810B file IS present: .Rxx.INST.OS3.ADxxxxxxxxxx .Rxx.INST.OS3.BDxxxxxxxxxx .Rxx.INST.OS3.MSG.FILE .Rxx.INST.OS3.UVxxxxxxxxxx When an 810B file IS NOT present: .Rxx.INST.OS3.ADxxxxxxxxxx .Rxx.INST.OS3.MSG .Rxx.INST.OS3.UVxxxxxxxxxx Where "AD" is loader/WCS for 810A tape image "BD" is loader/WCS for 810B tape image "MSG" is common DEMON tape O.S. "UV" is common DEMON disk O.S. image ORIGINATOR: I. LEIBOWITZ DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB004 Pg001 FIB 00005 09/23/83 *** Loopback cables for DEMON diagnostic are available *** The loopback cable described in the DEMON USER'S GUIDE for 8-way testing has been released as a manufactured item. The loopback cable (BFISD P/N 907475-001) has been assigned an ICN of MM899420. Eight of these cables (actually "plugs") are required to test the external loopback. Note that the internal loopback tests in DEMON will check all the way out to the UARTs by looping them internally. Using the external loopback (which requires the cables) allows for testing of the RS232 drivers. ORIGINATOR: I. LEIBOWITZ DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB005 Pg001 FIB 00006 09/23/83 *** DEMON shows erroneous 8-way failures on 810 System *** The DEMON Diagnostic versions 2.1.30.10 and below, when operating on the System 810, and testing PCBA 903383-001 (MM896040) exhibits false errors with respect to DEMONS "Timing" and "Baud Rate" tests. This is a false error condition and its results should not be used for replacing the PCBA. All other 8-Way tests operate correctly and their results can used for a pass or fail determination. When the same PCBA is tested in a Series 8000 using the same version of DEMON no false errors are reported. DEMON version 2.1.30.12 and above will correct this problem. This version should be on the 8.2B software release. ORIGINATOR: J. KANZLER DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB006 Pg001 FIB 00007 11/02/83 *** REMIDI module numbers may not be the same for 8000 as for 810 *** Note that test module numbers for a particular test may NOT be the same for REMIDI on the 810 versus REMIDI on the Series 8000. Additionally, new releases of REMIDI (all diagnostics for that matter) are made to (1) add an enhancement (such as the forthcoming byte mode test) or (2) a code change to correct a problem. For these reasons, the service person should check the revision history for REMIDI (or any other diagnostic) via the "DOCWRITER" program and run a new user's guide if necessary. ORIGINATOR: I. LEIBOWITZ DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB007 Pg001 FIB 00008 09/07/84 *** Information on DEMON boot tapes for Release 8.4B *** Software level 8.4B adds the ability to test shared memory controllers when DEMON is brought in from tape. The boot tape must contain the "TZ80" files which are the Z80 code files for the various controllers. "FILE 1" Contains the 8 WAY code "FILE 2" contains the IMLC code "FILE 3" contains the 4 WAY code "FILE 4" contains the 16 WAY code As usual, a boot tape can be made by backing up the whole "OS3" node (i.e. ".R4B32.INST.OS3."), the following file list should result: .R4B32.INST.OS3.AD040228010 .R4B32.INST.OS3.BDO40228010 .R4B32.INST.OS3.MSG.FILE .R4B32.INST.OS3.TZ80.FILE1 .R4B32.INST.OS3.TZ80.FILE2 .R4B32.INST.OS3.TZ80.FILE3 .R4B32.INST.OS3.TZ80.FILE4 .R4B32.INST.OS3.UV040228010 ORIGINATOR: I.

Demon reports: STATUS EXPECTED BUT NOT RECEIVED: HIGH SPEED SOLUTION: This intermittent error results from an erroneous status being reported by the Cipher drive and should be ignored for test purposes. ORIGINATOR: J. RIPPL DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB009 Pg001 FIB 00010 01/02/86 *** REMIDI for 7000/8000 - 8.5 Releases *** In the 8.5 OS levels REMIDI now has two versions. The REMIDI.BVxxx version includes all micro-diagnostics prior to the introduction of the MPC controller. The REMIDI.BMVxxx version in the 8.5A and 8.5B releases contain only the MPC controller micro-diagnostics. In the 8.5C and later releases the BMVxxx version is called BVMxxx. (x's relate to release levels). Since REMIDI is a WCS Image, two WCS slots will be required. The extra slot will be provided using the DEMON WCS slot. For the two versions to be accessed, updating the load directory (UPDATE.LD) will be required to set DEMON to use OS 3 and WCS 0. DEMON WCS is the same as the Operating System WCS in slot 0 or 1. UPDATE.LD will also be required to select one of the two versions of REMIDI since only one can run at a time. If you have a MPX 7000 System the following steps must be taken: NOTE: Lines preceded by an "*" require operator input. 1. Install the REMIDI BMVxxx version WCS in slot 3 with UPDATE.WCS. * Input in command mode !UPDATE.WCS Update.WCS 8.5xx.x * ENTER WCS Slot (0..3) :3 Available disk units are :0,1 * Disk to update :0 * WCS image file (=first found) :.R5xxx.INST.REMIDI.BMVxxx (or BVMxxx) Updating Disk unit 16 sector ___ WCS update completed ! NOTE: 1. The revision levels of the software modules are represented by an "x". 2. the level of the WCS IMAGE file must be known. this level is also the operating software level. i.e., .R5A28. .R5B30. 2. Update the Load Directory for DEMON by using the UPDATE.LD utility. * Input in command mode !UPDATE.LD Update Load Directory Utility 8.5xxx.xx Disks (Unit number) on line: 0(16),1(17) * Enter disk number 0 Load OS/WCS I OS Level Name WCS-Level 0 0/0 I 5.x.x.x R 85xxxx (date) B 5.x.x 1 1/1 I 5.x.x.x R 85xxxx (date) B 5.x.x 2 0/2 I B 5.x.x R 3 3/3 I 5.x.x.x DEMON (date) B 5.x.x R * New OS slot (0,1,3):3 * New WCS slot (0..3):0 * Load sector (0..3) :3 Load OS/WCS I OS Level Name WCS Level 0 0/0 I 5.x.x.x R 85xxxx (date) B 5.x.x 1 1/1 I 5.x.x.x R 85xxxx (date) B 5.x.x 2 0/2 I B 5.x.x R 3 3/0 I 5.x.x.x DEMON (date) B 5.x.x R NOTE: 1. The revision level of the software is represented by an "x". 2. Notice the change in load directory it went from 3/3 to 3/0. It was using WCS SLOT 3, it is now using WCS SLOT 0. DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB010 Pg001 Only one version of REMIDI will run at a time. The version that will run is dependent on how the Load Directory for REMIDI (Load Directory #2) is set up. - The standard version BVxxx which resides in WCS slot 2 has an OS/WCS of 0/2. - The MPC version BMVxxx will only run once the Load Directory has been updated. with UPDATE.LD to change the OS/WCS to 0/3. Follow step 2 to accomplish the update of the Load Directory using the following: * New OS slot (0,1,3): 0 * New WCS slot (0..3): 3 * Load sector (0..3): 2 To go back to the standard version of BVxxx, in UPDATE.LD use: * New OS slot (0,1,3): 0 * New WCS slot (0..3): 2 * Load sector (0..3): 2 Refer to .INST.DOCWRITER for added information on REMIDI/MPC diagnostics.

LUQUE DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB010 Pg002 FIB 00011 10/01/86 *** 9000 REMIDI test for 2,10,X,X four-tuple problems *** A test was added to REMIDI to help detect the cause of 2,10,X,X dumps. This test will set up a special timing sequence to test the 869 IC on the ESTK board. The 869 IC is an 8 bit synchronous counter which makes up part of the memory address registers. This IC was found to occasionally fail at low margins. When running this test, the system should be set to low voltage margin. When REMIDI has completed return the system to normal voltage margin. The error codes for this test are 6C01, 6C02, 6C03, which would indicate a component failure on this ESTK board. This test will be added to the 9.6A REMIDI. Copies of this version of REMIDI will run on any 9.5 level and will be supplied upon request. For further information on REMIDI, please refer to DOCWRITER under the INST node. ORIGINATOR: LEO SANDERS DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB011 Pg001 FIB 00012 01/04/88 *** REMIDI failure on DMA when running all tests (9.6 OS) *** SYMPTOM: When running all tests (all sense switches off during wait message) on 9.6 OS REMIDI. The diagnostic shows a failure on DMA board #7. I have seen this failure on two 95X0 systems. One of the two systems had two DMA boards, and the other only had one DMA board. If the DMA section or controller tests are selected individually from REMIDI (front pannel selection), the DMA test runs OK. FIX: Select DMA tests individually from front panel switches to see if you have a DMA problem. ORIGINATOR: Allan Mollyhorn DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB012 Pg001 FIB 00013 10/25/88 *** ASxx Diag. Notes now in Docwriter Diag. Notes [ WPSF 495 ] *** A new section has been added to the DOCWRITER document, "Diagnostic Notes and Cautions". This section includes information pertaining to possible problems that may be encountered during system tests. Though this Field Bulletin is directed towards the Advanced Series Family, the "Diagnostic Notes and Cautions" will also contain information for the MPx Series Systems. A brief description of the Advanced Series notes is as follows: o FREQUENCY MARGINS The Advanced Series processor has the capability to run diagnostics at a faster clock rate. This is achieved via the 'Clock Frequency Margin' switch, SW3-4 located on the MCS/M PCBA. This option should NEVER be used concurrently with Voltage Margins. It will result in failures which ARE NOT due to bad hardware. NEVER leave the customer site with this switch set to 'ON'. The customer is NOT to operate in this condition. o LAN PCBA The LAN PCBA self-test may fail with the Clock Frequency Margin. This will result in the LAN PCBA's failure to check in with the Operating System at boot time. This will prevent testing of the LAN PCBA in the Type 1 Load using NEWX. DEMON testing of the LAN PCBA will be affected too with Frequency Margin. The tests affected are the UART counter/timer tests which use the system clock to time operations to specific tolerances. When the Clock Margin is set, DEMON will skip the applicable tests. o 16 WAY PCBA DEMON local loopback tests fail with the Frequency Margin. When DEMON detects the higher frequency clock, these tests will be omitted. o DMA-I PCBA REMIDI test for the NEP-II PCBA, used in the Advanced Series family, forces a "bus error". This causes the amber Memory Timeout LED, DS2, to turn on. Revision "T" DMA-I PCBA will prevent this from occurring. o OTHER NOTES NOT IN DOCWRITERS' "NOTES AND CAUTIONS" The MBA PCBA MMC Read Data Parity Error LED, DS3, may come ON during the first pass of REMIDI. This condition only occurs when the system is brought up from a "Cold Start/Power On" condition (Mainframe ACDU's turned ON from an Off state and the system powered ON). REMIDI test in the 3600 range reads a register that is in an unknown state from Cold Start condition, thus generating a Parity Error when read. After this test the register is written to, putting it into a known valid state. After manually resetting the LED by the Reset LED switch, consecutive passes will not fail. This problem will be fixed in a future release of REMIDI. DIAGNOSTICS-BASIC FOUR-810, MPX & ASxx SYSTEMS------FIB013 Pg001 Clock Frequency Margin message "WARNING: SYSTEM IS RUNNING AT CLOCK MARGIN" is displayed erroneously without the correct Software/Hardware combination. If the MCS/M PCBA is Rev "F" or below and the system OS is 10.6E*11 or above, this message will display when it's NOT in the CLOCK MARGIN state and won't display when it is. Clock Margin is active when SW3-4 = 0 (Closed/On) on the MCS/M. Revision "G" and above MCS/M with 10.6E*11 and above will display this setting correctly. When in doubt, check the switch setting on the MCS/M. ORIGINATOR: D.
