Firts, note the labels on the PROM. The label is broken down into three parts. The first two characters represent their position on the PCBA. The middle character is the model number. The last character is the revision level of the program contained within the PROM. Example: A1-1.5 A1 This PROM goes into position A1 of the PCBA -1 This UPTIME board is a Model 001 .5 The PROM contains the 5th revision of the programfor this model If the PROM labels are not legible, the model can be identified by th serial number as shown in the chart below: PROM SERAL MODEL LABEL NUMBER ----------------------------------------- 001 A1-1.5 10000 to 11999 002 A1-2.2 12000 to 13999 003 A1-3.6 14000 to 16999 004 A1-4.0 20000 to 29999 *** AVAILABLE DOCUMENTATION *** UPTIME On Site Diagnostic Reference Card S-HDBK-243 UPTIME OPERATOR'S GUIDE ----------------------------------- Model 001................S-HDBK-230 Model 002................S-HDBK-232 Model 003 & 004..........S-HDBK-233 *** AVAILABLE TRAINING *** VIDIO TAPE M1566 *** SPECIAL ADMINISTRATIVE PROCEEDURES *** At installation time, the installing F.E. must obtain customer signature on a service contract addendum which states the UPTIME is the property of NACS and that the UPTIME will be surrendered to NACS upon termination of the service contract. DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB001 Pg001 After installation of the UPTIME is complete and checked out, place the jumper cable removed from the CPU set inside the CPU cabinet. This is the property of the customer and will be replaced upon termination of the service contract. UPTIMEs are capital expenditure items. Each one has a serial number etched in the PCBA. If a unit goes defective and must be replaced, update the customer contract addendum mentioned above. Then the defective unit must be returned to KOP for repair, using a Fixed Asset Movement Notice form. ORIGINATOR: J. ROGERS DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB001 Pg002 FIB 00002 02/26/81 *** UPTIME runs but outputs only to the parallel printer(s) *** SYMPTOMS: System will not load BOSS but run light comes on UPTIME runs but outputs only to the parallel printer(s) FIX: These two symptoms can be caused by ANY of the following: 1. The -16.75 volts missing 2. The one and only 8-way defective on a 510-730 system 3. The ACCESSORY PCB defective on a 200-410 system ORIGINATOR: M. NUNAN DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB002 Pg001 FIB 00003 02/26/81 *** Explanation of Memorex fault light during UPTIME run *** The fault light on the B/4 Interface PCBA may come on at three different times while running the UPTIME diagnostics. 1. The fault light will come on after the drive status test. This happens when the UPTIME is testing the drive to find out how many heads are physically on the drive. If the drive only has four or eight heads, the fault light will come on during this test. 2. When running the "E" utility, UPTIME will try to read from all 12 heads on each of the first four cylinders. If there are only four or eight heads on the drive, the fault light will come on when UPTIME trys to read from the non-existant heads. 3. When running the "C" utility, if you select a head less than 12 ( C in HEX ) and that head does not exist, UPTIME will try to read from that head and the fault light will come on. ORIGINATOR: M. NUNAN DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB003 Pg001 FIB 00004 02/26/81 *** Canned diagnostics loop back to start before completed *** This problem may be caused by a slow memory board. It will normally follow the slow board. This will help in locating the failing, slow board. It has also been found, in some cases, that a bad board may cause ALL of memory to fail in this manner. If this is the case, it may be necessary to run UPTIME with only one memory board at a time until the failing board is located. The problem that the customer may be experiencing is that the system may intermittantly hang in a RUN or go into a HALT. The looping problem has been caused by a defective ACCESSORY or CPU board. ORIGINATOR: M. NUNAN DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB004 Pg001 FIB 00005 02/26/81 *** UPTIME does NOT check the memory parity bit *** UPTIME does NOT check the memory parity bit during any of the diagnostics. If this bit if failing, the UPTIME will not detect it! The memory test in the Babysitter and memory test in the utilities are both different from the memory test in the Canned routines. All of these tests should be run when looking for a failure on the system. ORIGINATOR: M. NUNAN DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB005 Pg001 FIB 00006 06/23/81 *** Damage to fixed disk systems when installing UPTIME *** Caution should be used when installing an UPTIME board on fixed disk systems that have VDT cables with grounding straps. These straps can touch the back of the UPTIME board and ground out +15 volts. ORIGINATOR: D. WOODWARD DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB006 Pg001 FIB 00007 09/23/81 *** UPTIME shows false disk failures on 510, 610, & 730 systems *** Basic Four is presently shipping Adapter Buss PCB's P/N MM820050, with a revision level of "N". These "N" level PCB's have ECN 7126 installed on them to correct error 07 problems. This ECN has also been installed in the field on some Adapter Buss boards. With this ECN installed, UPTIME will not preform the disc read properly. It will indicate a failure of all discs. IF YOU ENCOUNTER AN ADAPTER BUSS BELOW REVISION P - REPLACE IT IMMEDIATELY! ORIGINATOR: D. WOODWARD DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB007 Pg001 FIB 00008 10/01/81 *** UPTIME disk read failures may be caused by various controllers *** There have been instances where UPTIME has displayed "DRIVE 0 READ - FAILED" and the problem was not in the drive. The DMA board was causing the failure. This could be caused by the disc DMA, a tape DMA or a IMLC board. To help determine the cause of a disc read failure use the utilities to get the disc status. ORIGINATOR: D. GOEHRISCH DIAGNOSTICS-BASIC FOUR-LS UPTIME--------------------FIB008 Pg001 FIB 00009 12/05/85 *** Cautions for when UPTIME reports a disk failure *** PROBLEM: UPTIME may report a removeable disk drive as "FAILED" although the system is operating properly. FIX: UPTIME tests 4 cylinders of a drive for 1350 CPU and 64 cylinders for a non-High Speed CPU. Since UPTIME firmware constraints did not allow space to deal with alternate tracks, the display will report the drive as having failed UPTIME. This reported 'Failure' does not therefore indicate a real problem if an alternate track within the range of tested cylinders is encountered. Page 4 of the customer's UPTIME instruction book states that the FE "will determine if a hardware problem exists". Keep the above information in mind during this determination. ORIGINATOR: J.
