1. Introduction
This 53c700 SCSI adapter firm ware is for supporting greater than 8 luns and iNCReases the
maximum up to 16 luns.
The NCR3450 manufacturing incorporation was:
Tracer no. 36-008700 s/no 36-25811221.
2. Method of change
The method for change will be to modify P.C.B.'S as they pass through repairs or production.
It will also be necessary to modify SCSI adapters when upgrading an unmodified system
above 8 luns.
The customer services
supervisor is to contact technical services for implementation instructions.
3. Change
3.1. note: full esd precautionary procedures must be followed at all times.
3.2. ensure the customer has two verified file saves.
3.3. have the user perform the necessary procedures to shut down the system in an orderly manner.
3.4. before attempting to modify the
SCSI adapter the current firmware revision level must be determined.
If it is 1.2.0.0. Or
higher then the SCSI adapter does not require to be modified.
There are two methods of determining the revision level:
* physical inspection - see paragraph 3.9.
* SCSI inquiry - see paragraph 3.5.
(tech serv ref 11/10/1)
(cssb 95-0100)
3.5. SCSI inquiry
Before powering off use the system for SCSI inquiry:
* bring up the sus menu.
* select (4) extended diag services.
* select (1) SCSI diagnostics.
* select (6) SCSI expansion rom revision
This will display the firmware revision for each SCSI controller in the format xxxx where
a (.) Is
assumed between each x.
Make a note of the firmware revision level displayed. If the revision level is
1.2.0.0. Or higher, the
SCSI adapter does not need modifying.
3.6. power off the system. Open both
the ac mains and the battery circuit breakers located at the rear of the
unit.
3.7. locate all the dual SCSI controller boards and note which board is in which microchannel slot.
3.8. remove all the SCSI controller boards from the unit and note the serial number and part number of each.
3.9. physical inspection
Examine boards for the following part numbers:
530-0034306 530-0034774 530-0035437 EPROM location 6j
530-0034307 530-0034775 530-0035438 EPROM location 6j
530-0034308 530-0034776 530-0035439 EPROM location 4e
530-0035440 EPROM location 6j
530-0035631 EPROM location 4e
530-0035643 EPROM location 6j
Boards with part numbers higher than those listed above may be re-installed in the system
immediately.
Firmware on all boards
matching the numbers listed above must be examined.
3.10. locate EPROM in location 6j or 4e as applicable,
if the part number of the EPROM is not 530-0018579
it must be replaced
with the EPROM provided in retrofit kit number 603-5013227. Note: only the last
four digits of the part
number are written on the ic chip.
3.11. re-install the SCSI controller boards in their
original locations. It is important that the system
configuration remains
the same as it was before the upgrade unless it is being reconfigured on
purpose. The system
will report errors whenever a module is moved to a different slot.
3.12. power up the system.
3.13. reboot the system and check for any level 0 reported errors.
3.14. note: if appropriate, upgrade the system firmware provided
(2.00.02.2). It will also be necessary to run the reference diskette. Refer to system
hardware
documentation and
transmittal documents provided in the kit.
4. Testing
Check for the ability to access all SCSI devices connected to the upgraded controllers.
5. Recording action
Attach a modification label to the SCSI adapter, if not already fitted, strike through but
do not
obliterate 3.
Complete all other relevant documentation.
