SCSI Problems on Repaired Flyers
Product: Flyer
Platforms: 2000 3000 3000T 4000 4000T
PROBLEM: Flyer card exhibits problems with the SCSI bus on one or more ports after returning from Repair.
On those occasions when repairs are done on Flyer cards to components which may be near the SCSI port (there is a particular clock buffer chip repair that often affects this), flux may splatter into the SCSI sockets. The Repair technicians make every effort to get this cleaned before sending the card out, but sometimes miss some. If a repaired card shows SCSI problems, we recommend the user or the user's service technician check for flux traces among the SCSI header pins, and clean as follows:
Use Flux-Off first (1692 Chemtronics is what we use in our shop), then follow with Caig Laboratories DeOxit D-5. DeOxit is also good to use for cleaning the Zorro edge. When the Zorro edge is not clean, Flyer will show unreliable operation, and lack of contact on one of the lines on the Zorro bus can cause intermittent resets.
