Troubleshooting 

 

If you install an Ultra Narrow SCSI HardTape Bay and it does not function 
properly, please follow the troubleshooting steps below. 
 

Step 1.  Check Host Adapter 

Verify the adapter card is seated in its slot on the motherboard. 
 

Step 2.  Check all Connectors and Cables. 

Check to ensure Bay PCB power connector, internal SCSI connector and ribbon 
cable connectors are properly seated.  Ribbon cables are easily damaged due to 
improper folding.  Replace a damaged or suspect cable with a known good  
cable.  Make sure no connector pins are bent.  Verify pin-1 on the interface  
cable is aligned with pin-1 on the drive and host adapter. 
 

Step 3.  Verify the Jumper Setting. 

Review the section “Configuring your Ultra Narrow SCSI HardTape Bay to 
check if the jumper setting is correct. 
 

Step 4.  SCSI ID Conflict. 

If you have multiple SCSI devices, please make sure that no ID numbers are 
duplicated.  To reduce the chance the ID switch will malfunction, test each 
SCSI device individually. 
 

Step 5.  Poor External Cable Problems. 

Weak electrical grounding may occur if many SCSI devices are daisy chained 
and some of the external cables are not “high density” 50-pin cables.  For    
example, if you are daisy chaining many SCSI devices to MAC through 50-pin 
SCSI cables and you have intermittent failures, it is recommended that you  
replace this cable with a better quality cable.
