Important Facts for the VAXstation 4000 Customer

This errata sheet contains important information on the following topics:	

· SCSI IDs for devices on the TURBOchannel PMAZ option	

· TURBOchannel support on the Model 60 and Model 90	

· Video connector RFI gasket installation	

· SPXgt graphics module removal	

SCSI IDs for TURBOchannel PMAZ	

Use SCSI ID 0, 1, 2, 3, 4 or 5 for your devices on the TURBOchannel PMAZ	
option; do not use SCSI ID 6 or 7. On the VMS operating system, SCSI ID 6	
is reserved for the controller, and on the UNIX operating system, where the	
PMAZ option originates, SCSI ID 7 is reserved for the controller.	

TURBOchannel Support	

The VAXstation 4000 Model 90 fully supports both programmable I/O (such as	
Ethernet and SCSI) and DMA (such as FDDI) devices on the TURBOchannel	
Adapter.	

The VAXstation 4000 Model 60 supports only programmable I/O (not DMA).	

Video Connector RFI Gasket	

When you install a graphics module, be sure that the RFI gasket is flush	
against the video connector. Your graphics module may appear to be installed	
correctly, but if the RFI gasket is not flush with the video connector, it will not	
meet FCC regulations.

SPXgt Graphics Module Plastic Standoff	

Use the plastic standoff shown in Figure 1 as a pulling device when you lift	
the SPXgt frame buffer from the center connector to avoid damage caused by	
pulling up on the tail bracket.
