Ultra Wide SCSI-3 Bus
 
Ultra Wide SCSI support is offered on the Power Macintosh 
G3 Minitower (optional feature) and G3 Server (standard 
feature) via an Ultra Wide SCSI PCI card (p/n 661-2011). 
If present, this card is installed in the first PCI slot on the 
logic board. You can connect a total of three internal devices 
to the Ultra Wide SCSI-3 bus.
 
Important
 
: Before you connect an internal device to the Ultra 
Wide SCSI-3 bus, refer to the information on cable length 
limits and termination later in this section. 
The following illustration shows where to install SCSI 
devices for use with the Ultra Wide SCSI-3 bus and how to 
route the Ultra Wide cable. (Note: More detailed information 
on how to route and tape the Ultra Wide SCSI cable can be 
found in the Take-Apart chapter in the Hard Drive topic.)
