DISK DRIVE ST34520W
Mounting and Option Information
There is a new hard drive, SEAGATE ST34520W-4 - Com Code 407 942 135. The MLO's are sending this
drive as the replacement for the ST52160N.
This drive is a wide SCSI drive. To use it in a DEFAUD or an R1 you need the SCSI adapter for it
- Com Code 407 846 245.
The drive is used now in the AUDIX SLIM. To use it on a DEAUD with the adapter, the hard
drive needs to be spaced out from the drive bracket to clear the parts on the TN2169 behind the hard drive,
even then it will be a tight fit.
Use MOTOR START and PARITY and SCSI ID of 0 for DEFAUD. SCSI ID is needed for the R1
AUDIX, terminator disable is required.
-Joseph Berger
2/23/99
It is recommended that the Shielded SCSI Cable - Com Code 601 866 163 - be used with this disk drive
because it is shorter and more flexible.
Information from Wayne Motycka (2/24/99) and www.seagate.com :
DEFINITY AUDIX needs no option straps, but R1 AUDIX does.

Required air gap between Circuit Board components and SCSI
Cable adapter and connector, this gap wil be extremely small, this picture shows a considerable gap
that overstates the space. The tech will need to assure that he can see light under the adapter.

Differential
New SCSI designs will use drives with the Ultra2 SCSI Ultra2
low-voltage differential (LVD) doubles Wide SCSI bus data rates to
80 Mbytes/sec, increases bus cable lengths to 12 meters, and
provides the capability to add up to 15 peripherals on the bus Ultra2
SCSI is backward-compatible to previous versions of SCSI
