This note is from an field engineer that has a problem
with the early version of TLZ07-BA. He has ordered
three new TLZ07-BAs and has not been able to get
them to work on the AS1000 running VMS 6.2.

Subj: tlz07 revised rev a5
ED,
In revisiting this Tlz07 adventure it appears that on the revised rev
a5, unless you have a remote scsi id switch all the drive setuo is
dome using the dip pack on the bottom of the drive. In this case I was
reconfiguring the jumper pack after having removed the customers rev a2
by the setting on the rev a2 dip switch. Wrong thing to do .
So my question is this if the revised version a5 comes factory
configured
with pins 15,16 Termination power jumper-on enabled. Do i need to
disable
it ?
The rest of the jumpers are as follows. 1-6=off disabled
11-12=off disabled
15-16
=on enabled
The EK-tlz07-om manual pages 3-4 thru 3-6 dont address jumper 15-16 in
a replacement mode. The system is an Alphaserver 1000 single bus with
active termination at end of the bus. Any thoughts
Regards Greg Feinberg

I have not been able to come up with the information.
Any ideas?

It must be my Dutch, which causes me problems understanding the real
issue, except the Term Power:
The TLZ07-BA (as they come in) have the Term Power Jumper IN (and
it's the only jumper installed) for the newer-style Rev A5.
I have replaced several TLZ07-BA's in AS1000's lately (all A5's)
I and just left the Term Power jumper in. But with the jumper
removed, it must still work, because the SCSI-port in the AS1000
delivers Term Power for the far-end terminators.
For the Rev A5's in a AS1000, The SCSI-ID's can be set by the switches
OR the jumpers (it's wired-OR'd). Default: Leave the ID-jumpers out
and use the switches for ID-setting. (all this is labeled on the
drive).
Not sure about the statement 'that it did not work'.
WHAT did not work?
