AW: Twinax printer IBM 6412 IPDS on V4.5

Hello,

we also had problems with Twinax/IPDS printers after upgrading from 620 to
820. In the problem
determination process we found, that IBM has changed/enhanced the twinax
protocol - look for
APAR II11804. You can switch back to old protocol with a dataarea.

We have a similar config, i.e. fiber optics over multiplexor to warehouse,
and finally found that
we had mixed ports from 2 controllers on the same multiplexor.

Are your failing printers on the same port? If one device on a port fails,
it can affect all others.

I would also check the multiplexors - try different connections etc. Every
now and then we have
problems with these biests.

Good luck,

Oliver Wenzel
