Re: Ethernet vary off/on - no twinax

["Pete Massiello" <pmassiello-ml@xxxxxxxxxxxx>]

Lets make sure we say Power 6 520's, as they can not have IOPs in the CEC,
which causes you to not be able to have a Twinax console (or any other
Twinax device) due to the Twinax IOA requiring an IOP.   A Power 6 520 M15
(follow-on to the Power 5 515) can't have any external towers therefore, no
Twinax at all.  A Power 6 520 M25, can have an external tower, and only this
machine with an HSL2 attached loop (not a 12X attached loop) could have a
twinax.  

Here is the message I tell my customers:

	If you want the best get HMC, otherwise you LAN Console.  You win in
either case, and by the way, LAN Console is even easier to configure at
V6R1.

No - the model 520 can't have a Twinax Card placed in it's CEC (no IOP
support in CEC).

So you need to place the Twinax Card plus IOP in a Expansion Unit.
However, you can't configure the System to use the Twinax Card in the
Expansion Unit as a console without having a HMC.

As such, using a Twinax console is 100% pointless on the new machines
- but not impossible. That was my point.
