There are (at least) three different “polarities” of MPO cables. Depending on what you connect together you need different polarity type. Unfortunately this
is very confusing topic and often either not well known or forgotten. In particular, NetApp does not list cable polarity.
See
http://www.fiber-optic-tutorial.com/understanding-polarity-in-mpo-system.html for tutorial.
You can check where lights are on both ends; this is probably the most easy way to find out if your cable is correct.

Those are optical cables, that got shipped with the card and the transceivers.
According to HWU, those are the transceivers:
They look exactly like these and HWU calls them X65402.
The connector looks exactly like the MPO connector which can also be seen in HWU and hast he cable number X66200-2 – so this is what I got:
X1144A Adapter
X65402 Transceivers
X66200-2 Cables
Should all play well with 9.1RC2 on the AFF-A300.
Since 9.1 has already been released, I’ll upgrade this system to 9.1 and see if that changes anything – maybe there’s a reason why they call it RC

Betreff: Re: X1144A - No link
OK, a little confused now. Are you trying to use copper or optical?
According to HWU, the X1144A as QSFP+ slots and the cable ends look identical to the SAS cables.
The NetApp end should be any supported copper cable with a QSFP+ end or an optical transciever (X65402A, mfg 332-00389).
The optical transciver will have the QSFP+ going into the filer and exposing the MPO end for your optical cable
Since it looks like you are trying to use Optical, are you *sure* the optical transcivers are the right ones for that card?

That’s the 2-port 40G card with QSFPs and those funny new cables, no breakout cables.

Curious...are you using it as a two-port 40Gb card or using the breakout cable?

Good question – I’m using the QSFPs and the cables that came with the cards, so I’m positive that those should be supported.
But I’m trying to find out.

what is the cable that you are using? Anything supported?

Hi,
I’ve just installed those fancy X1144A cards in one of our AFF300 systems and it seems they’re getting recognized properly, but I’m not able to get a link on them.
sysconfig says:

4 entries were displayed.
For testing purposes, I did connect e2a on node1 to e2a on node 2 and I already tried exchanging the QSFPs and cables, but still no dice.
Any idea what could be wrong here?
According to HWU, the minimum required OS version is 9.1RC2, which is exactly what is installed currently:
