[c-nsp] Problems with 6509 upgrade kit

[Chris Roberts]

Thanks for the ideas.

We have the chassis running at 220-240V (UK) so all should be well there.
We've now tried 2 different upgrade kits, both of which have the same
problems, with 4 different PSUs. We're going to try some things with the
power for our next attempt however all seems well on the power front, with
'sh power' giving good results (900W / 1900W used).

TAC recommended the command 'hw-module fan-tray version 2', however this
doesn't exist in our 12.2(18)SXD IOS, although its listed on the website as
supported by the Sup720 in 12.2(14)SXD. TAC also claim it should never be
needed on a Sup720, however our fan-tray is definitely being recognised as a
WS-C6509-NEB-FAN rather than a FAN2, and it 'feels' like there's something
simple like this missing.

TAC also claim it is most likely a chassis problem, and want us to send them
the Sup720s, all the PSUs and fan trays for testing and proving in the lab
so that they can then rule our chassis as the problem by default.

:(

Cheers,
Chris.
