[c-nsp] Problems with 6509 upgrade kit

[Chris Roberts]

We (unsuccessfully) attempted to upgrade one of our 6509 chassis to Sup720s
at the weekend. Of all of the high tech components that could have had
problems, it seems the fan tray or PSUs failed. :(

I'm wondering if anyone has seen similar. We upgraded the chassis with the
WS-C6509-NEB-UPGRD kit (high speed fan tray, and pointless seeming backplate
change), and the power supplies to the WS-CAC-3000W. Connected the appalling
external power connectors to the power supplies and the fan trays. Upon
booting, the fans did not spin, and the system complained that the fan tray
had failed. Neither power input on the fan tray was showing a green light on
input power, however both PSUs had a green light on output power. We checked
the cables/cabling between the two and all seemed to be good.

What I found odd however, is that on booting the system, the system
complained not only of a fan tray failure, but also had a major fault and
complained that the fan tray needed upgrading. I can only assume that
without the external power the card appears to the chassis as a normal fan
tray and not a FAN2 tray? I also find it a bit odd that the PSUs read an
output of 42V DC/17A (which is repeated in the manuals) and the fan tray
states an input of 48V DC.

Also, after replacing the Sup1As in the chassis, the Sup1As complained of a
lack of power and failed to boot the two WS-C6348-RJ-45 cards.
Unfortunately, by this point our time was limited, so I didn't have time to
fully investigate why this was happening, and we simply replaced the
original 1300W PSUs. Is there an incompatibility between the Sup1A cards and
3000W power supplies?

Anyone think of anyone I've missed before I RMA the power supplies and the
fan trays?

Cheers,
Chris.
