Inexpensive, good gigabit ethernet NIC?

We're looking for the following information about a (probably) 3rd party,
gigabit ethernet NIC for a P655 running AIX 5.1 (5.2 is possible but
unlikely, last I heard 5.3 was not possible in this case).

1) What vendors have good deals on GigE NIC for a P655 (price/performance
would hopefully be low). We'd even consider a refurb, if they're
available.

2) What precisely would be involved in installing that NIC? The machine
has 5 NIC's right now, all from IBM. They are 2 * 100BaseT, 2 *
1000BaseT, and 1 * an SP2 interface. I understand the SP2 wiring is
pretty sensitive to being giggled.

Thanks!

1) no idea

2) I assume this is a single p655 node with a RIO drawer? I thought the
p655's only took Federation SP switch adapters, not SP2 (Colony), but I
could be wrong.

Installing cards can be a pain with the blind swap cassets (You will
need to find cassets also if your system is missing them). It works if
you have enough patience. Also, there are several different styles of
cards, the type that have screws are the most difficult to assemble, the
"screw-less" are easier to work with. If you've never done it before
give yourself 2-3 hours to get the card in the bind swap adapter and
into the machine (That's no exageration). More if you aren't mechanicly
inclined.

Also, if you look on one of the cassettes, there is (usually) a URL to a
document which describes (pictures and everything <G>) how to extract
the adapter and reassemble things...not sure how "mechanically inclined"
I am (let's put it this way, I once put a faloojin pin in a felacme
rod - didn't do too well <G>) but I can now swap out an adapter
(regardless of the casette type) and reassemble and reinserted in the
drawer in under 15 minutes.

BTW, you *are* aware that the cassette/adapter can just be pulled out of
the drawer as long as it's NOT assigned to a LPAR, yes? (took me forever
looking for a "hot swap" utility in the managed system - dohhh) :-O

I think that an adapter/slot not assigned to a partition cannot be
removed. You have to assign the adapter to a partition to be able to
'power-off' the slot to place/remove the adapter without damage.

Nope - just (carefully) extract the cassette, put in the new one,
refresh ("rebuild") the managed system...wait a few minutes and voila.
Done it multiple times w/o issue. I do agree, it is more "logical"
doing it by assigning the slot to an LPAR but that's NOT a requirement.
