connector, top row is against the top of the connector, a 2nd row against
the back of the connector, then a 3rd row along the bottom surface of the
Its about 2 inches wide, and about 3/10's of an inch high.
The chips on the card are small non-descript, about 3 or4 types of chips,
on the board itself most of the chips have a label next to them, U1 through
U49, and then there are several yellow chips labled RP1 through RP11. I
can't really find any sort of a name or indication on the card, here are a
A2091-66580 Rev C
Also, 4 red blinken lights inside the board, labeled CR1, you could only see
them when mounted inside the system if you already knew they were there.
Is there a place on hp's site you can search part numbers, I looked last
time I was at the site, but could not find anything.
