Would anyone have a firmware upgrade cable for a IB switch I could borrow?
It only has a i2c interface and I can=E2=80=99t find the original cable.  I=
ts $400
from Mellanox.

I've got quite a selection of serial/UART to USB interfaces, but not i2c, 
The manual talks about;

1 x Harness RS232 2M cable – DB9 to RJ-451 (included in SB7X00, SB7780 and 
SX67X0 only)

and shows what I would have called a "Cisco Cable" (rj45 serial)

Is that what you need? I got several ways to do that...

If you need a blue Cisco RJ45 serial cable, please, I have boxes of them.

With Gratitude,
