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.

=============================================================== From: "Mike (meuon) Harrison" ------------------------------------------------------ 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) https://www.mellanox.com/related-docs/user_manuals/SB77X0_SB78X0_SB67X0_1U_IB_Systems_Quick_Installation_Guide.pdf Is that what you need? I got several ways to do that...
