Hi,

I'm tyring to connect a HFI card to an Omni-Path Edge Switch 100. The
switch detects the QSFP just fine:

Cable05  OEM         Copper     3 meter   20.87  ???  MCP1600-E003-C    6   M9AL0003          Valid

But on the host side, I only get:

[   53.060613] hfi1 0000:01:00.0: hfi1_0: wait_for_qsfp_init: No IntN detected, reset complete
[   53.082820] hfi1 0000:01:00.0: hfi1_0: i2c_bus_write: bus 1, i2c slave 0x50, offset 0x7f, len 0x1; write failed, ret -6
[   53.114661] hfi1 0000:01:00.0: hfi1_0: port 1: QSFP chain 1 can't write QSFP_PAGE_SELECT_BYTE: -6
[   53.137353] hfi1 0000:01:00.0: hfi1_0: QSFP not responding, waiting and retrying 0

Any hint why the card doesn't find the plugged in QSFPs ?

Please refer to the Intel Omni Path cable support matrix for a list of supported cables: http://www.intel.com/content/www/us/en/high-performance-computing-fabrics/omni-path-cables.html. If you need help with cables not on this list, please contact the cable manufacturer or supplier for assistance.

Thanks
