Subject: Re: bnx2x + SFP+ DA/2.6.33.3: Got bad status 0x0 when reading from SFP+ EEPROM -> SFP+ module is not initialized
Date: Thu, 20 May 2010 13:25:31 -0700 [thread overview]

Some simple/simplistic thoughts/questions...
Has the DAC been used successfully prior to this?
Do you have another HP ProCurve 10-GbE SFP+ 7m Direct Attach Cable (J9285B) to try?
There's a transceiver and presumably an EEPROM at both ends of a DAC right? If
the EEPROM at one end were "bad" might the 57711 be happier with the other end
of the DAC? Getting some sort of error message at the switch side, which may
(or may not) have more detailed diagnostics might help.
