Abstract:
1. A method for accessing cable vital product data (VPD), comprising: detecting the presence of a cable connected through interface circuitry to a logic card to couple the logic card to an external device, the cable including a non-volatile memory storing cable VPD and having a selected line from the non-volatile memory to the logic card which is coupled to ground during normal operation of the external device; disconnecting the selected line from ground in response to detection of the cable; reading the cable VPD over the selected line from the non-volatile memory; reconnecting the selected line to ground; and tuning the interface circuitry in response to the cable VPD; Wherein reading the cable VPD comprises reading at least one of a length of the connected cable and a wire size of the connected cable; and wherein tuning the interface circuitry comprises adjusting amplification of signals being transmitted on the connected cable.
