Hello All I purchased a Broadcom 57412 10Gb NIC, Dell part 540-BBUN, to install in my PE R540. I do not have a riser or low profile chassis, but it accommodates slimline cards.  The card is installed in SLOT_4 x16, the only one that accommodates the card.   Any insight is helpful.  Thanks PS- I know  540-BBUN has a full-height bracket; I can alter the slot's blank plate to accomodate.
