If the cage is wired to a vendor-proprietary pinout, no off-the-shelf cable will train it correctly — and that is worth knowing before you order rather than after.\u003c\/p\u003e\n\u003ch3\u003eCan I use only one of the two legs?\u003c\/h3\u003e\n\u003cp\u003eThe cable is passive, so leaving one leg unconnected does not damage anything, but you would be paying for a fan-out and getting half the lanes.
