This switch is advertised as being part #49Y7887, but is actually #49Y7931. The package it came in has the correct part number, but the cable inside did not (see attached photo). We have an IBM G3816 switch and two 49Y7887 cables attached to it that work perfectly. This cable was rejected by the switch:

While it may be compatible with some switches, it is not compatible with ours, which specifically requires part #49Y7887. It's worth noting that there seem to be a lot of these cables out there. I also bought one sold as a new 49Y7887 from a seller on an online auction site, and the cable that arrived was identical to this one (same label, same color, same manufacture date, even). The packaging on that one also said 49Y7887, but the cable inside was 49Y7931.
