m1000e enclosure CMC cards password reset jumper

Hello folks,

I am configuring a refurbished m1000e blade enclosure.  It contains 2 CMC cards.  I see they are getting DHCP from my firewall and I can reach the web interface but I cannot log in with root/calvin . I assume the previous owner set a CMC password and I'll need to reset it via the jumper method.

I am confused because when I pull the cards out, it appears a jumper is in place already. The documentation says that when a jumper is in place, the default password should work. I have tried removing it, reseating the card (it boots back up),  trying the root/calvin login without the jumper,  replacing the jumper, and trying again, but still I cannot log in to the CMC web interface.

I am attaching a picture in hopes that someone can verify, is this small piece of plastic, that is seated on the password reset jumper pins a real jumper? I wonder if I need to order a real jumper and if this is just a placeholder. It's so small I cannot see if there is any conductive material inside or if it is only plastic, and I don't know why it would already be in place on both of my CMC cards unless the previous owner put it there.
