The UCS B200 supports a single mezzanine card, B260/B420 support two cards, and B460 supports four cards. The procedure for installing these cards is the same for all servers:

1. Make sure you are wearing an ESD wrist wrap grounded to the blade server cover.
2. Open the server's top cover.
3. Grab the card by the edges and align the male molex connector with the female connector on the motherboard.
4. Press the card gently into the slot.
5. Once card is properly seated, secure it by tightening the screw on the top.

Removing a mezzanine card is the reverse of the preceding process.
