Installing a QPI wrap card
Wrap card

In a one node server only, if your server has more than two microprocessors
installed, you must install two QPI wrap cards in the server.
To confirm that the server supports the QPI wrap card that you are installing, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.
To install a QPI wrap card, complete the following steps:
1. Read “Safety” on page v and “Installation guidelines” on page 38.
2. Turn off the server and peripheral devices, and disconnect the power cord and
all external cables.
3. Rotate the blue release latch on the QPI blank handle, pull the handle to the
open position, and pull the blank out of the server.
4. Rotate the blue release latch on the QPI wrap card handle and pull the handle
to the open position.
5. Push the wrap card into the bay, and rotate the handle to the locked position.
6. Reconnect the cables and power cords (see “Connecting the cables” on page
79).
7. Turn on all attached devices and the server.
8. If you have other devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 79.
