Caution – The electronic components and solder joints on the bottom of the CPU
card are fragile. Use care to avoid scraping the bottom of the CPU card on the
chassis or door when removing or installing it.

from its backplane, then carefully pull it out of the server (see FIGURE 4-17).

tracks inside the server chassis, then slide the CPU card into the tracks.

backplane.

place.
