library.
10 Remove the new SCB from its packaging. Wrap the old SCB in the
antistatic bag that the replacement SCB was wrapped in.

components face up. The flat part of the board faces down. The
thumbscrews are on the upper side of the SCB back plate (see
Figure 58 on page 226).

travel, press firmly on the back panel of the SCB to “snap” it into
place.
13 Tighten the two thumbscrews finger tight.
14 Connect the Ethernet cable to the LEFT Ethernet port on the SCB (as
viewed from the back of the library; see Figure 58 on page 226).
