Closing the main unit case
To close the main unit case
1 Attach one end of a grounding strap to your wrist and the other end to a grounded metal
surface.
2 Place the top of the case on top of the main unit case. Make sure the side edges of the case are
aligned and the front of the top is back about 1 cm (3/8 in.).
3 Slide the top of the case forward until it clicks in place (see Figure 78 on page 202).
Note: Do not force the cable.
The connector on the fan cable is designed to prevent the cable from being
inserted backwards. If the cable does not insert properly, check that the raised
edge on the fan cable connector faces the plastic tab on the header.
Caution: Use only the screws that were originally used to secure the Router card.
Using other screws may interfere with proper installation.
