depressed tab and keeps it depressed. The left front standoffs
should now be free of their holes.
8 On the middle front right-hand side of the front panel, pull the
plastic tab (Y on Figure 4-10) carefully toward the rear of the
chassis and simultaneously press in the right side panel of the
aluminum chassis until the front panel is partially released. The
right front standoffs should now be free of their holes.
NOTE At this point, the front panel is only held to the motherboard by
an edge connector.
9 Using gentle pressure on both sides of the front panel, push the
front panel away from the motherboard to release the edge
connector and free the front panel completely.
10 Insert the typeN-to-SMA connector-adapter into the Channel 2
hole on the front panel (remove the hole-plug, if necessary), so
that the typeN connector is on the front side of the front panel.
11 On the back side of the connector-adapter, place the washer plate
and the 14mm hex nut over the SMA connector and secure. See
Figure 4-11.
12 Make sure the word "LIFT" is visible on the washer-plate and that
the "LIFT" tab on the washer-plate is not underneath the hex nut.
