Install the NTBK50 PRI card

269

Step

Action

1

Visually inspect the connector pins on the underside of the
daughterboard. Realign any bent pins prior to mounting.

2

Place the NTBK50 down flat on an antistatic pad.

3

From an overhead view, with the daughterboard parallel above
the NTBK50 and the connector pins aligned over the connector
sockets, align the mounting holes on the daughterboard with the
tops of the standoffs on the NTBK50 (see

Figure 86 "Daughterboard

installation" (page 270)

).

4

Slowly lower the daughterboard toward the NTBK50, keeping the
standoffs in line with all four holes, until the holes rest atop the four
standoffs.

If more than slight pressure is required at this point, the connector
pins might not be aligned with the connector socket. If so, lift the
daughterboard off the NTBK50 and return to step 2.

5

Gently apply pressure along the edge of the board where the
connector is located until the standoffs at the two corners adjacent
to the connector snap into a locked position. Then press down on
the two corners on the opposite side until they lock into place.
