Nortel Networks NN43001-301 manual Step Action

Install the NTBK50 PRI card 269

Step Action

1Visually inspect the connector pins on the underside of the daughterboard. Realign any bent pins prior to mounting.

2Place the NTBK50 down flat on an antistatic pad.

3From 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)).

4Slowly 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.

5Gently 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.
