4 Slowly lower the daughterboard toward the NTAK09, keeping the
standoffs in line with all four holes, until the holes rest on top of the four
standoffs.
Note: If more than a very slight amount of pressure is required at this
point, the connector pins are not aligned with the connector socket. If so,
lift the daughterboard off the NTAK09 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 also are locked into place.
Procedure 28
Removing the daughterboards from the NTAK09
Use these guidelines to remove the NTAK20 Clock Controller (CC) and the
NTAK93 DCHI or NTBK51 DDCH daughterboards from the NTAK09 DTI/PRI
card. Because of the physical layout of the mother and daughterboards, the
NTAK20 should be removed before the NTAK93 or NTBK51.
1 Starting at the two corners opposite the connector, gently lift each corner
out of the locking groove of the standoff.
2 At the two corners adjacent to the connector, gently lift the entire side until
the mounting holes are clear of the locking groove of the standoff.
3 To remove the connector pins, grasp the edge of the board adjacent to
the connector and lift gently.
If more than one NTAK09 card is installed, the additional cards might not carry
daughterboards, depending on the system configuration. At least one NTAK20
(per system) is always required.
