Install/remove daughterboards on the NTAK09 DTI/PRI card
Procedure 27
Mounting the daughterboards on the NTAK09
Use these guidelines to mount the NTAK20 CC and the NTAK93 DCHI or
NTBK51 DDCH daughterboards on the NTAK09 DTI/PRI card. Because of the
physical layout of the mother and daughterboards, the NTAK93 or NTBK51
should be mounted before the NTAK20. Work on a flat surface when mounting
or removing daughterboards.
1 Visually inspect the connector pins on the underside of the
daughterboard. Straighten and re-align any bent pins prior to mounting.
2 Place the NTAK09 down flat on an anti-static pad.
3 From an overhead view, with the daughterboard parallel above the
NTAK09 and the connector pins aligned over the connector sockets, align
the mounting holes on the daughterboard (Figure 79 on
the tops of the standoffs on the NTAK09.
