Use these guidelines to remove the NTAK20 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 may not carry
daughterboards, depending on the system configuration. At least one
NTAK20 (per system) is always required.
Set the switches on the NTAK09 DTI/PRI card according to the table below.
