cabinet to your wrist.

from the cabinet.

the settings on one of the following:
— the NTAK01 CPU/Conf
— the removed NTBK45 System Core card
9 Remove the jumper plug from connector J7 on the component
side of the NTDK20 SSC card, as shown in Figure 7 on page 41.

expansion cabinet connected with fiber-optic cable. You need the J7
connector plug to activate the Ethernet capability (which is not
available with copper connected cabinets).
The NTDK20 SSC card has components on both sides of the circuit
board. Be careful not to damage any of the components when handling
the card.
10 Install the NTDK26 Backwards Compatible Daughterboard on the
NTDK20 SSC card, as shown in Figure 7 on page 41.
Note: Make sure you have removed the J7 connector plug (see
Step 9 on page 40).
11 Install the Software Daughterboard and the Security Device on
the NTDK20 SSC Card as shown in Figure 7 on page 41.
