6. Begin pushing the board into the slot until the extractor handle starts to engage the metal extractor
plate (the extractor handle moves into its folded position).
When the extractor handle starts to lift, flip the handle toward the center of the board until it snaps
into its folded (locked) position (which firmly seats the board).
7. Fasten the screw (which was removed in Step 4) that holds the board in place.
8. If the enclosure was powered down – Reapply power.
9. Verify that the system recognizes the board:
a. Attach a PC to the serial port on the enclosure with an RS-232 null modem cable (pinout:
5 GND to 5 GND, 2 RXD to 3 TXD, and 3 TXD to 2 RXD).
b. Open HyperTerminal (typically at start/Programs/Accessories/Communications/HyperTerminal)
and set the port settings to: baud rate = 9600, data bits = 8, stop bit = 1, parity = none, and
flow control = none.
c. Enter ~scri4v3!
d. Check to be sure the new board is included in the list (FIG. 71). If not, reseat the board and enter
the command again.
(Do not
disconnect HyperTerminal until after Step 13 is successful.)
10. If applicable – Attach the cable management bar (do not over tighten screws).
Note: If using a cable management bar, tie the cable to the cable management bar far enough below
the connector to allow for the manufacturer’s recommended bend radius. The bend radius for
AMX SC terminated fiber cables is 2 inches (5 cm).
11. Attach the cables to the board’s connectors* and reconnect any other cables that were disconnected
in Step 3 (if applicable – tie cables to cable management bars).
If the system is not powered down:
 For connecting a DGX SC Optical input board – Avoid direct eye exposure as you
(a) remove the dust plugs from the SC fiber connectors on the board, (b) remove the dust caps
from the fiber cables, (c) establish the connections, and (d) apply power to the DGX TX
Transmitter modules that are connected to the inputs.
 For connecting a DGX SC Optical output board – Avoid direct eye exposure as you
(a) remove the dust plugs from the SC fiber connectors on the board, (b) remove the dust caps
from the fiber cables, and (c) establish the connections.
12. If the enclosure was powered down – Reapply power.
*If you need cabling information, see the specific board chapter in this manual.
