Epica DGX 32 Instruction Manual
Caution: Each Epica DGX 32 Board has an EMI (Electromagnetic Interference) gasket along the left
edge of the face plate to ensure the boards fit snugly. Handle the boards carefully to avoid dislodging
or damaging this gasket on the board being installed and
on the board to its right.
5. New board – With the board’s extractor handle in the extended (unlocked) position, line up the
board’s edges on the board guides that are along the top and bottom of the board slot (FIG. 47).
Begin pushing the board into the slot until the extractor starts to engage the metal extractor plate
(lift into its folded position).
When the extractor handle starts to lift, flip the handle upward until it snaps into its folded (locked)
position (which firmly seats the board).
6. Fasten the screw at the top of the board.
7. 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. (b) Open HyperTerminal and set port settings to: baud = 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. If not, remove the board, reinstall it, and
enter the command again. (Do not
disconnect HyperTerminal until after Step 11 is successful.)
8. 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).
9. Attach the cables to the board’s connectors and reconnect any other cables that were disconnected
in Step 2.
10. Replace the connector numbering plate that was removed in Step 1.
11. Execute a test switch using a connection on the new board.
If the test switch does not work, see “Board Troubleshooting” on page 140.
If you need cabling information, see the specific board chapter in this manual.
