Basic stages of controller disassembly.

Procedure 3

Disassembling the controller.

Step 1

Remove all power

from the controller. (See previous

Step 2

Remove the plastic cover from the unit. See

“Removing and Replacing the Cover,”

Step 3

Remove the four Philips head screws that secure the metal shield, and set them aside.

Step 4

Remove the metal shield and set it aside.



To do this, carefully pry up from the top (hole vented side) first, then push out the other side to slip
the port holes past the port edges. Then lift the shield up and away.

Note

Be mindful of the “side clips” on the controller’s two Ethernet ports.

Step 5

Use a 1/4" (7mm) nutdriver to unscrew the four metal standoffs, and set them aside.

Step 6

Carefully pry up the NPM board, noting that the two-row, 50-pin connector is on the option card side.
Keep the board level as you work it loose from this connector.

Step 7

Set the NPM board aside. Note the jumper block on the base board behind the RS-485 port.
