Installing the Expansion Mother Board
The NX7E-24EPMB is the expansion mother board which increases the capacity of the system from

that the expansion power supply (NX7E-12PS) is also required.
The NX7E-24EPMB can
accommodate three NX7E-
408U-A1 units and one NX7E-
008U-A1 unit.

Mount the NX7E-
24EPMB board in the Main
Equipment and joint the EXP

connector on the main mother
board (NX7E-12MB).
Step 2:
Insert the four screws,
and screw the board to Main
