Galaxy Express – Module Installation

Required and Optional Cards

The list of plug-in cards are described in Galaxy Express – Platform and Hardware Overview. All cards are inserted in the same manner into the Galaxy Express chassis

Regardless of which slots a card to which a card is restricted, the same process is used for installed and removing them.

Card Insertion

Each slot is labeled on the chassis (1 and 2).  Each of the slots has a both an front and rear guide rail on each side for ensuring proper alignment of the card prior to inserting. The slots and rails can be seen below:

When installing the card, make sure the side of the circuit board with most of the components is facing upward, and guide the upper and lower edge of the card into the upper and lower guide rails. Holding the latching screws, slide the card all the way and gently rock the card to seat it in the rear connector. Tighten the latching screws to the chassis to ensure a solid fit.


It is possible to install the card upside down if the card is not properly inserted into the guide rails, which could damage the card.  Before seating the card into the connector, verify that 1) the card is sliding within the guide rails and that the text is either oriented toward the left-hand side or toward the bottom of the chassis!


Disconnect the power cords prior to inserting or removing any cards.

Once you have installed the cards in the Galaxy Express chassis, you can follow the same steps for initial configuration as for the Galaxy Expand as described in Galaxy Expand – Initial Configuration
