Inserting/changing the card
The MMC is designed for removal and insertion under power. The slanted corner
of the MMC prevents it from being inserted the wrong way round (reverse voltage
protection).
The module slot is behind the front door on the IM151-3. The front door has an
extended edge at the bottom for opening.
The module slot has an ejector mechanism for removing the card. Press the
ejector mechanism with a small screwdriver or ballpoint pen to eject the card.
