Image Description: Two m701-MP4 cards are shown connected side-by-side using a WA235 ribbon cable. The cable connects from connector J3 on the lower slot card to connector J4 on the adjacent card.

3. Install the I/O Cards as a pair by inserting it from the inside of the unit and tilting the DB25 input connector down first, then aligning the card edge connector (PCI-E slot). When aligned, press down on the back of the cards to seat the connectors. Repeat for any other cards to install.
Image Description: Hands are shown inserting two I/O cards into the m701 unit. The DB25 input connectors are tilted downwards to align with their slots before seating the card edge connectors.

4. Install the I/O Card cover plates with the H035 3/32" Allen screws that were previously removed and H165 3/16" hex standoffs. The H165s will have thread locking compound pre-applied. Place the H591 Dust Cap on the higher slot number card.
Image Description: The front panel of the m701 unit is shown after installation, featuring multiple I/O cards with their DB25 connectors. The H591 Dust Cap is visible on the card in the higher slot number.
