Changing Symetrix I/O Cards

Follow this sequence of steps to properly setup and configure cards in your Edge mainframe

  1. First, you must remove the lid. To do this, 3 phillips head screws need to be removed from the top of the mainframe. Slide the lid back and then up when removing. There is a lip that holds the front down to the chassis.

  2. If your unit has blank filler panels in the card slots, unscrew and remove them by removing the two black screws located on the outside of the mainframe.

  3. To remove an installed card, first remove the 2 stainless steel screws that mount the card bracket to the card. These screws are located on the inside.

  4. Next remove the stainless steel phillps head screw from the top of the card. Gently pull the card up to disconnect the 50-pin connector. The card is no longer attached to the mainframe. Carefully remove the card from the chassis.

  5. Remove the bracket for the I/O card by removing the two black screws located on the outside of mainframe.

  6. To install a new card, mount the bracket for the new I/O card to the mainframe chassis using the two black screws provided.

  7. Next, align and feed the connectors on the I/O card through the opening in the bracket and align the single screw hole in the card with the standoff on the motherboard. Visually look through this hole and align with the standoff and then, carefully, apply an even downward pressure until you feel the card seat into the 50-pin socket. You will likely need to carefully move the board side to side to align the 50 pin connector. Use one of the stainless steel phillips head screws provided and mount the board to the standoff. Don’t over tighten this screw. The 50-pin connector on the Edge cards should not be under any tension when properly installed.

  8. Now, install and tighten the 2 screws that mount the bracket to the card. This should ALWAYS be the last step before replacing the lid.

  9. Finally, replace the lid.

TheIN, OUT, AECandDIGILEDs illuminate in combination to indicate the card type installed. For example, an IN illuminates to indicate an analog mic/line input card, whereas IN and DIGI illuminate to indicate a digital input card. If the card is installed properly the card type LED will illuminate.
