Adding an additional Remora card to your existing A400 allows you to add an additional twelve (12) ports of either FXO or FXS connectivity, by installing one to six modules (FXO-2 modules for two FXO ports, or FXS-2 modules for two FXS ports.
Each A400 can support up to 4 cards, including the base PCI card, for a total of 48 available ports.
This card connects to your existing A400 through the use of an external bus connector, which attaches to the rear of the card. It is therefore recommended that you install these cards next to each other in the chassis.
NOTE: When ordering this card to add to your existing A400, please ensure you select the right bus connector for the total number of cards, including the base PCI card, you expect to install in your system. For example, if you plan on having 24 ports in total, you will need the "2 Card Bus Connector", or for 48 ports, you will need the "4 Card Bus Connector".
