914-EX
The 914-EX (Ethernet expansion card) provides an additional two (2) 10/100/1000 BASE-T(X) ports to a 914-HDE
system. These ports are multiplexed into the 914-HDE optical data stream. This design is switchless ensuring no
mixing of Ethernet traffic between ports, i.e. data input to port 1 is an output on port 1 at the far side of the optical
link. Diagnostics from this card are provided to the 914-HDE and are available to the Model 914 Diagnostic GUI.
The 914-EX can use a single medium speed expansion channel for up to 1000 Mb/s of bandwidth dynamically
shared between the two Ethernet ports, or two medium speed expansion channels allowing for a full 1000 Mb/s of
bandwidth per Ethernet port. Care must be taken to ensure the 914-HDE motherboard optical interface has sufficient
bandwidth to support the Ethernet traffic. Actual bandwidth requirements are based on the external devices
connected to the Ethernet ports.
