1.3.2 Component Overview
Figure 4 provides an overview of the important interface card components.
Positioning Notch
Aligns with the positioning key on the inverter chassis to ensure that the interface card is installed into
the correct communication port (refer to section 2.2).
Port 1 and Port 2 Ethernet Jacks
Either jack can freely be used in star topology networks (with external switch). In linear topologies, a
series of cards can be connected together by daisy-chaining one of the ports to the next inverter in line.
In ring topologies, MRP (Media Redundancy Protocol) must be supported by all devices on the network.
Standoff Mounting Hardware
The provided M3 x 12mm and M3 x 6mm screws are used to secure the card to the standoffs located on
the inverter’s control board. Refer to section 2.2.
Inverter Control Board Connector
Attaches to the inverter’s connector board, which may vary depending on the inverter model.
USB Port
USB 2.0 port with mini-B connector. Used to access the card via the Fuji Configuration Studio (refer to
section 5) and as a USB flash drive (refer to section 7).
Module Status and Network Status LEDs
These LEDs indicate the current status of the interface card and protocols in use. Refer to section 1.4.
Ethernet Link and Activity LEDs
One set of LEDs are provided for each Ethernet port. These LEDs provide insight into the Ethernet
network’s status and activity. Refer to section 1.4.
