1 Prizm 4 Port 10/100/1000 Mbps Ethernet Switch (P/N: 201640-
xxx) Overview
The 4 Port 10/100/1000Mbps Ethernet Switch is designed to be used as one of a pair to provide a 1Gbps
Ethernet fiber optic data link between two 4 port switches. Each board is functionally identical to the
corresponding board at the opposite end of the link. The only difference between the two boards, on
occasion, is the wavelength of the transmitting laser. By using a different wavelength for each transmitter
in the pair, bidirectional, full-duplex communication can be achieved over a single fiber optic cable. Each
of the ports on the switch independently supports communication at 10, 100, or 1000Mbps and is 802.3ab
compliant. The switch supports up to 4k unicast MAC addresses. The boards are shipped in a standard
configuration that should be appropriate for most users however, some additional features that can be
provided on an as needed basis include: support for jumbo frames of up to 9728 bytes, port based virtual
LAN, broadcast storm suppression, and port mirroring. Contact Moog Components Group technical
support if you have questions about these or any other features that may be required.

4 Port 10/100/1000 Mbps Ethernet Switch Operation
The 4 Port 10/100/1000Mbps Ethernet Switch boards provide 4 copper RJ-45 ports suitable for carrying
standard 10/100/1000Mbps Ethernet and a single fiber optic port which operates at up to 1.25Gbps. The
boards also provide the interface for a daughter board connection and a diagnostics port. A block diagram
of the basic 4 Port 10/100/1000 Mbps Ethernet Switch I/O is shown on the following page and it is
explained in the subsequent paragraphs.
