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.
1.1 4 Port 10/100/1000 Mbps Ethernet Switch Revision History:
The 4 Port 10/100/1000 Mbps Ethernet Switch (201640-xxx) has gone through the following printed
circuit board (PCB) revisions:
PCB Revision A Original design. Not currently in production.
PCB Revision B Revised design. Not currently in production.
PCB Revision C Finalized design. Current production revision.
1.2 4 Port 10/100/1000 Mbps Ethernet Switch Dash (-) Number Definitions:
The 4 Port 10/100/1000 Mbps Ethernet Switches have a Dash Number appended to the part number.
This Dash Number identifies the specific board configurations:
-001A Prototype configuration. Obsolete.
-002A Corresponds to rev B PCB revision. Obsolete.
-003A Rev C PCB revision base configuration. Currently in production.
1.3 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.

The transmit portion (uplink from vehicle to surface) of the 4 Port 10/100/1000 Mbps Ethernet Switch
takes in 4 standard 10/100/1000Mbps Ethernet signals via RJ-45 connectors and processes the received
signals through an onboard Ethernet switch. If needed, packets are routed to the fiber optic transmitter for
delivery to the switch at the opposite end of the link. The receive portion of the 4 Port 10/100/1000 Mbps
Ethernet Switch accepts the optical signal from the remote end of the link, and recovers any Ethernet
packets present. Those packets are then routed, via the onboard Ethernet switch, to the appropriate RJ-45
connector on the board.
The 4 Port 10/100/1000 Mbps Ethernet Switch requires a +5VDC power source provided through the 2pin Phoenix connector at J5. The boards have an on-board 5V to 3.3V, 2.5V and 1.2V converters to
provide power for the components that use those supply voltage.
