1 Prizm 4 Port 10/100/1000 Mbps Ethernet Switch (P/N: 201640-
xxx) Overview
The 4 Port 10/100/1000Mb s Ethernet Switch is designed to be used as one of a air to rovide a 1Gb s
Ethernet fiber o tic data link between two 4 ort switches. Each board is functionally identical to the
corres onding board at the o osite 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 air, bidirectional, full-du lex communication can be achieved over a single fiber o tic cable. Each
of the orts on the switch inde endently su orts communication at 10, 100, or 1000Mb s and is 802.3ab
com liant. The switch su orts u to 4k unicast MAC addresses. The boards are shi ed in a standard
configuration that should be a ro riate for most users however, some additional features that can be
rovided on an as needed basis include: su ort for jumbo frames of u to 9728 bytes, ort based virtual
LAN, broadcast storm su ression, and ort mirroring. Contact Moog Com onents Grou technical
su ort if you have questions about these or any other features that may be required.
1.1 4 Port 10/100/1000 Mbps Ethernet Switch Re ision History:
The 4 Port 10/100/1000 Mb s Ethernet Switch (201640-xxx) has gone through the following rinted
circuit board (PCB) revisions:
PCB Revision A Original design. Not currently in roduction.
PCB Revision B Revised design. Not currently in roduction.
PCB Revision C Finalized design. Current roduction revision.
1.2 4 Port 10/100/1000 Mbps Ethernet Switch Dash (-) Number Definitions:
The 4 Port 10/100/1000 Mb s Ethernet Switches have a Dash Number a ended to the art number.
This Dash Number identifies the s ecific board configurations:
-001A Prototy e configuration. Obsolete.
-002A Corres onds to rev B PCB revision. Obsolete.
-003A Rev C PCB revision base configuration. Currently in roduction.
1.3 4 Port 10/100/1000 Mbps Ethernet Switch Operation
The 4 Port 10/100/1000Mb s Ethernet Switch boards rovide 4 co er RJ-45 orts suitable for carrying
standard 10/100/1000Mb s Ethernet and a single fiber o tic ort which o erates at u to 1.25Gb s. The
boards also rovide the interface for a daughter board connection and a diagnostics ort. A block diagram
of the basic 4 Port 10/100/1000 Mb s Ethernet Switch I/O is shown on the following age and it is
ex lained in the subsequent aragra hs.

The transmit ortion (u link from vehicle to surface) of the 4 Port 10/100/1000 Mb s Ethernet Switch
takes in 4 standard 10/100/1000Mb s Ethernet signals via RJ-45 connectors and rocesses the received
signals through an onboard Ethernet switch. If needed, ackets are routed to the fiber o tic transmitter for
delivery to the switch at the o osite end of the link. The receive ortion of the 4 Port 10/100/1000 Mb s
Ethernet Switch acce ts the o tical signal from the remote end of the link, and recovers any Ethernet
ackets resent. Those ackets are then routed, via the onboard Ethernet switch, to the a ro riate RJ-45
connector on the board.
The 4 Port 10/100/1000 Mb s Ethernet Switch requires a +5VDC ower source rovided through the 2-
in Phoenix connector at J5. The boards have an on-board 5V to 3.3V, 2.5V and 1.2V converters to
rovide ower for the com onents that use those su ly voltage.

1.6 Power Section Testing
Note: The +1.2V ower LED (D1) is not functional. The board will operate properly and
+1.2CVDC is being supplied to the board whether this LED is illuminated or not.
If the +5V Power LED, the +3.3V Power LED, and the +2.5V Power LED are out:
• Check for continuity of fuse F1 with an ohmmeter.
• Re lace fuse if blown.
If only the +5V Power LED is out:
• Verify +5V DC is resent at the source
• At J5 if owered off of external ower
• At J2 if owered off of the daughterboard ex ansion header.
• If +5V is not available re lace the board with a s are.
• If +5V is available check the dis lay LED (D10).
If only the +3.3V Power LED is out:
• Verify +5VDC across C79 (re lace board if +5VDC is not available)
• Verify +3.3VDC across C77
• If +3.3V is not available re lace the board with a s are.
• If +3.3V is available check the dis lay LED (D9).
If only the +2.5V Power LED is out:
• Verify +5VDC across C75 (re lace board if +5VDC is not available)
• Verify +2.5VDC across C65
• If +2.5V is not available re lace the board with a s are.
• If +2.5V is available check the dis lay LED (D7).
1.7 Optical Section Testing
If the FIBER LED, (bottom LED of D2) is off or flickering, one or more of the following conditions is
likely:
• The fiber is broken or damaged.
• The o tical transceiver module is defective.
• Excessive light loss (low received o tical ower) is being ex erienced.
• The 4 Port 10/100/1000Mb s Ethernet Switch (not the o tical transceiver module) is
malfunctioning.
• There is not enough attenuation in the o tical link and the receiver is saturating.
• Check the o tical level with an o tical ower meter and ins ect all fiber o tic connections
including WDMs and sli rings.

Page 12 of 13
To determine if the fiber is broken, a laser module is out, or the board is malfunctioning, first:
• Verify that the o tical transceiver is tight in its socket.
• Check all fiber o tic connections including WDMs and sli rings to make sure that they are not
causing the roblem.
• Check that the o tical fiber cable is straight at connectors on board for minimum o tic loss.
1.8 DIAGNOSTIC OVERVIEW
The Fiber O tic Modem Board has been re-designed to include hardware and firmware for monitoring
various arameters of interest. This ca ability is accessed via a 2 in Phoenix connector on the front
anel that carries bi-directional RS-485 telemetry to the modem. The diagnostics modem will ty ically
be used in conjunction with a user-su lied PC on the surface, which has been loaded with PRIZM
Modem Monitoring S/W.
The initial release of the Diagnostics feature required that the user allow for the use of one RS-485
channel in the multi lexer system for connectivity between the to side Diagnostic PC and the remote
multi lexer. Later releases are ca able of carrying the Diagnostics across the fiber link via a high-s eed
data bit on the back lane.
NOTE: The diagnostics feature in no way interferes with normal operation of the modem – it is
not necessary to be running the diagnostics s/w for the modem to work.
1.9 Communications Hardware
The diagnostics ca ability is accessed via the 2- in RT+/RT- connector on the front anel of the modem,
which rovides the RS-485 connectivity to the on-board rocessor for diagnostics communications. The
initial release of the Diagnostics feature required that the user allow for the use of one RS-485 channel in
the multi lexer system for connectivity between the to side Diagnostic PC and the remote multi lexer.
RS-485 was used because of its multi-dro ca ability, which in this case allows all the modems to be
communicated with via a single channel. In later revisions of the diagnostic modems, the ability to carry
the diagnostic data across the fiber link using one of the high-s eed back lane bits was included. In this
configuration, no RS-485 multi lexer channel is needed, however one of the high-s eed data bits is
sacrificed. NOTE: A modem configured to operate over the back plane will NOT operate correctly if
used with a modem that is configured to operate over a RS-485 multiplexer channel.
The user is required to communicate with the modems of the system via RS-485. A ty ical installations
is shown in the following drawing. This details a diagnostic connection through a RS-485 submux
channel.
