1.0 Introduction
A highly reliable managed Ethernet switch is required for use in subsea control networks to provide both copper
and optical links for 10/100/1000 Mbps communications using standard open protocols.
Focal’s Model 922-MES board is a layer 2 managed Ethernet switch (MES) with ten ports capable of
10/100/1000 Mbps link speeds. Two of these ports can be equipped with small form factor (SFP) transceivers
that support Fast (100Base-FX) and Gigabit Ethernet (1000Base-X).
The MES provides a configurable managed switch for use in subsea distribution units or Subsea Electronics
Modules (SEMs). Interchangeable fiber optic transceivers allow for port configuration as low-power optical links
to tie-ins and other subsea nodes or as high-power optical links to the surface via long optical umbilical cables.
Complete redundancy can be achieved using multiple cards within a distribution unit or SEM. Redundancy
protocols supported by the MES include MRP (Media Redundancy Protocol) and RSTP (Rapid Spanning Tree
Protocol).
Advanced diagnostics provide real time health monitoring of the system and include optical SFP information,
temperature, voltage, current, humidity, Ethernet link status, and Ethernet switch configuration. The MES
provides diagnostics access via Telnet and Modbus TCP.
Focal’s subsea qualified fiber-optic SFP transceivers are recommended for use with this board. Options available
include bidirectional transceivers and CWDM transceivers with support for 50 km, 100 km and up to 200 km
range.
Figure 1-1: Model 922-MES
The following features and processes are used to ensure reliability and increase product life:
Conductive cooling and detailed thermal analysis
Advanced diagnostics and health monitoring via Modbus TCP
Use of industrial temperature range electronic components
No fuses, electrolytic or tantalum capacitors
Environmental stress screening

3.1 Example Optical Topologies
The Ethernet switch-based architecture and the configuration adopted for the 922-MES can be used to satisfy
a number of different subsea operational requirements.
For example, more than one MES Ethernet modem can be used to provide full card redundancy. Alternatively,
configuring each card to connect to separate copper Ethernet devices provides additional throughput capacity.
Lastly, connecting a copper Ethernet channel between two modems (i.e. electrically daisy-chaining the second
card), can provide a second pair of optical connections for other subsea nodes. With RSTP functionality enabled
in the MES the copper ports can also be used to electrically daisy chain multiple cards using multiple copper
ports. The figures below illustrate some alternative optical topologies supported by this modem.

4.0 Configuration
On power up, the 922-MES starts a boot-up sequence that includes hardware and software initialization of the
Ethernet switching functions. This initialization period typically takes about 1.5 minutes and during this time all
Ethernet ports are disabled. After this period the switch configuration is loaded from an EEPROM with factory
default settings which are listed in section 4.1. These default settings can be changed via any Ethernet port
using a Modbus or Telnet connection and also saved to the EEPROM by the user to accommodate specific
switch functions and network topologies.
MES cards with diagnostics firmware ≥0xA3 support saving the user’s switch configuration to EEPROM via
Telnet and Modbus. In addition to the standard boot-up process previously described, cards with uC DIAG FW
≥0xA3 have a second layer verification to ensure the MES core loads its configuration correctly. This layer of
verification consists of monitoring the MES core and ensuring the card boots-up correctly on power-up and that
the MES core operating system is running correctly. In the unlikely event that a failure is detected such that the
MES core cannot access the user EEPROM to load its configuration or the MES core stops responding, the card
will attempt to fix the problem on its own by self-rebooting (up to 3 times) and in where needed it will attempt to
re-load factory default backup switch configurations depending on the error detected. Note that error codes are
embedded in Modbus data and UDP heartbeat packets which are sent automatically by the card every 5 seconds
(factory default).
The MES card also includes a remote firmware upgrade feature which offers an upgrade path to support future
protocols or application specific requirements.
The card’s default Ethernet port settings are as follows:
Copper ports CU1-CU8 are 10BASE-T /100BASE-TX / 1000BASE-T with auto-negotiation and auto
MDI/MDI-X enabled.
SFP ports SFP1-SFP2 are 1000BASE-X.
Supported packet sizes are standard Ethernet frames (64-1518 bytes), Ethernet II type frame (1536
bytes), huge frames (1916, 2048 bytes) and jumbo frames (9000 bytes).
The configuration options for the card that are saved in non-volatile memory EEPROM include the following:
Ethernet Switch Settings
oLink speed, duplex and negotiation mode (per port)
oMRP mode (MRM or MRC) for SFP ports SFP1-SFP2.
oRSTP for copper ports CU1-CU8 (global)
Diagnostic Settings
oNetwork, IP configuration
oDHCP mode
oUDP heartbeat frame rate and type
oSerial diagnostics
Diagnostic interfaces to the card include Ethernet ports (any copper or SFP) for full diagnostics and control of
the board and a factory serial diagnostics interface via a 3.5 mm non-isolated RS-232 port which provides
basic read-only card configuration information and board status intended for factory bench testing.
The MES card is fully programmed at the factory (core, diagnostics, EEPROMs, etc.). MES core firmware options
are shown in the table below. By default the card is shipped with core firmware P/N: 922-1008-50 unless
otherwise requested or specified by the customer. The MES card’s diagnostics firmware (uC DIAG) P/N 922-
1008-00 is the same for both MES core FW options.

4.2 Initial User Setup
The card is fully operational with factory default settings shown in Table 4-2. The following settings are typically
reviewed by the end user and are changed as required depending on the network topology where the card will
be used.
SFP Port Mode of Operation (redundant or daisy chain):
MRP: ON / OFF
Mode: MRC / MRM
Note: In redundant operation (e.g. ring topology) where two MES cards can be connected together using both SFP ports, normally
MRP is ON with MRM mode at the surface card and MRP is ON with MRC mode at the subsea card. For daisy chain operation (two
SFPs active at the same time) the cards can be left in MRC mode or with MRP OFF.
SFP Media Type (link speed):
100BASE-FX / 1000BASE-X
Note: No changes are required for factory-provided SFPs. In cases where the end user installs third party SFPs, changes might be
required depending on the SFP type. It is highly recommended to use Focal approved SFPs to ensure reliable performance of the
card.
Network Settings:
Diagnostics
Factory reserved parameters
Note: Diagnostics is served by a microcontroller (uC DIAG) and provides access to all diagnostic options and management of the
card. The factory reserved parameters are intended for future use and could be used by a secondary microcontroller embedded in
the MES switch core.
4.2.1 Initial Card Configuration via Telnet
1. Connect a standard Ethernet cable between your PC and CU1 (or any other copper port) of the card under
configuration.
2. Power up the card (+24 VDC).
Note: The card boot-up time is about 1.5 minutes and on-board LEDs will indicate a physical link after this period of time. The user can
run continuous pings (IP: 192.168.0.100) to the card as a way to verify once a Telnet link can be established. By default, DHCP is
enabled and this might increase the time between power-up and initial ping responses.
3. Using a terminal emulator program, such as TeraTerm, establish a Telnet connection to the card using:
a. Host: 192.168.0.100
b. TCP Port #: 23
4. The “Model922 MES>” prompt will appear after a connection has been established. At this point Telnet
commands can be used to change and save new user settings. It is recommended to record the new settings
for future reference. Typical configuration options are shown below.

4.2.2 Initial Card Configuration via GUI
MES cards with diagnostics FW 922-1008-00 (uC DIAG) version ≥ 0xA4 can be configured using Focal’s sample
922-MES GUI P/N 922-0408-00. More details of the GUI are shown in the “Graphical User Interface (GUI)”
section of this document.
The card configuration procedure using the GUI is similar to the Telnet procedure. However, when using the
GUI the user should following steps.
1. Connect a standard Ethernet cable between your PC and CU1 (or any other copper port) of the card under
configuration.
2. Power up the card (+24 VDC).
3. Run the 922-MES GUI and follow the steps below in sequential order:
a. Add a new card configuration by clicking the top left corner “+” button (default factory diagnostics IP
address is 192.168.0.100).
b. Click the “Connect” button.
c. Click System Maintenance Boot Config Open Boot Config Editor. The “Model 922 Boot Config
Editor” window will appear.
d. Make the desired card configuration changes. E.g. SFP settings, MRP (if available), RSTP changes,
etc.
Note that in the “Model 922 Config Editor” window, changes made by the user will only take effect after
the “Save Configuration” button is pressed and after one subsequent power cycle.
To make experimental volatile changes (not saved in EEPROM) the “Ethernet Switch Settings” section
of the GUI should be used.
e. Click the “Save Configuration” button to save the new card settings to EEPROM.
f. Power-cycle one (1) time ONLY the card under configuration.
g. Wait for GUI reconnection.
h. Verify the card’s functionality and that the changes are as expected.
i. A GUI message will appear asking the user to confirm if the changes are ok.
i. If the user accepts the changes then the card will keep the new user configuration.
ii. If the user ignores the changes and does not confirm the changes via the GUI then the card will
revert to the last known configuration on the next power-cycle.
4. Change the diagnostics IP address via Telnet (if required) following the steps shown in the previous section
4.2.1 step 4c.
5. Power cycle the card for the changes to take effect.
6. (Optional) Reconnect with the GUI and then re-open the “Model 922 Boot Config Editor” window and click
“Export Configuration” to save a copy of the new user configuration to your local PC.
7. Done! The initial card configuration is completed.

The 922-5012-xx cards include a 922-0208-00 PCB assembly (PCBA) which is a standard 3U Eurocard form
factor of 100 mm x 160 mm.
This PCBA is designed for interfacing with a custom backplane in a Eurocard sub-rack (card cage) or wiring
harness using a 96-pin DIN 41612 connector. This connector provides the interface for power and eight (8)
copper Ethernet ports. On the front of the PCBA are two (2) SFP ports and a factory diagnostics port. Key part
locations are shown in section 6.1.
5.1 Card with Front Panel
Card P/N: 922-5012-98
This card includes a 4 HP front panel as shown in the figure below. This card will fit in a 4 HP wide slot (0.8 in
or 20.32 mm) in a 3U Eurocard sub-rack. The front panel covers the front end of the PCBA and includes a handle
to allow for ESD safe handling and installation via rack card guides. Front panel cutouts allow access to the SFP
ports and a factory diagnostics port. This PCBA also includes a heat plate for improved conductive heat
dissipation. The 922-5012-97 PCBA includes a code strip which is installed on the DIN connector and a 6HP
front panel (1.2 in or 30.48 mm). Note that SFPs are not included in the card assembly.

5.2 Card with No Front Panel
Card P/N: 922-5012-99
This card does not include a front panel and is intended for bolt down installation on a metal plate, in which case
a dedicated wiring harness is needed for connection to the DIN header. Top and front views of this card are
shown in the figure below.
Figure 5-2: Model 922-MES PCBA with No Front Panel
5.3 General Board Handling
The 922-MES PCBA does not require forced air convective cooling. Generally heat from the card is conducted
through the mounting hardware, such as metal standoffs, or via the front panel to rack connections. If the card
is intended to be used for extended periods beyond +40 C ambient, other heat dissipation or heatsink options
should be considered to extended product life. Contact the factory for more information.
Care must always be taken during the handling of PCBAs to ensure product integrity. The following guidelines
should be adhered to in working with PCBAs:
Always handle boards by the edges and do not touch any connector pins or other exposed interface
contacts.
Handle boards at an ESD safe workstation with a clean surface. Maintain ESD precautions during
installation.
Store each card in a separate, ESD protective package.
Do not flex boards during handling or when mounted. The mounting surface needs to be flat and even
such that the board is not flexed when bolted down.
Do not cause unnecessary shock and vibration, such as dropping or rough handling of the boards.
