Ethernet Operation
In order for the AMG system to transmit Ethernet signals, an onboard RJ45 Ethernet interface or
X16003 Ethernet interface adaptor should be fitted to both the Transmit unit and the Receive unit.
The Ethernet interface can operate at either 10Mbits/s half duplex, or 100Mbit/s full duplex, and data is transmitted from one port the other port with the minimum of delay or buffering. The maximum bandwidth (at 100Mbit/s full duplex) available for transmission across the fibre link is nominally
50MBit/s.
The 100BaseT port does not implement MDI/MDIX; it should be connected with a straight though cable to an external switch port and with a cross over cable when connected directly to a PC or DTE.

Mounting Details
The unit is designed to be mounted within an AMG2009 or AMG2015 Subrack on standard card guides.
Removal / replacement from / to the Case
Note: - The AMG unit PCB's are static sensitive. Handle with proper care and use normal electrostatic discharge (ESD) procedures. Use properly grounded protection (for example, wrist straps) when handling the PCB.
To remove units from the case to access the data expansion boards and the daughter boards, remove the 2 or 4 fixing screws on the rear panel and slide the PCB's out of the case.
Ensure that the fibres do not snag or get trapped.
To replace the PCB's into the case, slide the PCB's gently into the case aligning the boards with the appropriate slots. Ensure that the fibre do not snag or get trapped.
Safety
AMG Optical Fibre Products use Class 1 laser systems in accordance with EN 60825-2:2000.
It is always advisable to follow good practice when working with optical fibre systems. This includes:
Do not stare with unprotected eyes or with any unapproved collimating device at fibre ends or connector faces, or point them at other people.
Use only approved filtered or attenuating viewing aids
For other safety issues and advice on good practice associated with optical fibre systems, please see
EN 60825-2:2000 or your local safety officer.
Maintenance and Repair
There are no user serviceable parts within AMG products. See unit data sheet for full specification.
In case of problem or failure, please call your local support centre or contact: AMG Systems Ltd.
