WARNINGS, CAUTIONS, AND GENERAL NOTES
Safety Considerations
When installing or using this product, observe all safety precautions during handling and operation. Failure
to comply with the following general safety precautions and with specific precautions described elsewhere in
this manual violates the safety standards of the design, manufacture, and intended use of this product.
Emcore Corporation assumes no liability for the customer's failure to comply with these precautions.
Calls attention to a procedure or practice, which if ignored, may result in damage to the system or system component.
Do not perform any procedure preceded by a CAUTION until described conditions are fully understood and met.
Electrostatic Sensitivity
ESD = Electrostatic Sensitive Device
Observe electrostatic precautionary procedures.
Semiconductor laser transmitters and receivers provide highly reliable performance when operated in
conformity with their intended design. However, a semiconductor laser may be damaged by an electrostatic
charge inadvertently imposed by careless handling.
Static electricity can be conducted to the laser chip from the center pin of the RF input connector, and
through the DC connector pins. When unpacking and otherwise handling the transmitter, follow ESD
precautionary procedures including use of grounded wrist straps, grounded workbench surfaces, and
grounded floor mats.
Exposure to electrostatic charge is greatly reduced after the transmitter has been installed in an operational
circuit.

Emcore Corporation will not be responsible for loss of output or reduced output of opto-electronic
devices if the customer performs chip mounting, ribbon bonding, wire bonding, fiber coupling, fiber
connectorization, or similar operations. These processes are critical and may damage the device or
may affect the device's output or the fiber output.
Emcore Corporation test reports or data indicating mean-time-to-failure, mean-time-between-failure,
or other reliability data are design guides and are not intended to imply that individual products or
samples of products will achieve the same results. These numbers are to be used as management
and engineering tools, and are not necessarily indicative of expected field operation. These
numbers assume a mature design, good parts, and no degradation of reliability due to
manufacturing procedures and processes.
Emcore Corporation is not liable for normal laser output degradation or fiber coupling efficiency
degradation over the life of the device.

Chapter 2 INSTALLATION AND SETUP PROCEDURES
Introduction
This section contains information and procedures for installing the Model 10901G Power Supply, and for preparing it for
operation.
Unpacking and Inspecting the System
Unpack the system carefully; thoroughly inspecting the equipment to assure that no damage has occurred in shipment. If
damage is found, notify the responsible carrier and Emcore Corporation immediately.
Carefully check the contents of the shipment against the shipping list. Notify Emcore Corporation if there is an apparent
discrepancy.
Installing System Assemblies
Install each assembly in a standard NEMA 19-inch rack, with the10901G Power Supplies in the last two slots, (see fig 2-1).
Use an approved AC power cord UL listed (supplied with unit) to an AC outlet. Unit will accept both 110 and 230 VAC. Turn
switch on and verify LED’s to be ON.
This completes setup and installation procedures. The system is now ready for normal operation.

Chapter 3 OPERATION PROCEDURES
Introduction
The system normally operates without operator intervention. Periodic checking of LED voltage indicators will help keep the
system running without interruption. During normal operation, it is recommended to check the system every six hours.
LED Indicators
Visually monitor the following LED indicators. All should be on (green) whenever the system is operating.
+5V
+15V
-15V
If any indicator is off, the monitored item has either failed or operating parameters are outside specified limits. Refer to
Maintenance and Troubleshooting for maintenance procedures.
CAUTION
If the Laser Temperature indicator is off, disconnect the Transmitter Plug-In immediately to reduce the possibility of
further damage to the Transmitter.
Monitors and Alarms
It is the user’s responsibility to utilize monitor and alarm outputs provided on the system. Monitoring these outputs, and
logging readings periodically, will provide an early warning that maintenance is required to avoid system failure or
degradation.
