ULTRIX-MODX-IO User Guide (v1.0) Populating an SFP Port • 29
Populating an SFP Port
This chapter outlines how to populate an AUX port on the ULTRIX-MODX-IO blade or an SFP port on
a module.
For More Information on...
• installing an SFP module, refer to the documentation that accompanied your SFP module.
• the SFP modules supported by the router, refer to the Ultrix SFP Module User Guide.
• cabling the ports on the ULTRIX-MOD-SFP, refer to “ULTRIX-MOD-SFP”.
Static Discharge
Throughout this chapter, please heed the following cautionary note:
Working with Fiber Optic Connectors
Keep the following in mind if the SFP module(s) installed in a port includes a fiber optic connector:
• Every time you are required to insert a connector into a device or mating sleeve, you must clean
the connector. All exposed surfaces of the ceramic ferrule must be clean. Follow your facility
practices of cleaning fiber optic connectors.
• Connectors must always be inserted into a device or have a dust cap on.
• A poor optical connection is often similar to a poor electrical connection. Try removing the
connector, cleaning, and re-inserting the connector. A bad connection can result in experiencing
instability of signal, high loss, or a noisy signal.
Populating a Port with an SFP Module
This section provides a general overview of how to install an SFP module into an available port of
the ULTRIX-MODX-IO blade or ULTRIX-MOD-SFP.
An SFP module can only be installed in the AUX A or AUX B ports in the ULTRIX-MODX-IO blade.
The AUX C and AUX D ports are reserved for future use.
To install an SFP module in a port
1. Remove the dust cap from the port on the ULTRIX-MODX-IO or ULTRIX-MOD-SFP as follows:
a. Locate the port you wish to install the SFP module into.
b. Grasp the cap between your thumb and forefinger and gently press on the sides.
c. Pull the cap towards you and away from the port.
d. Store the dust cap for later use.
ESD Susceptibility — Static discharge can cause serious damage to sensitive semiconductor
devices. Avoid handling circuit boards in high static environments such as carpeted areas and when
synthetic fiber clothing is worn. Always exercise proper grounding precautions when working on circuit
boards and related equipment.
Caution — Do not remove the dust caps from the port until you are ready to install the SFP module.
