Installing A Module; Before You Begin; Required Equipment; Static Discharge - Ross ULTRIX-MODX-IO User Manual

Installing a Module

Installing a module into an ULTRIX-MODX-IO blade in an Ultrix router requires you to remove the
blank plate in the required blade slot, install the required module into the blade, and then install
the required SFP modules into the required port(s). The procedure for installing a module is the
same for all module and router types.
 A single ULTRIX-MODX-IO blade can accommodate up to four modules.
If you have questions pertaining to the installation of the module, contact us at the numbers listed
in "Contacting Technical Support". Our technical staff is always available for consultation, training,
or service.

Before You Begin

Ensure the ULTRIX-MODX-IO blade is installed in the Ultrix router. Refer to "Installing the
ULTRIX-MODX-IO" for details.

Required Equipment

The following equipment is required:
• the I/O module to be installed in the ULTRIX-MODX-IO blade
• a #1 Phillips screwdriver

Static Discharge

Throughout this chapter, please heed the following cautionary note:
ESD Susceptibility
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.

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.

Installing a Module into the ULTRIX-MODX-IO Blade

When a blade slot is not populated with a module, a blank plate must be installed to protect the
chassis interior and ensure proper cooling. When installing the module into an unpopulated slot of
the ULTRIX-MODX-IO blade, you must first remove this blank plate from the slot.
