SMX System MultiMatrix Switcher • Setup Guide
This setup guide describes basic instructions for the set up of the Extron SMX System MultiMatrix switcher. The SMX matrix switcher
can be controlled via the front panel controls, Simple Instruction Set (SIS
™
) commands, or the SMX Control Program.
The 2U frame has 4 single board slots, the 3U frame has 6 board slots, the 4U frame has 8 slots, and the 5U frame has 10 slots. Each
slot supports power and control connections to the I/O boards. When a board is installed into a slot, it may use more than one slot.
The slots that a board covers are not available for other I/O board installation until that multi-slot board has been removed
This guide provides instructions for an experienced installer to set up and operate the SMX System MultiMatrix Switcher. For full
installation, configuration, and operation details, see the SMX System MultiMatrix Switcher User Guide available at www.extron.com.
UL Safety Requirements
Make sure to follow the safety requirements listed below for a safe installation and operation:
1. Do no use the switcher near water.
2. Clean only with a dry cloth.
3. Do not block any ventilation openings. Install in accordance with the manufacturer instructions.
4. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including
amplifiers) that produces heat.
5. Do not defeat the safety purpose of either the polarized or grounding type plug.
A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third
grounding prong. The wide blade or the third plug are provided for the installer’s safety. If the provided plug does not fit
into the outlet, consult an electrician to replace the obsolete outlet.
6. Protect the power cord from being walked on or pinched; particularly at plugs, convenience receptacles, and
the point where they exit from the apparatus.
7. Only use attachments/accessories specified by the manufacturer.
8. Only use the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
9. Unplug this apparatus during lightning storms or when unused for long periods of time.
10. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been damaged in any way, such as the power-supply cord or plug is
damaged, liquid has been spilled, or has been dropped.
Installation Steps
Step 1 — Mounting and Installing I/O Boards
Turn off all of the equipment and disconnect it from the power source. Mount the switcher; the unit can be securely mounted in a
rack space using optional Extron Mounting Brackets and accessories (see the Extron website for compatible optional mounting
accessories) or on top of a table using the included self-adhesive rubber feet. Neither the brackets or rubber feet come attached to the
matrix switcher.
IMPORTANT:
Go to www.extron.com for the
complete user guide, installation
instructions, and specifications.

Rack Ear Mounting
To rack mount the SMX, use two screws on each end of the switcher to attach it to the rack mount (see figure 1 below).
Figure 1. Mounting the SMX Matrix Switcher
Installing I/O Boards
The I/O boards on any unit may vary with each installation, depending on desired configuration and use. Each board has input and
output connectors that are clearly marked, and a 16-position rotary switch used to set the I/O plane address.
NOTES:
• The boards are hot-swappable meaning they can be installed or removed without turning off or disconnecting the
power. However, turning the power off prior to installing or removing boards is recommended.
• Use ESD precautions when installing a board to avoid damaging it. Keep the board in the anti-static bag until needed.
Use proper grounding techniques during installation.
Installing new boards into an empty SMX frame
1. Remove as many blanks plates from the rear of the unit as needed.
2. When ready, remove the board from the anti-static bag, taking
care not to touch any of the components on the board. Slide
the board into the open rear slot (see figure 2 to the right),
carefully aligning it with the plastic slides in the frame. Push the
board firmly into place.
3. Tighten down the screws on each end of the board.
NOTE: Use a tool to fully tighten the screws after initial
installation and subsequent removal and replacement
of the boards.
4. Repeat steps 1 through 3 for all boards needing installation.
NOTE: If the unit is connected via RS-232 or RS-422, it
responds with Reconfig when a board is installed or
replaced.

Replacing an existing I/O board
1. Remove any input and output cables for the I/O board being replaced.
2. Loosen the outer screws on the existing board and remove it from the unit.
3. Slide the replacement board firmly into place and tighten down the screws.
4. Repeat for all boards to be replaced. Any new boards are now ready for cabling.
Set Up Recommendations
Excessive heat can decrease a switcher’s lifetime. If installed in an eclosed or multi-unit rack assembly, the ambient temperature
can exceed the room’s temperature. It’s recommended to the install the SMX System MultiMatrix Switcher in an environment that is
compatible with the maximum ambient temperature of +122 °F (+50 °C).
To minimize the chances of overheating, the switcher should be installed in a rack so air flows freely and the equipment is not
compromised. Mounting on a rack also avoids dangerous conditions due to uneven mechanical loading.
Consider the effect circuit overloading can have on overcurrent protection and supply wiring. Be sure to connect the switcher to the
supply circuit.
And finally, pay attentiion to supply connections besides direct connections to the branch circuit, such as the use of power strips. It is
important to maintain reliable grounding of rack mounted equipment.
