Maintenance and 
Modifications

This section provides procedures for maintaining and modifying the FOX3 matrix switchers, 
including:

• 

Mounting the Switcher

• 

Battery and Power Precautions

• 

FOX3 Matrix Replacement Cards

• 

Removing and Installing an I/O Module

• 

Removing and Installing a Power Supply Module

• 

Removing and Installing a Fan Assembly

ATTENTION:

• 

Installation and service must be performed by authorized personnel only.

• 

L’installation et l’entretien doivent être effectués par le personnel autorisé uniquement.

Mounting the Switcher

All FOX3 Matrix models are housed in rack-mountable, metal enclosures with mounting 
flanges for standard 19-inch wide racks.

UL Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the 
matrix switcher into a rack.

• 

Elevated operating ambient temperature

 — If the equipment is installed in a closed 

or multi-unit rack assembly, the operating ambient temperature of the rack environment 
may be greater than room ambient. Therefore, consider installing the equipment in an 
environment compatible with the maximum ambient temperature specified by Extron 
(Tma = +32 to +122 °F [0 to +50 °C]).

• 

Reduced air flow 

— Installation of the equipment in a rack should be such that the 

amount of air flow required for safe operation of the equipment is not compromised.

• 

Mechanical loading

 — Mount the equipment in the rack so that uneven mechanical 

loading does not create a hazardous condition.

• 

Circuit overloading

 — Consider the connection of the equipment to the supply circuit 

and the effect that overloading of the circuits might have on overcurrent protection and 
supply wiring. Use appropriate consideration of equipment nameplate ratings when 
addressing this concern.

• 

Reliable earthing (grounding)

 — Reliable earthing of rack-mounted equipment 

should be maintained. Particular attention should be given to supply connections other 
than direct connections to the branch circuit (such as the use of power strips).
