Installing the 6-Slot Rackmount/Desktop Chassis  
Install the chassis first before installing any modules into a 6-Slot Rackmount/Desktop Chassis.   

When installing the chassis, be sure to observe the following precautions to prevent electrical 
or mechanical damage: 

1.  Protect the chassis from exposure to sunlight and electrical or magnetic fields. 
2.  Ensure that the equipment rack remains stable, even with the addition of the chassis and 

its associated cabling. 

To install a 6-Slot Rackmount/Desktop Chassis: 
1.  Have four #10 screws and four clip nuts available (hardware may vary depending on 

rack type).  The rest of the hardware is supplied with the unit.  

2.  Locate a suitable location in the rack for installation and secure the clip-nuts onto the 

mounting rails.  Use screws to attach the chassis to the rack.   

3.  Plug the chassis into a reliable, filtered power source. 
4.  Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, 

the operating ambient temperature of the rack environment may be greater 
than room ambient. Therefore, consideration should be given to installing the 
equipment in an environment compatible with the maximum ambient 
temperature (Tma) specified by the manufacturer.  

5.  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.  

6.  Mechanical Loading - Mounting of the equipment in the rack should be such 

that a hazardous condition is not achieved due to uneven mechanical loading.  

7.  Circuit Overloading - Consideration should be given to the connection of the 

equipment to the supply circuit and the effect that overloading of the circuits 
might have on over current protection and supply wiring.
