3.13 Installing and Removing Modules
3.13.1 Configuration Rules
These rules limit the total power dissipation of modules that can be installed in the box and
use the module power ratings to calculate the total power dissipated in the enclosure.
3.13.1.1
Module Power Rating
The power rating for each module will be given in the associated operation manual for that
module or in the product technical specification available on the Snell Web site.
3.13.1.2
Available Power
The IQH3A IQ 3U Modular Enclosure has 141 Watts of available power. The Power Ratings
of each module should be added together and the total should not exceed 141 Watts.
Modules that do not specify a “Power Rating” should use the total power figure as a power
rating value.
3.13.1.3
Power Rating Table
This table can be used to calculate and check the available and used power units within the
enclosure.
Before installing a new module into the enclosure. Ensure that the configuration rules given
below are followed.
The rear of the enclosure must have a full compliment of rear panels. Any vacant slots
must have a blank rear panel fitted.
The sum of the module power ratings (calculated using the method above) in the enclosure
must not exceed 141 Watts.
