Note: Refer to the respective ADC card user manuals to determine the maximum number of cards that can be installed in a shelf before exceeding the maximum heat dissipation density of the telco-style equipment rack configuration.

Figure 1-11shows a typical example of a CO equipment rack layout using HMS-318 List 3 shelves. The figure shows a rack with a fuse panel, eight HMS-318 List 3 shelves, each separated by a two rack space baffle with the remaining shelf space open. As the figure illustrates, baffles should be placed between each shelf to reduce the chimney heating effect (see “Air Flow Guidelines” on page 1-15for further information about cooling the HMS-318 List 3 shelf).

Outdoor cabinet applications require forced air to ensure proper cooling.
