• (V 1.1)
Each frame comes standard with one PS-8300 power supply.
Optional Cooling Fans
The frame has been designed with an advanced cooling architecture to increase ventilation.
For applications where the total card load is less than 40 Watt, the 8321 can be used without cooling
fans. Frames should be mounted with 1RU empty space between frames.
For applications where frames are mounted directly above or below other equipment, or where the total
card power load is greater than 40 Watt, an optional cooling fan kit must be added. These front-door
mounted fans provide forced air cooling for all cards, and additional cooling for the power supplies. An
intelligent fan controller adjusts fan speed with changes in frame power loading. Particular attention
has been paid to frame acoustics in order to keep fan noise to a minimum.
Additional Frame Accessories
To help reduce mechanical stress due to cable weight, a rear frame support bracket (FSB-8321) is also
available.
Important
For long-term reliability and increased product lifespan, total
dissipation of all cards installed in a 2RU frame must not
exceed 40 Watt total without the use of the Cooling Fan
Module. Refer to the section, “Ventilation and Cooling,” in
this manual, for details.
