For applications where other types of I/O connections are necessary (such as twisted-pair audio or fiber
interfaces), the frame also supports slot-dependent rear modules. Rear modules can be ordered with
cards, and are easy and quick to install.

Robust Power Supplies
The 8310 frame can accommodate two front-loaded PS-8300 power supplies. Although a single power
supply can fully power a loaded frame, the addition of a second (optional) power supply gives the
frame full power redundancy. Each power supply is fed by a separate power cord, which is held in
position to guard against accidental power loss.

Each power supply contains an independent cooling fan, status LED, and a front-mounted power
switch.

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 8310 can be used without cooling
fans. Frames should be mounted with 1RU empty space between frames.
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.

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.
