Physical Installation
If you have questions pertaining to the installation of AG 4800X/XS, please contact us at the numbers listed in the section
“
”. Our technical staff is always available for consultation, training, or service.
For More Information on...
•
the technical specifications for the AG 4800X/XS, refer to the chapter “
•
installing an openGear card and its rear module in the AG 4800X/XS frame, refer to the user guide for your openGear card.
Before You Begin
The AG 4800X/XS mounts in the rack frame by means of four rack screws fastened through the front mounting ears. This
should normally be sufficient to carry the load, including the weight of accompanying cables. However, in certain applications
such as mobile truck installations, it may be desirable to also support the rear of the frame. The optional Rear Support Bars and
Brackets are specifically engineered to compensate for extra load stress.

Static Discharge
Throughout this chapter, please heed the following cautionary note:
ESD Susceptibility
— Static discharge can cause serious damage to sensitive semiconductor devices. Avoid
handling circuit boards in high static environments such as carpeted areas and when
synthetic fiber clothing is worn. Always exercise proper grounding precautions when working on circuit boards and
related equipment.
Ventilation and Cooling
Your AG 4800X/XS frame was specially engineered to minimize internal heat buildup and thus improve card reliability.
For More Information on...
•
the power dissipation of individual openGear cards, refer to the user guide for your card.
•
replacing the cooling fan module, refer to the section “
Ventilation
For applications using less than 40W in a non-ventilated AG 4800X/XS, but where the individual card power consumption is
greater than 8W, the cards should be evenly distributed in the frame. This will prevent the creation of concentrated heat, or
unbalanced heat-rise areas, in the frame.
Notice
— For reliable performance, it is recommended that the AG 4800X/XS frame door not be opened for longer
than 5 minutes on frames loaded with more than 40W. For some extra high power cards, the door should not be open
for more than 1 minute.
Cooling Fan Module
The AG 4800X/XS frames come standard with a Cooling Fan Module installed in the frame door. The frame and 4800X-
OPT-1 can supply up to a maximum of 500W of card power, with 15W per card. Under these ventilated conditions, there
is no requirement for extra vertical spacing between the frames. The AG 4800X/XS frames can be stacked one on top of
the other, a feature that is highly desirable in densely crowded rack frame environments.
Caution
— The two sides of the AG 4800X/XS frame have perforations that are needed to ventilate the
power supplies and must not be blocked.
