EP-6CXA2C Form-Factor
The EP-6CXA2C is designed with ATX form factor - the latest industry
standard of chassis. The ATX form factor is essentially a Baby-AT baseboard
rotated 90 degrees within the chassis enclosure and a new mounting configura-
tion for the power supply. With these changes the processor is relocated away
from the expansion slots, allowing them all to hold full length add-in cards.
ATX defines a double height aperture to the rear of the chassis which can be
used to host a wide range of onboard I/O. Only the size and position of this
aperture is defined, allowing PC manufacturers to add new I/O features (e.g.;
TV input, TV output, joystick, modem, LAN, audio, etc.) to systems. This will
help systems integrators differentiate their products in the marketplace, and
better meet your needs.
• By integrating more I/O down onto the board and better positioning the
hard drive and floppy connectors material cost of cables and add-in cards is
reduced.
• By reducing the number of cables and components in the system, manufac-
turing time and inventory holding costs are reduced and reliability will
increase.
• By using an optimized power supply, it's possible to reduce cooling costs
and lower acoustical noise. An ATX power supply, which has a side-
mounted fan, allows direct cooling of the processor and add-in cards
making a secondary fan or active heatsink unnecessary in most system
applications.
