QUICK START GUIDE: I/O Expansion Card
ESD Warning
This product can be damaged by electrostatic discharge
(ESD). When handling, care must be taken so that the
devices are not damaged. Damage due to inappropriate
handling is not covered by the warranty.
The following precautions must be taken:
• Do not open the protective conductive packaging until
you have read the following, and are at an approved
anti-static work station.
• Use a conductive wrist strap attached to a good earth
ground.
• Always discharge yourself by touching a grounded bare
metal surface or approved anti-static mat before picking
up an ESD-sensitive electronic component.
• Use an approved anti-static mat to cover your work
surface.
Card Set-up and Conguration
Once you are properly grounded, follow this sequence of
steps to properly set-up and congure Symetrix I/O cards in
your Radius 12x8 EX, Radius AEC, or Edge hardware.
First, make sure the unit is powered down. Next, you must
remove the lid. To do this, 3 Phillips head screws need to
be removed from the top of the frame. Slide the lid back
and then up when removing. There is a lip that holds the
front down to the chassis.
If your Radius 12x8 EX, Radius AEC, or Edge unit has
blank ller panels in the card slots, unscrew and remove
them by removing the two black screws located on the
outside of the frame.
To remove an installed card, rst remove the 2 stainless
steel screws that mount the card bracket to the card. These
screws are located on the inside.
Next remove the stainless steel Phillips head screw from
the top of the card. Gently pull the card up to disconnect
the 50-pin connector. The card is no longer attached to the
frame. Carefully remove the card from the chassis.
Remove the bracket for the I/O card by removing the two
black screws located on the outside of the frame. Unused
I/O card bays must have a blank ller panel installed when
operating a Radius 12x8 EX, Radius AEC, or Edge unit.
To install a new card, mount the bracket for the new I/O
card to the frame chassis using the two black screws
provided.
Next, align and feed the connectors on the I/O card through
the opening in the bracket and align the single screw hole
in the card with the stando󰀨 on the motherboard. Look
through this hole and align with the stando󰀨 and then,
carefully, apply an even downward pressure until you feel
the card seat into the 50-pin socket. You will likely need to
carefully move the board side to side to align the 50-pin
connector. Use one of the stainless steel screws provided
and mount the board to the stando󰀨. Do not over tighten
this screw. The 50-pin connector on the Symetrix I/O cards
should not be under any tension when properly installed.
Now, install and tighten the 2 remaining stainless steel
screws that mount the bracket to the card. This should
ALWAYS be the last step before replacing the lid.
Finally, replace the lid.
The IN, OUT, AEC and DIGI LEDs on the front of the Radius
12x8 EX, Radius AEC, or Edge frame will illuminate in
combination to indicate the card type installed. For example,
an IN illuminates to indicate an analog mic/line input card,
whereas IN and DIGI illuminate to indicate a digital input
card. The IN and OUT LED’s illuminate to indicate a analog
telephone interface card. If the card is installed properly, the
card type LED(s) will illuminate.
