Replacing XRC-195 Board
The XRC-195 Board is mounted to the backside of access door. It is mounted, to the door,
on standoffs. Refer to Figure 4–1 or Figure 4–2.
The XRC-195 Board, as with any electronic board, is susceptible to
damage by static electricity or improper handling. To prevent this from
occurring, user should wear a grounding strap.
A grounding strap is a conductive device used to make connection
between the person handling the board, and a high quality ground point.
Before handling the board you must install ground strap on your body
then connect it to a grounded point. This discharges electrical static
buildup from the body to ground, preventing static from discharging to the
board.
Before removal of XRC-195 Board, be certain any data has been saved
to an external storage medium. Failure to do so could result in data loss
when XRC-195 Board is removed.
