Setting The T1/PRI Switches
NOTE: The system only reads the SW2 and LIU DIP switches when you apply power to the board or do a manual
reset. With power on, manually reset the board by inserting a slender object, such as a straightened-out
paper clip, into the small hole located between the Yellow and Syn LEDs on the front-edge panel. You can
also reset the board remotely from a video display terminal or personal computer. A reset causes a service
disruption.

Down Load PRI Code To Flash
The DXPRI card has internal software that resides in FLASH memory that you can up-grade from the DXP Plus‘
serial data port. You must set SW1–8 for down-load or for normal operation.
