Set the SW1 and SW2 jumpers on the BRI blade for either T-Bus or S-Bus.
Set the SW1 and SW2 TR jumpers as either terminated or unterminated.
If a BRI daughter board is to be used, set the switches on the daughter board and connect it to
the BRI blade. (Refer to 2.7.6 BRI (2BRIDB) Daughter Board - P/N 0911050.)
Plug the BRI blade into the system chassis.
Before proceeding to Step 7, wait to verify that the STATUS LED starts to flash.
●
With normal operation, the status LED will flash fast. If trouble was found during the self
diagnostics routine, the status LED will flash slow.
●
Once connected, the ISDN Layer Link Status LEDs will not indicate the status of the
Layer 1 link.
Connect the cable from the NT1 Network Termination cable to the CN7 or CN8 connector on
