2.7.5.3 Connector Pin-Outs on BRIU Blade
2.7.5.4 To install a BRI Interface Blade:
1. Set the SW1 and SW2 jumpers on the BRI blade for either T-Bus or S-Bus.
2. Set the SW1 and SW2 TR jumpers as either terminated or unterminated.
3. 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.)
4. Plug the BRI blade into the system chassis.
5. 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.
6. Connect the cable from the NT1 Network Termination cable to the CN7 or CN8 connector on
the BRI blade and/or BRI daughter board.
