Hardware Installation

This section describes the tasks needed to install the DEFINITY LAN Gateway system hardware and peripheral hardware.

The DEFINITY LAN Gateway system installation tasks are the same for all switch types. These tasks include:

Task 5: Install the DEFINITY LAN Gateway system assembly

Task 6: Connect the Alarm Board cables

Task 7: Install the terminal (optional)

Task 8: Connect the Maintenance Modem

Task 9: Finalize and test the hardware

Before beginning these tasks, refer to the following worksheets:

Appendix A, PBX Carrier Configuration Worksheets

A-1, Port Slot Assignments (Before Carrier Rearrangement)

A-2, Port Slot Assignments (For Carrier Rearrangement)

A-3, Port Slot Locations for the DEFINITY LAN Gateway System

Assembly

Appendix B, Supported Terminals and Modems/Option Settings

B-1, Terminals/Modems

Task 5: Install the DEFINITY LAN Gateway

System Assembly

This task is required for all installation scenarios.

WARNING:

To prevent damage to the DEFINITY LAN Gateway system assembly, make sure that you (or the factory, for new switches) have connected the system assembly adapter cables to the port connectors on the back of the switch (as described in Step 3) before you insert the system assembly in the switch carrier.

You can install the system assembly in the switch when the switch is powered on or off. When the assembly is inserted in the slots of the switch carrier, it will automatically power up, run diagnostics, and boot. To avoid a disk crash, never remove the assembly without first completing the shutdown procedure to shut down the DEFINITY LAN Gateway system (and allowing the disk to completely spin down).
