Chapter 2 Installation Installation Overview There are several stages involved in the installation of the M15-155: • Module Installation: Inserting the module in the Avaya M770 chassis and connecting cables to the module’s ports for connection to other equipment such as a switch or station. • Command Line Interface (CLI): Connecting a terminal to the local console to access the CLI and configuring all parameters.
Chapter 2 Installation Laser Classification Note: Class 1 lasers are inherently safe under reasonably foreseeable conditions of operation. Caution: The use of optical instruments with this product will increase eye hazard. Usage Restriction The optical ports of the module must be terminated with an optical connector or a dust plug when not in use.
Chapter 2 • Installation While holding the module by its handles, place it onto the top and bottom guide rails in the chassis and gently slide it in by pressing in the middle of the module. The module should slide in smoothly. Caution: Ensure that the metal edges of the card (not the PCB) are aligned with the guide rails. Align the bottom edge first and then the top edge since the module slots in the bottom rail before the top rail.
Chapter 2 Installation Power-on Check When you plug in the M15-155, wait until first the CPU LED lights and then the OPR lights steadily before commencing work. If there are several M15-155 modules, one module will be elected as the Master Agent, and the NMA LED on that module will also light ON. For a detailed explanation of the Master Agent please refer to the Avaya M770 ATM Switch User’s Guide.
