Avaya S8300 Series Replacement Manual page 61

The modules on the G700 are not inserted until the G700 registers with Communication
Manager. Likewise, all Media Modules and associated Maintenance Objects are removed if the
G700 link goes down. The term 'board insertion process' refers to the process in which the
Media Modules are queried as to their type, suffix, and vintage. Use the list config all or
list config media-gateway number commands to access this information. Any Media
Module that does not agree with administration generates a process error and is flagged to the
relevant administration form. The removal of the Media Modules is detected. Listings of the
G700 circuit packs show the relevant slot location as having 'no board.' The determination of
T1/E1 modes of operation for the DS1 Media Modules is downloadable, since the DS1 Media
Module can function as either a T1 or E1 interface.
Upon Media Module replacement, modules are registered with the G700 Media Gateway,
where board type, suffix, and vintage are verified. The G700 then sends appropriate H.248
messages to the controller, thus creating Communication Manager objects.
For detailed descriptions of the Media Modules see Hardware Guide for Avaya Communication
Manager, 555-245-207.

Replacing Avaya Media Modules
1. Identify and mark all cables.
2. Remove the cables.
3. Loosen the captive screws and slide out the old Media Module.
4. Position the Media Module squarely before the selected slot on the front of the G700
chassis and engage both sides of the module in the interior guides.
5. Slide the module slowly into the chassis, maintaining an even pressure to assure that the
module does not become twisted or disengage from the guides
Modules on page 58).
6. Apply firm pressure to engage the connectors.
The Media Module connector has different length pins. The long pins will engage first to
provide grounding. Medium length and short pins will provide power and signal.
