Component replacement
S8300 and G700 component maintenance
Reasons for replacing a Media Module include:
• Repairing a damaged Media Module
• Changing Media Module type
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 <#> 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,
555-233-200.
!
The G700 must not be operated with any slots open; empty slots should be covered with the
supplied blank plates.
CAUTION:
The connector pins can be bent or damaged if the module is handled roughly or if
misaligned and then forced into position.
CAUTION:
Separate ESD paths to the chassis ground connect to the Media Modules at the spring-
loaded captive screws. Ensure the captive screws are securely tightened to prevent damage
to the equipment.
Replacing Avaya Media Modules
1 Identify and mark all cables.
2 Undo the cables.
3 Undo 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
page 301)
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.
