Use this procedure to replace media modules in the G450 and G430 gateways. Before replacing any media modules, ensure that you know which are hot-swappable (see Hot swapping media modules).
Procedure
Identify and mark all cables.
Remove the cables, making note of the order in which they are removed.
Undo the captive screws and slide out the media module currently inserted into the G450 and G430.
Position the media module squarely before the selected slot on the front of the G450 and G430 chassis and engage both sides of the module in the interior guides.
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.
Apply firm pressure to engage the connectors at the back of the chassis.
The media module connector has different length pins. The long pins engage first to provide grounding. Medium length and short pins provide power and signal.
Lock the media module into the chassis by tightening the spring-loaded captive screws on the front of the module.
Re-connect the cables in the correct order.
Warning:
To prevent access to electrical hazards by unauthorized personnel and to ensure continued compliance to international radiated emissions requirements, all captive screws must be securely tightened such that they cannot be loosened without the use of a tool.
