Replacing a RAM card in the G430

The G430 has a single RAM slot housing a 256 MB RAM card. If you wish to support an 
increased number of announcement files, you must upgrade the G430 memory by replacing the 
256 MB RAM card with a 512 MB RAM card.

The RAM slot is located on the G430 main board. You must remove the G430 cover to replace 
a RAM card. This procedure includes the following steps:

1.

Removing the G430 cover

2.

Replacing the G430 RAM card

 

3.

Replacing the G430 cover

1. Disconnect the G430 power cable from the mains power supply.

2. Disconnect all cables (data and power) connected to the G430 and its media modules, both 

front and rear. Note to which connector each cable is connected, so that you can reconnect 
them correctly.

3. Remove the G430 from the rack or wall, if it is wall or rack mounted.

4. If mounting brackets are attached to the G430, remove them.

5. Unscrew the eight cover screws, indicated by small arrows etched into the cover:

- Remove one screw from the top (see 

Figure 4

).

- Remove four screws from the right side (see 

Figure 5

6. Lift the cover off the G430.
