Power down the router. Insert the new CF card into the external CF slot, located beneath a small metal cover at the rear of the device. There is a small lever on the left side of the CF slot that is used to eject a CF card if one is already in place.

This is what you will see on the console when you insert the CF card:

ad2: Device does not support APM
ad2: 977MB <SanDisk SDCFH-1024 HDX 4.04> at ata1-master PIO4

Execute the following commands. When running ‘request system storage cleanup’, it is fine to answer ‘yes’ when prompted.

request system storage cleanup
request system snapshot partition media removable-compact-flash as-primary
request system reboot media removable-compact-flash

The router will now reboot off the new external CF card. If you are replacing the internal CF card, you will want to take the external cover off the router and move the external CF card into the internal CF slot. The internal CF slot is located at the front left of the device under a metal plate, secured by (4) screws.

The J2350 router has (4) DIMM slots. Upgrading the memory is as simple as replacing the existing memory with new memory. Although you can put 4 x 2GB memory in the router, it will only recognize 3811MB of RAM. This is normal.
