Replacing the memory module, G1 HP D2D Backup Systems

NOTE: It is normally sufficient to replace the USB stick, leaving the existing cable in place.

See the previous section, if you are replacing the memory model in a G2 product.

1.Power off and remove the cover from the HP D2D, as described in the appropriate HP ProLiant Maintenance and Service guide, and locate the memory module (labeled 4 on the diagram).

2.Pull the failed memory module out of the USB connector (1) and simply plug in the replacement module.

3.If you need to replace the cable as well, first unscrew the bracket (2) holding the USB connector and then disconnect the cable from the motherboard (3). Replace the whole cable and tighten the screw on the bracket. Make sure both ends of the cable are connected securely.

4.Be sure to update the HP D2D software to the latest version. This is done from the Web Management Interface (Settings/Software page), as described in the HP StoreOnce D2D Backup System User Guide.

IMPORTANT: If your replacement flash stick is at a lower revision than the one it replaces, you may experience a message of “Devices Starting” or “Initialising". This message will also occur, if the D2D Backup System did not shutdown correctly. In this case, please wait a minimum of 12 hours before updating software.
