2 The flash memory module

Overview

The flash memory module is required to boot up the HP D2D Backup System.

With HP D2D4324/4312 Backup Systems, this consists of a USB flash stick that plugs into the system board.

With all other HP D2D Backup Systems, this consists of a USB flash stick and cable.

There are different memory sticks for G2 and G1 products. Make sure you are using the correct one. See Identifying G1 and G2 products (page 6).

Part number

Each software revision has its own part number. Please refer to http://www.hp.com or contact HP Support to find out which part number is required.

Identifying a flash memory module failure

Symptoms of problems with the memory module are:

The system hangs

Hosts cannot connect to the HP D2D Backup System via the Web Management Interface

Troubleshooting procedure

1.If it is not already connected, connect the system console to the HP D2D Backup System.

2.Power cycle the HP D2D Backup System.

3.The HP D2D will attempt to boot from the flash memory module. The flash memory module is at fault, if the reboot fails with the following message: “Cannot find any bootable media” or if the system fails to boot completely or if it attempts to PXE boot.

4.Power off the system, remove the cover and check the cabling on the flash memory module. If this does not remedy the problem, replace the flash memory module.

Replacing the memory module, G2 HP D2D Backup Systems only

NOTE: The memory module for the HP D2D4324 and HP D2D4312 model consists of a USB flash stick. The memory module for the other G2 models consists of a flash stick with cable. It is normally sufficient to replace only the USB stick, leaving the existing cable in place.

See the next section, if you are replacing the memory model in a G1 product.

1.Power off the system and remove the cover from the HP D2D, as described in the appropriate HP ProLiant Maintenance and Service guide. Locate the memory module (labeled 1 on the diagrams below).

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

3.HP D2D4112/4106 and HP D2D2502/2504 models only: 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.

NOTE: The memory module for the HP D2D4324/4312 model does not have a cable.
