Non-volatile memory clearing package for SpinetiX HMP100

Copyright SpinetiX S.A. 2010, all rights reserved.

1. Introduction
   ------------

The accompaining memory-clear.pkg file is a package to perform
clearing of user data from the non-volatile memories of SpinetiX's
HMP100.

The clearing method rewrites the locations where user data can be
stored with the hexadecimal pattern 0x5A and randomly re-reading to
check that the pattern has been effectively written. This is the
procedure recommended by the "NSA/CSS Storage Device Declassification
Manual (SDDM)" for flash memories. This manual is available at
http://www.nsa.gov/ia/_files/government/MDG/NSA_CSS_Storage_Device_Declassification_Manual.pdf.

2. Obtaining the package
   ---------------------

The package can be downloaded from SpinetiX at the following URL:

3. Clearing procedure
   ------------------

a. Download the memory-clear.pkg to your PC, save it somewhere in your PC.

b. Plug the HMP100 unit into the Ethernet IP network so that it is
   reachable from your PC.

c. Power up the unit.

d. From your PC open the web based administrative interface of the
   unit in a web browser (see HMP100 manual).

e. From the "Maintenance" menu, "Advanced" tab, restart the system
   into the recovery console (i.e. diagnostics mode).

f. Wait for the unit to restart in recovery mode, the LED should blink
   at a rate of four times per second.

g. From the PC connect to the web based recovery console of the unit,
   the URL address should normally be the same as used above. However,
   if the system is using the factory default settings and has a
   serial number below 001d50000ff0 the URL is different and should be
   one of http://192.168.1.11/ to http://192.168.1.29/.

h. Select the "Main" page from the menu at the top of the browser
   window.

i. Under the "Install new firmware" section click the "Browse..."
   button and select the memory-clear.pkg file downloaded above.

j. Click the "Upload and install this image" button.

h. Wait for the clearing process to complete, this should take about
   10 minutes.

If the process is successful all user data has now been cleared from
the unit but a system firmware needs to be re-installed to use the
unit again, as explained in the next section.

4. Making the unit operational again
   ---------------------------------

The above procedure clears the system firmware along with user data.
Hence the system firmware needs to be re-installed to make the unit
operational gain.

This can be done as follows.

a. Connect to the web based recovery console of the unit as explained
   above.

b. Select the "Main" page of the web based recovery console at the top
   of the browser window.

	     package file.
