24 System
Managing Security
Secure Erase All Function
Preliminary Procedure (Non-secure Area)
Perform this procedure once on the N8201A prior to placing it into a secure area, and
every time the instrument has been calibrated or repaired.
1 Record the Ethernet Number of the instrument. Press System, More, Show System. The
Ethernet Number is a 12-digit alphanumeric string with a hyphen between the first and
last set of six characters; for example, 001083-b80c55. Having this number recorded will
save time when you re-install the firmware into the instrument using the
“Re-installation of Firmware Procedure.”
2 Record the IP Address of the instrument. Press System, Config I/O. This address may
be changed by someone using the instrument in the secure environment, but at least
you will have documented what it was.
3 Obtain a list of the License Keys by saving a screen capture of the instrument’s
Licensing screen. Even though the next section tells you how to backup these keywords
to a PC, the PC may not be available when you need it. Press System, More, More,
Licensing, Show License. Use the file manager to save an image of the screen to a
formatted disk. Insert the disk in the front panel disk drive and press File, Save, Type,
Screen, Format, Bitmap and select Directory A. Press Save Now. The file can be
displayed or printed from any application capable of reading bitmap (.bmp) files. Before
proceeding, verify that the screen capture of the License Keys has been properly saved
to the disk by opening the file using a PC.
The licensing information can also be printed if the N8201A is connected to a printer. As a
last resort, write down the Option number and License Key for each option.
Properly store the License Key data, since it will be needed to recover the instrument.
CAUTION
Secure Erase All will render the instrument inoperable. All instrument settings
under System, Config I/O, such as the LAN address or gateway address will be lost.
All instrument option License Keys, such as those that enable the optional
preamplifier or measurement personalities, will be lost.
The following procedure outlines how to prepare prior to executing Secure Erase
All, and how to recover the instrument following the Secure Erase All.
Be sure to back up the instrument configuration and option keyword information via
LAN using the N8201A Series Firmware Upgrade Program before the instrument is
placed in the secure area.
