Flashing the firmware/rescue procedure
The entire firmware of the mGuard should be reloaded on the device.
–
All configured settings are deleted. The mGuard is set to the delivery state.
–
In Version 5.0.0 or later of the mGuard, the licenses installed on the mGuard are re-
tained after flashing the firmware. Therefore, they do not have to be installed again.
The administrator and root password have been lost.
NOTE: To flash the firmware, a DHCP and TFTP server or a BootP and TFTP server must
be installed on the locally connected computer.
Install the DHCP and TFTP server, if necessary (see "Technical data" on page 253).
NOTE: Installing a second DHCP server in a network could affect the configuration of the
entire network.
NOTE: Do not interrupt the power supply to the mGuard during any stage of the flashing
procedure. Otherwise, the device could be damaged and may have to be reactivated by
the manufacturer.
•
Hold down the Reset button until the 1, 2, and V.24 LEDs light up. Then, the mGuard is
in the recovery state.
•
Release the Reset button within a second of entering the recovery state.
If the Reset button is not released, the mGuard is restarted.
The mGuard now starts the recovery system: It searches for a DHCP server via the LAN
interface in order to obtain an IP address.
The 1, 2, and V.24 LEDs light up orange.
The "install.p7s" file is loaded from the TFTP server or SD card. It contains the electron-
ically signed control procedure for the installation process. Only files that are signed are
executed.
The control procedure deletes the current contents of the Flash memory and prepares
for a new firmware installation.
The 1, 2, and V.24 LEDs form a running light.
The "jffs2.img.p7s" firmware file is downloaded from the TFTP server or SD card and
written to the Flash memory. This file contains the actual mGuard operating system and
is signed electronically. Only files signed by Innominate are accepted.
This process takes around 3 to 5 minutes. The 1, 2, and V.24 LEDs are off, the P1, P2,
and STATUS LEDs light up continuously green.
The new firmware is extracted and configured. This procedure takes 1 to 3 minutes.
•
As soon as the procedure is complete, the 1, 2, and V.24 LEDs flash green simultane-
ously.
•
Restart the mGuard. To do this, briefly press the Reset button.
The mGuard is in the delivery state. You can now configure it again (see "Establishing a
local configuration connection" on page 247):
