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 green LEDs and the red LAN LED 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 red LAN LED flashes.
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 green LEDs and the red LAN LED 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 green LEDs flash, while the red LAN
LED is lit continuously.
The new firmware is extracted and configured. This procedure takes 1 to 3 minutes.
•
As soon as the procedure has been completed, the mGuard restarts.
The mGuard is in the delivery state. You can now configure it again (see "Establishing a
local configuration connection" on page 172):
After the restart, the mGuard pci is automatically assigned a management IP address.
This address is assigned by a BootP server that can be accessed on the network and was
used during flashing.
If the recommended DHCP server is also used for Windows (see page 258), it also oper-
ates as the BootP server. This does not apply when using a DHCP server under Linux.
