SerVision MVG 400 System Guide
Upgrading the Firmware 163
Upgrading the Firmware
From time to time, SerVision releases new firmware versions for the MVG 400. Firmware for
the video gateway component of the unit is distinct from firmware for the router component
of the unit, and updates are released for each at different times.
Upgrading Video Gateway Firmware
This section explains how to obtain and install new MVG 400 firmware. New firmware can
be installed on-site or remotely. It is recommended to install it on-site whenever possible. If
your distributor has a
TVG Upload Server to which you can connect, you can upgrade the
firmware using the configuration utility. Otherwise, you must download the firmware from
the SerVision website and use the
TVG Download Utility to download it to the MVG 400 .
NOTE: Upgrading the firmware does not change any of the unit’s settings.
CAUTION: If the download process is interrupted in any way before it is completed, or if
an incompatible firmware version is loaded, it may be impossible to connect to
the unit in the normal way again. Make sure that you know in advance that you
are loading the right firmware, and DO NOT INTERRUPT THE DOWNLOAD
PROCESS once it is started.
If it nevertheless becomes impossible to connect to the unit after an attempt to
upgrade the firmware, the Catch Boot option can be used to reconnect to the unit
and download the firmware to it again. See Catch Boot Option, page 168.
Upgrading Firmware via a TVG Upload Server
If your distributor has a TVG Upload Server to which you can connect, you can upgrade the
firmware using the configuration utility. Before you begin, ask your distributor for the IP
address or hostname of the server and its port.
