UPGRADE
This action page is used to upgrade the embedded firmware of the EX1629. Prior to initiating the
firmware upgrade process, a new, uncompressed firmware image must be obtained from
VTI Instruments and be accessible from the computer that is connected to the EX1629. Unless
specifically noted by VTI Instruments, firmware upgrades do not alter the calibration or non-
volatile configuration settings (network configuration, time configuration) of the EX1629.
NOTE Do not power cycle the EX1629 during the firmware upgrade process. If power is lost during the
upgrade, the instrument may be put into an inoperable state, requiring return to the factory. An
uninterruptible power supply may be used to avoid this risk.
Perform the following steps to conduct a firmware upgrade:
1) Perform a Reboot or a power cycle.
2) Connect to the EX1629 via the embedded web page.
3) Click on the Upgrade link.
4) Click on the Browse button and select the firmware image file to be uploaded to the
instrument.
5) Click the Submit button to initiate the upgrade process.
The upgrade process takes approximately 5 minutes to complete, culminating with an automatic
instrument reboot. Once the reboot is complete, reconnect and confirm on the Index page that the
firmware revision level has been properly updated.
NOTE Due to the way in which the internal configuration state of the instrument is stored, digest values
for the factory default configuration, as well as digest values for saved configurations, may change
between firmware versions.
