Problems While Upgrading the CN2A
Problem
Solution
You are planning to use the SmartSystems
Console to upgrade an older CN2A, but
you cannot find an icon representing
your CN2A in the Console.
Try these solutions in order:
• Click the
Discover
button to refresh the Console
display.
• Make sure the CN2A is turned on.
• Make sure that you have a good RF connection.
For help, see “Problems With Wireless
Connectivity” on page 102.
• An older CN2A may not have the SmartSystems
client installed on it. Use the SD card to upgrade
the CN2A OS and DOC files, and then check to
see if the CN2A appears in the Console.
While using the SmartSystems Console
to upgrade the OS, the dots stopped
moving in the “Upgrading...” message on
the CN2A screen and the screen appears
frozen.
The upgrade has failed. Go to the Event Viewer in
the Console and review the messages:
• If you see the message, “File not found,” you
changed the default directory when you used the
InstallShield application to extract the upgrade
files to your PC. You need to extract the upgrade
files again and accept the default directory. For
help, see “Using the SmartSystems Console to
Upgrade the CN2A” on page 115 or “Using an
SD Card to Upgrade the CN2A” on page 118.
• If you see the message, “Failed to copy to device”
or if you see no error message, your RF
connection to the network may not be strong
enough. For help, see “Problems With Wireless
Connectivity” on page 102.
While using the SmartSystems Console
to upgrade only the DOC files, the dots
disappeared from the “Upgrading...”
message on the CN2A screen and the
screen appears frozen.
There is no problem. This screen will appear frozen,
with no dots visible, for at least one minute while the
DOC files are copied to the CN2A. Eventually, the
CN2A desktop will appear.
After upgrading only the DOC files,
nothing seems to have changed on your
CN2A. The old DOC files are still active.
When the DOC files only upgrade is complete, and
the CN2A desktop appears, you must cold boot the
CN2A to activate the new DOC files.
For help, see
“Cold Booting the CN2A” on page 112.
