Troubleshooting
Page 62
Cause:
Physical network issue(s).
Solution:
Verify that all network devices are properly connected and powered up. Follow the cables,
make sure they are plugged into the correct connectors, and check every connector thoroughly.
Cause:
Network configuration issue(s). To establish an IP connection, the unit and the browsing PC
must be on the same subnet. DHCP is disabled by default on the unit. It has a factory-set IP address
in the 10.x.x.x range.
Solution:
Install Device Manager, a software tool available for download at http://siqura.com, on
the browsing PC. Scan the network with Device Manager. If the unit is not detected, set the network
adapter of the PC to the factory-set subnet of the unit. The IP address is printed on a sticker on the
unit. Use Device Manager or a browser to access the unit from the PC, and then modify its network
configuration as needed.
Cause:
Security issue(s). The connection is blocked by a firewall.
Solution:
Check if there is a firewall on the PC or on the network which is blocking the connection.
Contact your system or network administrator for assistance, if necessary.

Upgrade issues
Successful upgrades are reported as "Successfully upgraded to version ...". In the event of an
unsuccessful upgrade, the following error messages may help you pinpoint the cause of the
problem.
Upgrade procedure already in progress
Cause:
The unit received multiple upgrade requests at approximately the same time. However, only
one request can be handled at a time. The later request receives this error message.
Solution:
Issue one upgrade request at a time and wait for the unit to respond.
Invalid firmware file
Cause:
The unit performs a number of checks to determine the validity of the file. If it finds problems
with the file, such as the file not being a firmware file with .
sqrfw
extension, it displays this error
message.
Solution:
Use a firmware file with
.sqrfw
extension.
Device hardware is incompatible
Cause:
If the image identifier of the hardware does not match the image identifier of the firmware
file, this error message indicates that the selected firmware file is not intended for the unit. In that
case, the upgrade procedure is terminated. The fixed image and the upgrade image stay in the
memory of the unit. After a reboot, the unit runs the same image as before the reboot.
Solution:
Use a firmware file which is compatible with the unit.
Firmware file is corrupt
Cause:
The firmware file contains a CRC error. When this error occurs, the unit reboots
automatically and restarts with the fixed image.
Solution
: Download and install usable firmware.
Rule validation failed
Cause:
The firmware file is not suitable for this particular device.
Solution
: Upgrade with firmware intended for this unit.
Failed to write firmware to flash
Cause:
The firmware file is streamed directly into flash. Various errors may occur while writing the
firmware to flash. There may be connection loss, for example, or a reboot during the upgrade
procedure. If any such error occurs, the unit reboots automatically and restarts with the fixed
image.
