Problem
Solution
FTP - Server Unreachable
If FTP server specified in the upgrade panel is unreachable or
incorrect, the upgrade process halts until a response is received
from the FTP server or until a timeout occurs.
Wait and allow the FTP Server Unreachable message to appear.
FTP - File Not Found
The unit requires a package of upgrade files to be in the directory
specified by the upgrade path. This package must have all included
files and an upgrade.cnf file. Should this file not exist, or if the
contents of the file are not in the indicated places, the File Not
Found message will appear.
Verify that the upgrade package is in the correct directory and
confirm the upgrade path and IP address of the FTP server.
If the upgrade still fails, reinstall the upgrade package and begin
again.
Insufficient Partition Size
The latest 3.1.0.5.7 firmware is specifically applicable to Dominion
SX models - DSX16 and DSX32 only (purchased before August
2004). This version also supports the use with CC-SG 3.1
(CommandCenter SecureGateway) or higher.
Note that the attempt to upgrade firmware to the latest 3.1.0.5.7
version will be aborted if the SX unit is detected with less than 32mb
partition size. Then the upgrade will not be performed, and the unit's
operation will not be impacted. The unit will auto restart after the
upgrade is attempted. Following screen shots exhibit a sample
upgrade attempted for such unit (IP Address for the unit is
10.0.13.182).
