9 MAINTENANCE

9.1 SOFTWARE UPGRADE

The application software in the SNMP/Web adapter may be upgraded (please note that the upgrade
procedure can be performed only by the supervisor and by rw users). The procedure to upgrade the
software is described below:
Transfer the new software (gedeappXXX.bin) to the device using ftp or sftp
Start the upgrade by injecting the upgrade command at the console or by pressing the upgrade
button in the Upgrade web page (System section)
Reboot the system to complete the upgrade procedure
NOTE: Make sure to use binary transfer to upload the file (binary transfer is selected with the binary
FTP command). Particularly, the FTP client on Windows defaults to ascii transfer – ascii transfer corrupts
the binary file during upload, and the upgrade procedure fails.
Although the procedure itself may seem trivial, there is a set of advices to be considered. First of all, the
upgrade procedure has been tested to be safe. However, any interruption to the procedure (even
accidental) may cause an abnormal termination. This means that any access to the adapter may be
lost if the upgrade procedure is not completed successfully – at that stage, the only recovery
mechanism is the adapter replacement. Therefore:
Never power off or un-plug the device during upgrade
Use only GE officially released software
Avoid unnecessary upgrades (in line of practice, only perform upgrades when recommended to
do so by GE)

9.2 CONFIGURATION FILE

The SNMP/Web adapter settings are stored in non-volatile memory. It is possible to store the settings in
a file, download it, or even upload a new configuration file.
To store the settings in a file, inject the nvdump command at the console. This will create a gedeups.cfg
file in the FTP area. The file can then be downloaded via ftp or sftp.
Also the web interface offers access to the SNMP/Web adapter configuration: Configuration page in the
System section. The configuration is shown in a text area and it can be selected and copied to any text-
based editor.
Finally, it is also possible to upload a new configuration file. This procedure can be performed only by
the supervisor or rw users. Mind that this is not the recommended procedure to change the adapter
settings, as the device will not perform any check on the downloaded file – operation of the SNMP/Web
adapter may be severely affected by a corrupted configuration file. In any case the procedure is
described below:
Transfer the new configuration file (gedeups.cfg) to the device using ftp or sftp
Update the configuration by injecting the nvupdate command at the console
Reboot the system to begin using the new configuration

9.3 LOGS

The SNMP/Web adapters maintain a log of the user activity (System log) and a log of UPS alarms (UPS
log). The logs can be accessed over the web interface (Log section) or over the console interface (syslog
and upslog commands). The logs can also be stored in a file and downloaded from the adapter. In order
to download the log files, inject the logdump command at the console. This will create ups.log and
sys.log in the FTP area. The files can then be downloaded via ftp or sftp.
