7.4 Management Tools
7.4.1 Software Update
The W2x terminals run Linux OS on an Intel hardware platform. The flash
file system is formatted as two partitions, each capable of holding a
complete software image. If a software update process should get
interrupted, e.g. power failure during the update process, there is always a
last known good firmware image to boot from.
7.4.1.1 Manual Software Update
Manual software updates is supported from FTP or HTTP(S) servers. It is
also possible to upgrade the software via a browser button in the WUI from
a local computer.
7.4.1.2 Automatic Software Update
Automatic software updates from Ericsson’s update server are supported.
In this case, the W2x terminals will at regular intervals poll the update
server for updates. If there is an image available a download and upgrade
process is initiated.
7.4.1.3 Backup and Restore Configuration
By using the WUI, the end-user can backup and restore configuration files
to/from a local PC.
7.4.2 System Log
The W2x terminals include a system log accessible both from the CLI and
WUI as a text file.
The system logging information is written to 5 files which are rotated in a
circular fashion. The files are limited to 200Kbytes each, which equals a
maximum of 1 MB total logging information. The files are not saved to flash
and will be lost when rebooting or when power is disconnected.
When persistent logging is enabled, the log files are written to flash
memory in two files alternately.
Different levels of logging (Emergency, Alert, Critical, Error, Warning,
Notice, Info and Debug) can be set depending on how much information is
desired.
The syslog events can be saved to a local file or forwarded to remote
syslog server.
7.4.2.1 BSD Syslog Remote Logging
The W2x terminals are able to distribute none, some or all system log
events using the BSD Syslog message format on UDP.
7.4.3 Fault Management
If an error condition occurs, the “Alarm” LED on the unit is lit (red) and the
corresponding cause is displayed in the WUI (on the Overview page). An
event message with severity level “Error” is also generated in the syslog.
