NSTALLATION

The configuration of the Webcache is preserved after a software upgrade 
has been performed; you do not have to re-configure the settings.

An SNMP Trap is sent to your network management station when any of 
the following events occur:

■

When the software upgrade server is not available and automatic 
software upgrade detection is enabled.

■

A new software upgrade is detected.

■

A software upgrade is successful.

If the software upgrade is completed successfully, the trap indicates 
that the upgrade has been successful and tells you what software 
version the Webcache is now running.

■

A software upgrade fails.

If the software upgrade is completed unsuccessfully, the trap indicates 
that the upgrade has been unsuccessful and tells you why it failed.

For more information about SNMP Traps, see “SNMP Traps” on page 85.

The Webcache software upgrade process is robust and guards against an 
upgrade failure. Should a software upgrade fail, the Webcache will 
automatically revert to using the software version that was installed 
before the upgrade was started. The upgrade process is resilient to power 
failure, network failure or system failure. Prior to offering an automatic 
software upgrade, the Webcache will download the new software 
version onto temporary storage on the Webcache, ensuring that the 
complete software image file is available before commencing the 
upgrade.

To configure the detection of software upgrades using the Web interface:

1 Click Device View on the Toolbar.

2 Select System > Control > Upgrade Settings in the Navigation Tree.
