Upgrading System Software
To perform an upgrade with the 3300 Software Installer Tool:
Time: This process takes approximately 45 minutes.
Time: This process will take approximately 1 to 2 hours including the backup,
restore, and reboot.
CAUTION: If you have a Universal NSU with a PRI database,
you may need to convert that database before you begin the
upgrade. Refer to page 76 and the RN for conditions.
Tip: To minimize the size of the database, you may want to ask your users
to delete any unneeded voice mail messages.
CAUTION: You may not downgrade the LX controller to a
software version prior to release 5.0. A downgrade would
render the controller inoperable.
CAUTION: You may not downgrade the MXe controller to a
software version prior to release 7.0. A downgrade could
render the controller inoperable.
PC or Layer2 switch connection must be to Ethernet port 1.
Note: The upgrade requires a change to a different set of DHCP options
(43/60 or 124/125) used to configure Mitel IP endpoints. The change is due
to reclassification of DHCP options by the Internet Engineering Task Force
(see RFC 2133 and RFC 3925). The old options can still be used to provide
backward compatibility with IP sets that have yet to be upgraded with firmware
that supports the new options. After the upgrade, the old options may be
removed to prevent future conflicts with standard use or other vendors’ use
of these options. The change to the new options is automatic for the internal
DHCP server.
