Upgrade System Software
The following conditions apply to both online and offline upgrades:
You will not be able to use the System Administration Tool until the
upgrade is complete or until you cancel the upgrade using the
Software Installer.
You will not be able to perform backups until the upgrade is complete
and the activation has been done.
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.
LLDP-MED non-compliant telephones cannot use LLDP for VLAN
discovery. They must use DHCP VLAN discovery. Non-compliant sets
are: 5001, 5005, 5010, 5020 IP Phones, 5140 IP Appliance, 5201,
5205, 5207, 5215 (single mode), 5220 (single mode), 5230 IP Phones,
5240 IP Appliance, 5485 IP Pager, and 5550 IP Console keypad.
Online Upgrade
Online Upgrade is the default upgrade method for Rel 8.0 and later.
Performing an Online Upgrade means scheduling very little down time for
your upgrade. You can perform most of your upgrade with the system
running. The only downtime will be during the reboot.
In addition, you can do the entire install, and then schedule the reboot
whenever it is convenient. You can close the Software Installer anytime
after the Installer has finished transferring the new files to the 3300. See
Table 8 for more information about closing the Software Installer before
the upgrade is complete.
1. Launch the Software Installer.
2. Choose 3300 ICP or MXe Server and click Next.
Note: You can use online upgrade only when upgrading from Rel 8.0 to a
later release. In this case, you can also use the internal FTP server.
