Note
:
IP sets require a
firmware upgrade to
support the new DHCP
options introduced
in 3300 Release 7.0;
otherwise, the sets
will fail to boot. Such
failures can occur, for
example, in a resilient
cluster of mixed software
releases or when sets
with old firmware are
added to a controller
after it was upgraded to
Release 7.0. For the sets
to boot, DHCP options
128-135 must be present
in the DHCP server.
After the sets have
booted, options 128-135
may be removed to
avoid future conflicts
with standardized or
other vendors use of
these options. If the
IP telephone displays
“TFTP LOAD FAILURE”
verify that the TFTP
Firmware, DSP and
Main software loads
are available and not
corrupted.
