Software upgrade
The management agent supports application software upgrade using either the web-
based interface or the SNMP interface.
PTP 600 software images are digitally signed, and the ODU will accept only images
that contain a valid Motorola PTP digital signature. The ODU always requires a reboot
to complete a software upgrade.
NOTE
Obtain the application software and this user guide from the support website
BEFORE warranty expires.
NOTE
ODU software version must be the same at both ends of the link. Limited
operation may sometimes be possible with dissimilar software version, but
such operation is not supported by Motorola.
The management process for software upgrade is described in detail in Upgrading the
PTP 600 on
page 6-77.
Softw
are can be downgraded using Recovery mode as described in Recovery mode on
page 1-50.
Recovery mode
The PTP 600 recovery mode provides a means to recover from serious configuration
errors including lost or forgotten passwords and unknown IP addresses.
Recovery mode also allows new main application software to be loaded even when the
integrity of the existing main application software image has been compromised. The
most likely cause of an integrity problem with the installed main application software
is where the power supply has been interrupted during an earlier software upgrade.
The ODU operates in recovery mode in the following circumstances:
• When a checksum error occurs for the main application software image.
• When the PIDU recovery button is pressed at the same time as the ODU is
rebooted or power cycled.
