NOTE: On some browsers, the Retry page may appear even though the software
upgrade was successful. If this occurs, before clicking on retry, refresh the web
page and check the version number. If the new version number appears at the
top of the page, the software upgrade was successful. If the old version appears,
click Retry.
If there is a power outage or glitch during the software download, the KUMO will
boot the older software version and the upgrade process can then be re-started
by the user. This happens because the KUMO has been designed with a safety
feature where an internal “safe” copy of the previous software is retained in the
event the updating process fails.
Safeboot Reset
If your KUMO firmware becomes corrupted to the point of freezing the device,
you can reset to a safeboot firmware image. The existing KUMO network
configuration (DHCP or Static IP) is retained during safeboot. When safeboot is
active you can then re-install the latest firmware via the web interface to regain
full system operation.
IMPORTANT: A KUMO device running safeboot firmware is not operational other than
being accessible on a network so compatible firmware can be installed.
To perform a KUMO safeboot:
1. Power down the KUMO device.
2. Engage the reset function:
• For a KUMO router, insert a straightened paper clip or similar device into the
reset slot on the rear.
• For a KUMO CP, press and hold both the
SHIFT SRC
and
SHIFT DEST
buttons on the panel.
3. Apply power to the device, wait at least 5 seconds and then release the
reset function.
