Upgrade Failed
If the upgrade failed to complete successfully a dialog box appears asking if
you want to retry. Click Yes to retry. If you Click No, the Upgrade Failed
screen appears. Click Cancel to close the firmware upgrade utility. See the next
section, Firmware Upgrade Recovery, for how to proceed.
Firmware Upgrade Recovery
There are basically two conditions that call for firmware upgrade recovery:
When you begin a firmware upgrade, but decide not to proceed with it.
When the mainboard firmware upgrade fails.
Note: If one of the cascaded switches fails to upgrade successfully, unplug it
from the installation and perform the recovery and upgrade operation
independently. After it has been successfully upgraded, plug it back into
the installation.
To perform a firmware upgrade recovery, do the following:
1. Power off the KL3116 / KL3116T.
2. Slide the Firmware Upgrade Switch (see page 8) to the Recover position.
3. Use the firmware upgrade cable (provided with this unit), to connect a
COM port on your computer with the firmware upgrade port of the switch.
4. Power on the KL3116 / KL3116T.
5. Follow the upgrade procedures that begin with the Starting the Upgrade
section (see page 58).
6. After the upgrade completes successfully, power off the KL3116 /
KL3116T.
7. Slide the Firmware Upgrade Switch back to the Normal position.
8. Power on the KL3116 / KL3116T.
