Problem Solution
I can’t use the KA9220 or
KA9270 Console Modules
with the KM0832.
The KM0832 does not support these two Console
Modules. Instead, use the KA9222, KA9272, and
KA9233 Console Modules with the KM0832.
The console monitor does
not display and there is no
response to keyboard and
mouse input.
Verify that all cables are securely connected and in good
condition, including those of the Console Modules, CPU
Modules, and Category 5 cable.
Note: We strongly recommend that you use Category 5
shielded twisted pair (STP) cable.
Upgrade the firmware for the CPU Modules.
I can’t use the KA9222 and
KA9272 Console Modules
to login to the KM0832.
Verify that the username and password are correct.
Upgrade the firmware for the Console Modules.
I can’t use an Ethernet hub
to connect the Console and
CPU Modules to the
KM0832.
Although Category 5 cable is used to connect the
Console and CPU Modules to the KM0832, it does not
support the Ethernet protocol; thus, you cannot use an
Ethernet hub to connect them.
The password for the
Default Super Administrator
account needs to be reset.
See “Restoring Original Factory Default Settings” on
page 111.
I upgrading the firmware,
but some of the modules
were not upgraded
successfully.
See “Upgrade Failed” on page 66.
The firmware upgrade
process was prematurely
aborted and now some of
the modules are
inoperable.
