Troubleshooting
Overview
Operation problems can be due to a variety of causes. The first step in solving
them is to make sure that all cables are securely attached and seated completely
in their sockets.
In addition, updating the product’s firmware may solve problems that have
been discovered and resolved since the prior version was released. If your
product is not running the latest firmware version, we strongly recommend that
you upgrade. SeeUpgrading Firmware, page 73, for upgrade details.

Problem Solution
I can’t use the KA9222 or
KA9272 Console Modules
with the KM0832.
The KM0832 does not support these two console
modules. Instead, use the KA9222A, KA9272A, and
KA9233 Console Modules with the KM0832.
The KVM console monitor
does not display and there
is no response to keyboard
and mouse input.
1. Verify that all cables are securely connected and in
good condition, including those of the console mod-
ules, KVM adapter cables, and Cat 5 cable.
2. Upgrade the firmware for the KVM adapter cables.
I can’t use the KA9222A
and KA9272A Console
Modules to login to the
KM0832.
1. Verify that the username and password are correct. If
after verifying that the username and password are
correct you still cannot login, then follow Step 2.
2. Upgrade the firmware version of the console modules.
I can’t use an Ethernet hub
to connect the console
modules and KVM adapter
cables to the KM0832.
Although Cat 5 cable is used to connect the console
modules and KVM adapter cables 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.

I upgrading the firmware,
but some of the modules
were not upgraded
successfully.
See Upgrade Failed, page 79
The firmware upgrade
process was prematurely
aborted and now some of
the modules are
inoperable.
