Symptom
The KVM
is
inaccessib
le.
The KVM
displays
an error
message.
Issue 20 (2020-09-25)
Handling Procedure
1. Use a third-party tool, such as
PuTTY, to run the telnet
address :2198 command to
check whether the KVM port is
normal. The default port
number is 2198. Log in to the
iMana 200 or iBMC WebUI,
choose Configuration >
Services, and check the KVM
parameter to obtain the actual
port number. If Telnet access is
unavailable, use a PC to directly
connect to iMana 200 or iBMC
for troubleshooting.
2. Clear all browser and Java
cache and close all browsers.
Then re-log in to iMana 200 or
iBMC.
3. Adjust the Java security level to
medium or lower, or add the
KVM address to the Java
exception sites.
4. Check the OS and browser
versions on the client. Firefox
23.0 is recommended. For
details about the operating
environment requirements, see
the iMana 200 or iBMC help
document.
● If the number of login users
exceeds the maximum value,
use the iBMC WebUI or CLI to
check whether other users are
using the KVM. If other users
are using the KVM, restart
iMana 200 or iBMC to force the
users to log out.
● If the KVM displays a message
indicating an unauthorized
user, clear all browsers and the
Java cache, and close all the
browsers. Then re-log in to the
iMana 200/iBMC.
● If the input signal is out of
range, check whether the OS
resolution exceeds the
maximum value 1280 x 1024.
