Troubleshooting
General Operation
Problem Resolution
Erratic operation The CN8000 needs to be started before the KVM switch
1. If the CN8000 is connected to a KVM switch, make sure
to power it on before powering on the switch.
2. If the KVM switch was started before the CN8000, reset
or restart the KVM switch.
The CN8000 needs to be reset (see Firmware Upgrade/
Reset Switch, page 8, point 1).
I can’t access the
CN8000, even though I
have specified the IP
address and port number
correctly.
If the CN8000 is behind a router, the router’s Port
Forwarding (also referred to as Virtual Server) feature must
be configured. See Port Forwarding, page 113, for details.
Mouse pointer confusion If you find the display of two mouse pointers (local and
remote) to be confusing or annoying, you can use the
Toggle Pointer Display function to shrink the non-
functioning pointer. See page 44 for details.
Mouse movement
extremely slow
There is too much data being transferred for your
connection to keep up with. Lower the video quality (see
Video Settings, page 46) so that less video data is
transmitted.
Changing Mouse Sync
Mode to Manual makes
the CN8000 crash.
The CN8000 hasn’t crashed. You can wait approximately 5
minutes for normal operations to resume, or you can reset
the CN8000 to get it going right away (see Firmware
Upgrade/Reset Switch, page 8, point 1).
I can’t access my
PN9108 when I click the
Power Management
icon.
Since the PN9108 already has over IP functionality, there is
no need for the CN8000 to provide it. Therefore, only PON
devices that don’t have their own over IP functionality (such
as the PN0108) are supported.
The Windows Client link
doesn’t appear in the
Remote Console Display
when I log in with Firefox.
The Windows Client link requires ActiveX. Since Firefox
doesn’t support ActiveX only the Java Applet is available.
