Invalid IP
configuration
The system has a default IP configuration
which might need to be changed to match
your local IP environment. Temporarily change
the IP configuration of your computer so that
the subnet configuration matches the system
configuration. Specify 255.255.255.0 as the
subnet and use IP address 192.168.1.191.
After you change your computer’s IP
configuration, connect to the system and
change its IP settings to match the IP
environment of your local network. Change
your computer’s IP configuration back to its
original settings, and then connect to NBX
NetSet using the new IP address. See
“Establishing IP Connectivity” in the NBX
Installation Guide.
Cannot open
NBX NetSet
using the
administrator
username and
password.
The CAPS LOCK

NBX NetSet username and passwords are
case-sensitive. For example, NBX NetSet
accepts “administrator” but it rejects
“Administrator” and “ADMINISTRATOR”.

Music-on-Hold (MOH) Input Device” in the
NBX Installation Guide.

set too low.
See “Adjusting Music-on-Hold (MOH)
Volume” in the NBX Installation Guide.
Lose date and
time when
rebooting the
system.

.
NBX NetSet is
very slow in
responding.
Your network
uses a proxy
server for Internet
access.
A common networking practice is to employ a
proxy server to shield your network from
intrusion by unauthorized users. However,
communications with NBX NetSet do not need
to pass through the proxy server. To speed
access to NBX NetSet, configure your browser
to access the NBX system without going
through the proxy server.
