This section describes common problems you may encounter and possible solutions to them. The
Belgacom b-box can be easily monitored through panel indicators to identify problems.

POWER LED is Off
• Check connections between the Belgacom b-box, the external power
supply, and the wall outlet. • If the power indicator does not turn on
when the power cord is plugged in, you may have a problem with the
power outlet, power cord, or external power supply. However, if the unit
powers off after running for a while, check for loose power connections,
power losses, or surges at the power outlet. If you still cannot isolate
the problem, then the external power supply may be defective. In this
case, contact Technical Support for assistance.

Off
• Verify that the Belgacom b-box and attached device are powered on. • Be sure
the cable is plugged into both the Belgacom b-box and the corresponding
device. • Verify that the proper cable type is used and that its length does not
exceed the specified limits. • Be sure that the network interface on the attached
device is configured for the proper communication speed and duplex mode. •
Check the adapter on the attached device and cable connections for possible
defects. Replace any defective adapter or cable if necessary.
Network Connection Problems
Cannot ping
the
Belgacom b-
box from the
attached
LAN, or the
Belgacom b-
box cannot
ping any
device on the
attached LAN
• Verify that the IP addresses are properly configured. For most applications,
you should use the Belgacom b-box’s DHCP function to dynamically assign IP
addresses to hosts on the attached LAN. However, if you manually configure IP
addresses on the LAN, verify that the same network address (network
component of the IP address) and subnet mask are used for both the Belgacom
b-box and any attached LAN devices. • Be sure the device you want to ping (or
from which you are pinging) has been configured for TCP/IP.
