Troubleshooting
CXi-specific Issues
Table 25: CXi Troubleshooting
Symptoms Probable cause Corrective Action
Unable to
connect to the
controller
Database being used is
from a system that had
dual-VLANs enabled,
so the management PC,
untagged on VLAN 1,
cannot reach the
controller on the Voice
VLAN.
Run vlan_off command from the
RTC console (through the RS-232
serial port) to reset the controller
and disable the VLANs.
Run vlan_on to enable the
VLANs.
The commands will cause the
controller to reboot, so wait a
couple minutes before trying to
connect with your PC, attached to
CX port 17.
IP Phones on
third-party
Layer 2 switch
cannot connect
with the CXi
System has VLAN
enabled but the “tagging”
is being removed prior to
connecting with Port 17.
The CXi must receive VLAN tags
(if VLAN enabled) to allow an IP
phone to connect with the CXi.
The third-party L2 switch needs to
pass the Q and P tags to Port 17.
Unable to
connect to the
DSL modem
Bad connection,
incorrect password,
incorrect username, or
wrong protocol.
Review Maintenance Logs for:
Wan_port: state=down,
proto=pppoe, cause=wan=start.
Review ISP information sheet and
make sure that the username, pw
and protocol are correct.
Disable and Enable the WAN
Access in Internet Gateway/Wan
Settings.
CXi ports 1 - 16
not functioning.
Layer2 port IP Address is
not programmed.
Ensure IP Network Configuration
is properly programmed.
