Notice
• Do
not change the IP addresses of the IPCMPR/IPCEMPR and DSP cards once IP telephones
are registered to the PBX using these IP addresses.
The IP telephones will not operate properly if these IP addresses are changed.
• A DHCP server must be able to use a "client identifier" option specified by RFC 2131.
• The PBX will not start properly if the IP addresses cannot be assigned automatically by the
DHCP server when DHCP Client is set to Enable. In this case, you need to consult your
network administrator because the DHCP server on your network may not be running or a
network failure may have occurred. If the DHCP server cannot be available, change the DHCP
Client setting to Disable and set fixed IP addresses, then restart the PBX.
To change the DHCP Client setting, connect the PC with an RS-232C cross cable or Ethernet
straight cable. When connecting the PC with an Ethernet straight cable, make sure the PBX
is disconnected from the LAN and then connect the PC with an Ethernet straight cable using
192.168.0.101 for the IP address of the IPCMPR/IPCEMPR card.
