Default DHCP/IP address settings
When a defaulted or new B5800 Branch Gateway control unit is switched on, it requests IP
address information from a DHCP server on the network. This operation will occur whether the
LAN cable is plugged in or not. The process below is done separately for both the LAN port
(LAN1 in the configuration) and the WAN port (LAN2 in the configuration) on the back of the
control unit.
• The B5800 Branch Gateway makes a DHCP request for what IP address information it
should use.
• If a DHCP server responds within approximately 10 seconds, the control unit defaults to
being a DHCP client and uses the IP address information supplied by the DHCP server.
Note:
For this installation, we have not yet connected the control unit to the network so a
DHCP server will not respond.
• If a DHCP server does not respond, the control unit defaults to being the DHCP server
for the LAN using the following settings:
- For its LAN1 it allocates the IP address 192.168.42.1 and IP Mask 255.255.255.0.
It supports 200 DHCP clients using the addresses range 192.168.42.2 and
192.168.42.201, the IP Mask 255.255.255.0 and default gateway address
192.168.42.1 (the control unit LAN1 address).
- For its LAN2 if supported, it allocates the IP address 192.168.43.1 and IP Mask
255.255.255.0.
- Note that the B5800 Branch Gateway does not check that these addresses are valid
and or available on the network.
Important:
Once the control unit has obtained IP address and DHCP mode settings, it retains those
settings even if rebooted without a configuration file present on the System SD card. To fully
remove the existing IP address and DHCP mode setting the B5800 Branch Gateway must
be defaulted using Manager.
Connecting the control unit to the network
Before you begin
The system default settings must be changed to match the customer requirements before the
control unit is connected to the network. Use the Initial Installation Utility to assist in configuring
the system settings. To run the Initial Installation Utility, see
Using the Initial Installation
Utility on page 121.
The Initial Installation Utility is run using IP Office Manager from a PC or laptop that is
connected directly to the B5800 Branch Gateway LAN 1 port. The Initial Installation Utility will
