7.5 Manual - BS421 Configuration
TetraFlex® 7.5 Manual 2-61
However, if the BS421 is connected to another BSC, the IP address configuration must be
reset.
2.6.1.1.2 How does DHCP work with the SB421 (BSC)?
The IP address may be assigned by means of DHCP.
This means that the SB421 must first be started. When the SB421 is started her after the
BS421/1 must be started and then in a dual carrier system the BS421/2.
The BS421 gets an IP address from the PC’s DHCP server. This IP address is tied to the
BS421 MAC address.
If the MAC address is unknown to the PC, the BS421 will be assigned an IP in the range
172.16.1.200 - 249.
In this case the BS421 IP address must be changed.
2.6.1.1.3 Changing the BS421 IP
o Open C:\Program Files\DHCPServer\dhcpsrv.ini with notepad or another text editor.
o (Hint: save a backup of the original file before editing)
NOTE: All entries above the dotted line are factory presets and must only be changed for
redundant SB421 (change IP Bind to 172.16.1.19) or when IP address segments must be
changed.
