CD-CP00 IP Address Assignment

The CD-ETIA Main blade is provided with an IP address
from the back plane CPU during the initialization sequence.
The provision of an IP address from the back plane
identifies the Main board. If the IP address is set to 0 by the
CPU during initialization, the blade is determined to be an
Add-on.
The IP address for the CD-ETIA is assigned in Program
10-55 on the system. It contains the settings for the IP
Address, Subnet Mask and Gateway IP Address.
6.4.2.3

Group Formation

When a CD-ETIA determines that it is an Add-on board due
to the lack of an IP address from the backplane, it sends a
broadcast P2P message (defined in separate
documentation) to all the CD-ETIA blades in the system until
it receives an acknowledge message from the Main blade.
The Main blade receiving this broadcast message will
acknowledges by sending port identification information to
the Add-on board.
6.4.2.4

Port Number Determination

When a Main blade is initialized, the board assigns the first
eight ports as port 1 ~ 8. When subsequent Add-on boards'
broadcast messages are received, the Main board assigns
port numbers on a first-come, first-serve basis.
To have deterministic port assignment, it is recommended that

the Add-on boards be inserted sequentially starting with the
desired lower port numbers first.
When a blade is removed, the port numbers are not
automatically removed. The operator, however, can remove
any assignment by accessing the Main board GUI.
Example:
Main blade is inserted in slot 3, one Add-on blade inserted in
slot 5. Main blade has ports 1 ~ 8; Add-on blade has ports 9
~ 16.
1. User inserts a new Add-on blade in slot 2.
The new blade gets assigned ports 17 ~ 24.
