System Hardware Manual
4 - 103
6.4.2.2
GCD-CP10IP Address Assignment
The GSWU Main board will be provided with an IP address
from the back plane CPU during the initialization sequence.
The provision of an IP address from the back plane will
identify the Main board. If during initialization, the IP address
is set to
0
by the CPU, the blade is then determined to be an
Add-on
.
The IP address for the GSWU 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 GSWU 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 GSWU units in the system until it
receives an acknowledge message from the Main board.
The Main board receiving this broadcast message will
acknowledge by sending port identification information to
the Add-on board.
6.4.2.4
Port Number Determination
When a Main board 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 the
the Add-on boards be inserted sequentially starting with the
desired lower port numbers first.
When a board is removed, the port numbers are not
automatically removed. The operator, however, can remove
any assignment by accessing the Main board GUI.
Example:
Main board is inserted in slot 3, one Add-on board inserted
in slot 5. Main board has ports 1 ~ 8; Add-on board has
ports 9 ~ 16.
1. User inserts a new Add-on board in slot 2.
The new board gets assigned ports 17 ~ 24.
