What to do
Connect the Console to the SC board.
Run the configuration utility to set the
IP settings.
Try to "ping" the board/module from the
SC board. If ping fails, check for
network problems/definitions and try to
reset the board/module
Check cables (uplink).
Check if default gateway can reach the
IP of the board/module.
Check if the board/module got the
correct IP.
Check that the IP addresses of the
boards are not used by another entity.
Check the validity of the IP address,
subnet and default gateway.
If default gateway is not used, enter
0.0.0.0
Check that only your BootP server
contains TP-1610 MAC address.
Check that there is no other BooP
server active in the subnet. If there is,
check that the MAC addresses for the
boards are not defined in the second
BootP server to prevent the boards
from receiving IP addresses from the
wrong source.
Connect the uplink.
Reset the board.
Ping to the configured IP addresses
while it is locked.
If the ping returns a response, then
another device is already using the IP
address.
LOCK the board and configure new IP
addresses for it. Then UNLOCK the
board.
