Description Solution
1. Make sure the network cables of the network
modules on the main backplane slot 0 are
well-connected both on the control mode CPU
and standby mode CPU.
2. If the network module's network cable of the
control mode CPU on the main backplane slot 0
is connected to the network port 1, the network
module's network cable of the standby mode
CPU on the main backplane slot 0 must be
connected to the network port 1 as well.
3. Mare sure the network modules of the control
mode CPU and the standby mode CPU on the
main backplane slot 0 are on the same physical
network.

is connected to the network port 1, the network
module's network cable of the standby mode
CPU on the main backplane slot 1 must be
connected to the network port 1 as well.
