Description Solution
16#E289
The network module IP of the control
mode CPU on the main backplane slot 9
cannot be detected.
1. Make sure the network cables of the network
modules on the main backplane slot 9 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 9
is connected to the network port 1, the network
module’s network cable of the standby mode
CPU on the main backplane slot 9 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 9 are on the same physical
network.
16#E28A
The network module IP of the control
mode CPU on the main backplane slot 10
cannot be detected.
1. Make sure the network cables of the network
modules on the main backplane slot 10 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
10 is connected to the network port 1, the
network module’s network cable of the standby
mode CPU on the main backplane slot 10 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 10 are on the same physical
network.
16#E28B
The network module IP of the control
mode CPU on the main backplane slot 11
cannot be detected.
1. Make sure the network cables of the network
modules on the main backplane slot 11 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
11 is connected to the network port 1, the
network module’s network cable of the standby
mode CPU on the main backplane slot 11 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 11 are on the same physical
network.
