7-30 Troubleshooting

When incorporating the module again it has been disconnected, the network is not duplexed:

†Has the module been completely disconnected?

οWhen you disconnected the module using NEC ESMPRO and tried to incorporate it again, the network may not be duplexed if the module is not completely disconnected. Make sure that the module is completely disconnected by confirming that the FT-LED is turned off and the module is powered off, and then incorporate the module.

οIf incorporating the module does not start for a few minutes, try to incorporate it again.

When turning on the DC power after the module has been implemented, “$ESMALERT:HAS:C00706A6$ The driver failed to bind the Module.” is notified:

†After the module is implemented, if the timing to turn on the DC power is too early, this message may be displayed.

οRight after implementing the module, hardware is initialized. When the DC power is turned on before the initialization process completes, this message may be displayed, but there is not any problem. After that, if the DC power of the module is not automatically turned on, press the DC button again to turn on the DC power.

The network is not duplexed:

οIf the network is not duplexed, redundancy of the system is incomplete, and the status LED indicator does not illuminate green. Follow the steps below to check the network configuration:

[Procedure]

1.Run “ifconfig -a grep eth.”

If no message appears, the network is successfully duplexed.

If the standard device names for Linux (such as eth0, eth1) are assigned to Ether devices, the network is not duplexed.

------------------------------------------------------------------------------------------------

# ifconfig -a grep eth

 

eth0

Link encap:Ethernet

HWaddr 00:XX:XX:XX:XX:XX

eth1

Link encap:Ethernet

HWaddr 00:YY:YY:YY:YY:YY

------------------------------------------------------------------------------------------------

2.Run “udevstart.”

All the Linux standard device names will be renamed to the ones for your NEC Express5800/ft series (such as e08030, e13030), and the network is duplexed.

3.Run “ifconfig -a grep eth” again to confirm that no message appears.
