ETAS Troubleshooting Problems
ES592.1 - User Guide 37
Cause: ETAS Hardware hangs
Occasionally the ETAS hardware might hang. In this case switch the hardware
off, then switch it on again to re-initialize it.
Cause: Network Adapter temporarily has no IP Address
Whenever you switch from a DHCP company LAN to the ETAS hardware net-
work, it takes at least 60 seconds until ETAS hardware can be found. This is
caused by the operating system’s switching from the DHCP protocol to APIPA,
which is being used by the ETAS hardware.
Cause: ETAS Hardware had been connected to another Logical
Network
If you use more than one PC or notebook for accessing the same ETAS hard-
ware, the network adapters used must be configured to use the same logical
network. If this is not possible, it is necessary to switch the ETAS hardware off
and on again between different sessions (repowering).
Cause: Device driver for network card not in operation
It is possible that the device driver of a network card is not running. In this case
you will have to deactivate and then reactivate the network card.
To deactivate and reactivate the network card:
1. To deactivate the network card first select in the Windows
start menu the following item:
i. Windows XP:
Control Panel  Network Connections

Sharing Center
 Manage Network Connections
2. Right click on the used network adapter and select Disable in
the context menu.
3. In order to reactivate the network adapter right click on it again
and select Enable.
Cause: Laptop power management deactivates the network card
The power management of a laptop computer can deactivate the network card.
Therefore you should turn off power monitoring on the laptop.
To switch off power monitoring on the laptop:
1. From the Windows Start Menu, select
i. Windows XP:
Control Panel  System.
Then select the Hardware tab and click on Device
Manager.
