Troubleshooting for ENET Communication 
 
DeviceInstaller does not 
detect your device. 
Your ENET cable is not a 
cross cable.  
 
Power supply is not turned 
on.  
 
The network that your 
computer is on cannot reach 
the network that the unit with 
the ENET option is connected 
to.  
 
 
 
 
 
 
 
 
 
DeviceInstaller is not 
configured to use the 
Ethernet card on your 
computer that is connected to 
the network which has the 
unit with ENET option on it. 
Use the correct ENET cross 
cable.  
 
Turn the power supply ON.  
 
 
Connect a laptop to the HUB 
or to the switch that the unit 
with the ENET option is 
connected to, and ping the 
computer you are trying to 
use DeviceInstaller on. If no 
response is seen, then 
contact your network 
administrator and find out if 
ICMP requests are being 
filtered on the network and a 
possible reason for not being 
able to contact the computer.  
 
See “Selecting a Network 
Adapter” on page 6-10. 
Found device is not 
reachable. 
Your network is not 
configured properly. 
Contact your network 
administrator.

The power supply is not 
responding. 
The communication port on 
the power supply unit is not 
selected properly. The

unit is not valid. The address

communication port. Refer to 
the correct power supply 
address using the front panel.
