9. TROUBLESHOOTING
LAN Status LED Stays Red
If LAN status LED stays red, then the module is not connecting to the network.
A. Verify the LAN cable is connected to an active network. Look at the front panel link LED
(part of the RJ-45 connector, see section 1.3) and verify it is green. If the LED is not lit,
then the LAN cable is not connected properly.
B. Wait longer and try to read the IP address again. In the Auto-IP mode the module will
wait a full 60-90 seconds to assign an IP address after powerup.
Cannot Communicate to the Module
If the LAN Status LED is green and the module has a valid IP address, and you still cannot open
a web page, VISA or socket connection then try “pinging” the module. The ping utility verifies
the computer can send a message and get a response from the module over the network.
Open a command line window by:
A. Click the “Start” button, Select “Run…”
B. A “Run” window opens. Type: cmd <Enter>. See the command window open
C. Type “ping <IP address>”
Verify the ping packets had successful responses
If the “ping” does not get responses from the module, then there is a mismatch between
the module and the computer LAN settings. Also, the ping function may be disabled in the
module. In this case, do a module “LAN Reset” and try to connect again
Cannot Open Web using Laptop or Dual-LAN Card Computer
If you have a computer with two network cards, the computer may not know which card to
use when trying to open the HFE web page. Verify the two cards do not have over-lapping
IP address ranges, otherwise it may be necessary to disable or disconnect the network card
that is not being used.
If you have a laptop computer with an Ethernet jack and a wireless network, it may be necessary
to disable the wireless LAN port.
Web Page “Refresh List” Does Not Find Slave Supplies
When you are using a LAN chain of supplies, the web page Refresh List button should detect
all the connected slave supplies. If it does not:
A. Verify all slave supplies are set for unique addresses.
LAN Status LED is blinking
While setting an IP Address, Duplicate IP has been detected. Stop the blinking by a LAN
specific command or by the Blink Identity command on the Web page and try assigning a
new IP Address.
