Resetting an Ethernet SeaI/O Module
An Ethernet SeaI/O module may become no longer visible in the module list in the
Ethernet Config utility if the Ethernet SeaI/O module has been configured to use a
different subnet than the host computer.
In other cases, the Ethernet SeaI/O module doesn’t appear in the module list due to a
DHCP discovery failure. In either case, clicking on the “Recover Module” button
(see image on previous page) in the Ethernet Config utility will bring up the
“Module Reset” window shown below.
Before recovery begins, make certain that the PC and Ethernet SeaI/O module are on
the same network segment – they should be connected with an Ethernet crossover
cable, through a hub, or through a non-routing switch. Ethernet SeaI/O modules are
shipped with both an Ethernet patch cable (blue) and an Ethernet crossover cable
(yellow).
Enter the MAC address found on the label on the bottom of the SeaI/O enclosure. A
MAC address is made up of six pairs of hex digits separated by dashes (i.e., xx-xx-
xx-xx-xx-xx). While entering the MAC address, the indicator to the right of the field
will turn red if the MAC address entered is invalid. Once a MAC address is
successfully entered, the indicator light will turn green and the “Network Settings”
options will be enabled.
Contact your network administrator if you are unsure of the proper network settings
to choose. If a DHCP server is available, select the “Enable DHCP Configuration”
checkbox. Otherwise, complete the network settings and click the “Recover Module”
button to complete the configuration changes.
Proceed with configuring expansion modules, explained in the previous section, or
refer to the Troubleshooting section at the end of the manual for more information.
