3.3 Power-up the LAN Module
The LAN module will automatically detect if it is connected to or disconnected from a
network. It will also automatically look for a network server and receive or create an IP
address. It will also broadcast its IP address and hostname to all other devices on the
network.
1. Insert the module into any slot of the HFE rack. The front panel LAN status LED will
initially be red.
2. The LAN cable may be connected before or after the module is inserted.
3. For a server network, wait about 10 seconds.
See that the front panel LAN Status LED turns green.
4. For a peer-to-peer network, wait about 60-90 seconds.
See that the front panel LAN Status LED turns green.
When the LAN Status LED turns green, the module has received an IP address.
Run the discovery tool to check the IP address received by the module.
If the LAN Status LED does not turn green, see troubleshooting section.
Note – There should be at least one HFE supply in the rack for the module to operate.
3.4 IP Address
The simplest and most reliable way to open a network connection is using the module’s IP
address. This is a group of four numbers separated by periods (for example: 10.1.15.123).
This IP address may be viewed by running the discovery tool.
There are three modes by which the module can get an IP address, as show in this table:
IP Address DHCP Auto-IP Static IP
Mode Select DHCP is default after
“LAN Reset”
Default after “LAN
Reset” if no DHCP
server is used
May be set in the “LAN Modify”
web page (see section 5.5.2)
or by SNMP.
Assignment Assigned by the

the IP defaults to DHCP or Auto-IP,
