Connect WAN Interface Cable
Important pre-install step!
Some versions of eNB software require you to select the WAN
connection type in the eNB GUI b
efore
you connect an optical fiber or copper cable to the eNB
interface. In such cases, wait until you enter the basic configuration settings before you
connect the WAN cable.
To configure the connection type, use an Ethernet cable to connect a computer to the LAN
port on the eNB. Log in to the eNB GUI, per the instructions in section 3.5. Once you are logged
in, go to the Network > WAN/LAN menu. In the
Connect Type
field, select either fiber (default)
or copper (Figure 3-3).
Verify this setting before hanging the eNB on a tower or other structure, especially if you are
using copper. This will avoid a tower climb to bring the eNB down, should you forget to set the
Connect Type
to the correct setting.
