Connecting the Antennas

You can attach the provided LTE antennas directly to the ES440. They operate
well when the antenna fans are placed in a V (or rabbit ear) position, with 90
degrees of separation. However, if the area where you want to place the ES440
(such as near an enterprise router) does not have optimal signal coverage or is
near RF noise interference, you can place the antennas remotely using brackets,
and connect them to the ES440 using a coaxial cable. An RF site survey may be
required to determine the best location. See
To connect the antennas:
1. Connect both LTE antennas, placing your fingers on the knurled nut, as
shown in the illustration.
2. Adjust the antennas so they are in a V-formation, with a separation of 90
degrees.

Connecting the Configuration PC

There are 3 local management ports on the ES440 for the configuring PC to
connect to: Ethernet, USB, and serial. You can configure the USB port as a virtual
Ethernet port or a virtual serial port.
For the initial startup and configuration, you can either:
• Connect the PC to the ES440 Ethernet port.
or
• Connect the PC to the USB port.
