2: Introduction
EMG™ Edge Management Gateway User Guide 33
The EMG unit will recognize two network connections. One connection must be either Eth1 or
SFP1. The second connection must be either Eth2 or SFP2.
If a single mode and a multi-mode SFP module are both installed on the EMG unit, the device can
be configured to utilize one mode at a time.
One possible use for the two Ethernet ports is to have one port on a private, secure network and
the other on a public, unsecured network.
Ethernet and SFP LEDs
The Ethernet ports and the SFP ports contain LEDs. The LED indicators are the following:

Green LED - indicates link status

Yellow LED - indicates activity status
