Network Connections
Dual Ethernet Port and Dual SFP Port
The back side of the EMG unit is equipped with two Ethernet and two SFP ports. The EMG
network interfaces are 10/100/1000 Base-T Ethernet for use with a conventional Ethernet network as
. Use standard RJ45-terminated cables, such as a Category 5 or 6 patch cable.
CAT5E or better cables are recommended for 1000 Base Ethernet. Network parameters must be
configured before the EMG can be accessed over the network.
The SFP interfaces support the use of single and multi-mode SFP transceivers. Fiber optic 1 Gigabit
SFP transceiver modules may be used. See
.
Note:
EMG will recognize two network connections. Either Eth1 or SFP1 is active, but
not both. Either Eth2 or SFP2 is active, but not both.
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. The EMG can also be equipped with a factory-installed
network interface card (NIC) (Ethernet RJ45 or SFP ports). The NIC with SFP ports can support
single/multi-mode fiber optic SFP transceiver modules at 1 Gigabit speed.
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
