See “10Base-FL hot standby fiber optic ethernet switch” on page 46 or “100Base-FX hot
standby fiber optic ethernet adapter” on page 47 for more information.
Network connections
The D400 supports a network interface through Ethernet connections to the 4-Port
Twisted-Pair Ethernet Switch or Redundant Twisted-Pair Et COM2 Port Adapter.
Within the operating system of the D400, the card in slot 11 is assigned to Ethernet
interface
eth0
and the card in slot 12 is assigned to Ethernet interface
eth1
.
All RJ-45 connectors have the same signal definition. However, the rear Ethernet ports are
auto MDI/MDIX and can support a straight-through or crossover cable.
See “4-Port twisted-pair ethernet switch” on page 45 and “Redundant twisted-pair
et COM2 port adapter” on page 49 for more information.
To connect the D400
to network devices
Plug network cables into the D400 Ethernet ports.
Figure 37: D400 Ethernet ports
NOTE
If the D400 is deployed in the presence of strong RF energy in the 110 MHz to 125 MHz
band, such as airport Instrument Landing System (ILS) localizers or aviation radio
transmitters, it is recommended that shielded twisted-pair Ethernet cables be used.
Front network port
To access the D400’s HMI, a local or portable PC can be directly connected to the network
port located on the front panel of the D400.
The front network port is tied to the network interface card in the NET1 slot (slot 11) (
eth0
for configuration purposes in a single Ethernet configuration or
eth1
for dual Ethernet
configuration).
To connect a local PC
to the D400
Connect the supplied straight-through Ethernet cable (GE Item No. 977-0209LF) to your
computer’s network communications port and to the D400's front Ethernet port. Older
computers without auto MDIX Ethernet capability may require an Ethernet cross-over
cable.
