Hot standby fiber optic connections
The Hot Standby Fiber Optic Ethernet Switches support single-IP redundancy for the D400.
They provide automated fail over between two Ethernet fiber optic network connections
(
RX1/TX1
and
RX2/TX2
) that share a single MAC address. The 10-BaseFL switch (GE Item
No. 520-0214LF) operates at 820-850 nm and the 100BaseFX switch (GE Item No. 520-
0215LF) operates at 1300 nm.
Hot Standby Fiber Optic Ethernet Switches can be installed in the NET1 or NET2 slot (slots
11 and 12) on the D400.
If two Hot Standby Ethernet switches are installed in the NET slots, the system may be used
in a dual-IP redundancy mode. That is, each switch can be configured with a different IP
address to provide a back up network connection if the primary channel fails.
You can use the following glass optical fiber (GOF) cabling with the D400 Hot Standby Fiber
Optic Ethernet Switches:
•
50/125 µm core/cladding multi-mode (gradient index) cable
•
62.5/125 µm core cladding multi-mode (gradient index) cable
•
100/140 µm core/cladding multi-mode (gradient index) cable
•
200 µm core Hard-Clad Silica (HCS) multi-mode (step index) cable
You can use the following fiber optic terminations for D400 cabling:
•
ST Connectors
When calculating cable length, consider the following optical power levels:
•
100BaseFX optical transmitter power is –15.0 ± 4 dBm
•
100BaseFX optical fiber receiver sensitivity is typically –34.0 dBm
•
10BaseFL optical transmitter power is –19.0 ± 2 dBm
•
10BaseFL optical fiber receiver sensitivity is typically –31.0 dBm
LED transmitters are classified as IEC 60825-1 Accessible Emission Limit (AEL) Class
1M. Class 1M devices are considered eye safe to the unaided eye. Do not view directly
with optical instruments.

standby fiber optic ethernet adapter” on page 50 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
.
