The Hot Standby Fiber Optic Ethernet Switch (GE Item No. 520-0214LF) is a 10BaseFL/
100BaseSX (820 to 850 nm) network switch that supports single-IP redundancy for the
D400. It provides automated fail over between two Ethernet fiber optic network
connections (RX1/TX1 and RX2/TX2) that share a single MAC address.
When the primary port (Fiber Optic Channel 1) receives no signal, or detects a fault signal
from the remote link partner, the D400 switches to the secondary port (Fiber Optic Channel
2) if it has a valid link. The D400 reverts to the primary port if the primary link is restored or
no signal is present on the secondary port. The data rate on each port is independently
detected and set to 10 Mbps or 100 Mbps.
The Hot Standby Fiber Optic Ethernet Switch can be installed in the NET1 or NET2 slot (slots
11 and 12) on the D400. Use of this card in slot 12 requires installation of the dual
redundant Ethernet CPU option which includes the PC/104-Plus 10/100BasetT Ethernet
Module and cable (GE item 580-3410 and 977-0544)
See "Fiber optic serial connections" on page 57 for typical cable connections.
There are no selectable options on the Hot Standby Fiber Optic Ethernet Switch card.
