3.9 Hot Standby Fiber Optic Ethernet Switch
The Hot Standby Fiber Optic Ethernet Switch (GE Part No. 520-0214) is a 100BaseSX (820-
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 Hot Standby Fiber Optic Ethernet Switch can be installed in the NET1 or NET2 slot
(slots 11 and 12) on the D400.
See section “4.5 Fiber Optic Connections” for typical cable connections.
