10Base-FL hot standby fiber optic ethernet switch
The Hot Standby Fiber Optic Ethernet Switch (GE Item No. 520-0214LF) is a 10BaseFL (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 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 Ethernet Module and cable
(GE item 580-3410 & 977-0544)
See “Fiber optic serial connections” on page 62 for typical cable connections.
Configuration options
There are no selectable options on the Hot Standby Fiber Optic Ethernet Switch card.
