Overview
Redundancy is an important issue for industry, and several different
solutions have been developed to prevent damage caused by
equipment or software failures. “Watchdog” hardware is required to
utilize redundant hardware, and a “Token” switching mechanism is
required for software. The CN2600 terminal server uses its built-in
dual-LAN ports to implement a “redundant COM” mode that keeps
your applications running smoothly.
Dual-LAN Redundancy
The CN2600 has two separate LAN ports that can be connected to
separate LAN networks. Dual-LAN redundancy involves setting up two
separate physical networks to connect the PC host with the CN2600.
In this case, the PC host must also be installed with two LAN cards. If
one of the networks fails, the PC host will still be able to communicate
with your serial devices over the redundant LAN.

Redundant COM
The “Redundant COM” (patent pending) operation mode can be used
to set up a redundant LAN between the CN2600’s COM ports and the
host computer. The redundant structure involves using the CN2600’s
two LAN ports to set up two independent LANs that connect the
CN2600 to the host computer. If either of the two LANs fails, the other
LAN will continue transmitting packets between the serial devices and
the host, with the data transmitted through the CN2600. One of the
biggest advantages of using Moxa’s Redundant COM mode is that the
“switching time” is zero. What this means is that if one of the LANs
fails, data transmission between the PC host the serial devices will not
be interrupted.

Dual-host Redundancy
The CN2600’s dual LAN cards can also be used to set up “dual-host”
redundancy. In this case, both networks (LAN A and LAN B in the
figure) are connected to two different hosts. If either of the two hosts
shuts down unexpectedly, the other host will continue transmitting
packets to (and receiving packets from) the serial devices connected
to the CN2600.

Dual-power redundancy uses two power inputs and redundant internal
power supplies to ensure that all of the CN2600’s functions will be
available, even in the event of power circuit failures.
