The Redundancy Traffic IP Address and subnet mask is different from the
Traffic/Management IP Address and subnet mask that is defined on the
Configuration | LAN | IP page (Sect. 7.5.4.3.2.1).
• 1: N Mode (use with CAUTION!)
– Use the drop-down list to set 1:N Redundancy mode as
Disabled or Enabled .
•
Packet Processor Redundancy – When you install and enable the optional IP Packet
Processor card in a 1:1 redundancy configuration (i.e., when you equip both the traffic and
backup modems with the optional IP Packet Processor and you connect them to a CRS-170A
L-Band or CRS-180 70/140 MHz 1:1 Redundancy Switch), there is no need to use the
drop-down list here, as the modem automatically enables the IP Packet Processor
Redundancy.
If it is desired to operate either modem outside of the redundant setup as a standalone unit, use
the drop-down list to select Packet Processor Redundancy for that specific modem as Disabled .

Force 1:1 switch (Only applies to Online modem)
When redundant modems are used and the selected unit is currently the
Online
unit, click
[Force 1:1 Switch] to force a switchover so the unit will then be in
Offline
(standby) mode. The
command is only valid for the Online unit in a 1:1 pair.
Redundancy Monitor
Monitoring of the redundancy setup – both the status of the active modem (i.e.,
Online
or
Offline ) and the detected presence of a redundancy switch – is provided in this read-only
section. Click
