Redundancy Config
•
Redundancy Traffic IP Address – Enter the IP Address and subnet mask in the form
XXX.XXX.XXX.XXX/YY.
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.
