Ethernet Redundancy

Once you have determined the best configuration for near-to-far end Ethernet networks, you may
add the appropriate redundancy switches to one or both ends of the link(s):
•
1:1 Redundancy is supported using either a CRS-170A L-Band 1:1 Redundancy Switch or
a CRS-180 70/140 MHz 1:1 Redundancy Switch, and a user-provided, off-the-shelf Ethernet
switch.
•
1:N Redundancy is supported using a CRS-300 1:10 Redundancy Switch or a CRS-500
M:N Redundancy System in 1:N mode (in a wired-thru or wired-around configuration), and
is supported in Single-Port Ethernet Bridge (Managed Switch) and Router Modes (the
optional IP Packet Processor is required for Router Mode).
•
Packet Processor Redundancy is supported in both 1:1 and 1:N redundant configurations
using the CRS-500 M:N Redundancy System.
Refer to the pertinent switch Installation and Operation Manuals for detailed information on using
the CDM-425 Advanced Satellite Modem in a redundancy configuration.
