K.6 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-625A in a redundancy configuration.
