CRS-170A L-Band 1:1 Redundancy Switch MN/CRS170A.IOM
Modem and Switch Configuration Revision 13
4–4
4.2.1 CDM-625/A Remote User M&C Ethernet Interface
4.2.1.1 For CDM-625/As Without the Optional IP Packet Processor
You may configure one of the CDM-625/A’s four available 10/100 Ethernet ports for M&C
Ethernet. As configured in Dedicated Management Port Mode, when the modem is offline the
M&C-designated port remains functional and available for operation, while the three remaining
ports are unavailable. Otherwise, if none of the 10/100 Ethernet ports are reserved for M&C
operation; all four ports become unavailable when the modem is offline.
See the CDM-625A or CDM625 Advanced Satellite Modem Installation and Operation
Manual (CEFD P/N MN-CDM625A or MN-CDM625) for instructions to configure one of
the four 10/100 Ethernet ports as the Dedicated Management Port for remote
Ethernet M&C.
TO AVOID ETHERNET NETWORKING LOOPS – If you configure more than one
Ethernet port for Ethernet traffic, you must use separate Layer 2 switches unless the
Layer 2 switch in use isolates these ports from one another.
4.2.1.2 For CDM-625/As Equipped With the Optional IP Packet Processor
You may not configure your modem for Dedicated Management Port Mode when the optional
IP Packet Processor is installed and enabled
. Under such functionality, in 1:1 redundancy Port 1
is available only for M&C on both modems, while Ports 2, 3, and 4 are disabled when a modem
is in the Offline state.
TO AVOID ETHERNET NETWORKING LOOPS – While in 1:1 Redundancy mode, with the
optional IP Packet Processors enabled and both units operating in Managed Switch
Mode, the Port 1 M&C Ethernet must be isolated from the Ethernet Traffic. Also, if you
use more than one of the Traffic Ports (Ports 2, 3, or 4), you must use separate Layer 2
switches unless the Layer 2 switch in use isolates these ports from one another.
