3.3.5 Ethernet M&C Connections – CRS-311 to User
The Ethernet Monitor and Control (M&C) Connection differs depending on which optional
Ethernet Interface Module and Ethernet Traffic Mode is used with the SLM‐5650/5650A:
• The single‐port 10/100/1000 BaseT (GbE) Interface Module, or
• The multi‐port Network Processor (NP) Interface Module.
3.3.5.1 Single-Port Ethernet Bridge Mode M&C Using the GbE Interface
Module
Referring to Figure 3‐12:
If the single‐port 10/100/1000 BaseT (GbE) Interface Module is installed for use in Single‐Port
Ethernet Bridge Mode (see Sect. 3.3.6.1) and the CRS‐311 is configured with the CRS‐306 or
CRS‐307 RMI, and CRS‐316 or CRS‐336 TMI, you must connect only to the “J5 Ethernet” port on
the Redundant and Traffic modems.
You can have a single‐point connection via use of user‐provided CAT5 cables and a user‐
provided Layer 2 Ethernet switch.
Referring to Figure 3‐13:
If the single‐port 10/100/1000 BaseT (GbE) Interface Module is installed for use in Single‐Port
Ethernet Bridge Mode (see Sect. 3.3.6.1) and the CRS‐311 is configured with the CRS‐505 RMI
and CRS‐515 TMI, you must connect only to the “J5 Ethernet” port on the Redundant and Traffic
modems. Be sure to use the same port number that was used for all corresponding interfaces
(User Data/RMI/TMI) – in the example shown, “Port 3” is used.
You can have a single‐point connection via use of user‐provided CAT5 cables and a user‐
provided Layer 2 Ethernet switch.
3.3.5.2 Multi-Port Ethernet Bridge Mode M&C Using the Network
Processor (NP) Interface Module
Referring to Figure 3‐14:
If the multi‐port Network Processor (NP) Interface Module is installed for use in Multi‐Port
Ethernet Bridge Mode (see Sect. 3.3.6.2), you must connect only to the “J5 Ethernet” port on
the Redundant and Traffic modems. You can have a single‐point connection via use of user‐
provided CAT5 cables and a user‐provided Layer 2 Ethernet switch.
Because “Port 1” on the TMI/RMI incorporates a Gigabit Ethernet switch, it is
important
not to use this port.
