4.5.3.8 Ethernet Data Connections

	1. When using the CDM-625 in Dedicated Management Ethernet Port mode, all
	four of the offline modem’s Ethernet ports will be disabled unless the user
IMPORTANT	configures one of the four ports as the ‘Dedicated Management Port.’ For
	more information, refer to Sect. 5.4.13.3 CONFIG: IP Æ Setup in the CDM-625
	Advanced Satellite Modem Installation and Operation Manual.

2.When Ethernet (with no Sub-Mux) is the dedicated data interface employed in the redundancy system, the user should make all cabling connections using the wired-thru connection method explained in Sect. 4.5.3.8.1.

3.When Ethernet is utilized in combination with other data interfaces in the redundancy system – i.e., an IP Sub-Mux configuration – the user should make all cabling connections using the wired-around connection method explained in Sect 4.5.3.8.2.

4.5.3.8.1Ethernet Data Connection – Wired-thru Method (No Sub-Mux)

This redundancy approach is the recommended and preferred IMPORTANT connection method.

The wired-thruEthernet connection on the CRS-300 is the easiest and simplest choice for Ethernet redundancy. This connection method – the same as used on the standard serial data interface – provides a single connection (i.e., using one of four available RJ-45 ports) for the User Data Interface and provides simple Form-C relays that route the Ethernet connection from the User connection to either the Traffic or Redundant Modem.

If the Wired-thru method of Ethernet is the driving traffic data type Note 1 (refer to Figure 4-10through Figure 4-12):

•First, connect the Control/Data Cable CA/WR0066 (for control/data purposes) between the Redundant CDM-625 and the RMI (see Sect. 4.5.3.1).

•Next, connect and secure the Ethernet Data Cable CA-0000121 (HD-50M to RJ-45M, 6’) between the Redundant CDM-625 and the RMI:

oRJ-45F “10/100 Ethernet” connector labeled "1" (Port1) on the Redundant CDM-625, to

oHD-50M connector labeled “J1” on the RMI.

•Then, connect and secure the Control Cable CA-0000069 (HD-15M to DB-9M, 6’) between the CRS-316 or CRS-336 TMI(s) and the Traffic CDM-625(s).

•Finally, connect and secure the Cat5 Data Cable PP/CAT5FF7FTGY (RJ-45M to RJ-45M, 7’) between the TMI(s) and Traffic CDM-625(s):

oRJ-45F connector labeled "J5" on the TMI(s)Notes 2,3, to

oRJ-45F "10/100 Ethernet" connector labeled "1" (Port 1) on the Traffic CDM-625(s).
