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
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.
4.5.3.8.1 Ethernet Data Connection – Wired-thru Method (No Sub-Mux)
IM PORTAN T
This redundancy approach is the
recommended and preferred
connection method.
The wired-thru Ethernet 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 4-10
through 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:
o RJ-45F “10/100 Ethernet” connector labeled "1" (Port1) on the Redundant
CDM-625, to
o HD-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):
o RJ-45F connector labeled "J5" on the TMI(s) Notes 2,3
, to
o RJ-45F "10/100 Ethernet" connector labeled "1" (Port 1) on the Traffic
CDM-625(s).
