CDM-750 10/100 Ethernet System Communication
Cable Connections
1. The CDM-750 “J4 | MGMT” port is reserved for use as the M&C interface in
CRS-500 operations.
2. Do not connect directly to any modem for User Remote M&C connections. All
User Remote M&C connections should use the CSU rear panel CRS-530
System Controller Serial “Remote Control” or Ethernet “10/100 M&C” ports.
For 1:N connections between the CRS-500 CSU and CDM-750 Modems: 10/100 Ethernet is used
by the CRS-500 to communicate to all modems. It is also used for “pass-through”
communications from the user and to/from the modems (including 10/100 Ethernet and Serial
M&C).
4.3.2.3.1 Ethernet System Communication Cable Connections –
10/100/1000 Gigabit Ethernet (GbE) Traffic Data
1. Make sure that the CDM-750 CONFIG: REMOTE CONTROL > Inband
(Inband Modem Control) is disabled.
2. The Redundant Modem RJ-45 port labeled “J4 | MGMT” is always
connected to the installed CRS-505 RMI Ethernet port labeled “Port 1.” Do
not use the “J4 | MGMT” port for any GbE traffic data connections.
3. Modem RJ-45 ports labeled “J5 | DATA” and “J6 | DATA” are intended for
use as the GbE traffic data connections.
Referring to Figure 4-8:
• First, for the Redundant Modem, connect the PP/CAT5FF7FTGY cable between the
Redundant Modem and the CRS-505 RMI as follows:
o
Redundant Modem RJ-45 ports labeled “J5 |DATA” or “J6 | DATA” to
o
CRS-505 RMI RJ-45 Ethernet connectors labeled “Port 2” through “Port 4”.
• Then, for each Traffic modem, connect a PP/CAT5FF7FTGY cable between each CRS-516
TMI and its corresponding Traffic Modem as follows:
o
CRS-516 TMI RJ-45 port labeled “Port 2” through “Port 4” to
o
Traffic Modem RJ-45 port labeled “J5 | DATA” or “J6 | DATA”.
