CDM-625/625A 10/100 Ethernet System
Communication Cable Connections
1) The Redundant Modem 10/100 Ethernet port labeled “1” is always connected
to the installed CRS-510 RMI 10/100 Ethernet port labeled “Port 1.”
2) The CRS-520 TMI 10/100 Ethernet port labeled “Port 1” is always connected
to its respective Traffic Modem 10/100 Ethernet port labeled “1”.
3) Modem 10/100 Ethernet ports “2” through “4” are reserved for use as 10/100
Ethernet traffic data connections.
For 1:N connections between the CRS-500 CSU and CDM-625/625A Modems:
The CRS-500 uses 10/100 Ethernet to communicate to all modems. It also uses 10/100 Ethernet
for “pass-through” communications from the user and to/from the modems (including 10/100
Ethernet and Serial M&C).
Never directly connect to any modem for 10/100 Ethernet or Serial M&C. To access any modem
in the redundancy system, connect to the CRS-500 CSU via the CRS-530 System Controller
Ethernet (“10/100 M&C” port) or Serial (“P1 | Remote Control” port) interface.
See Figure 5-4 . Do these steps:
1. For the Redundant Modem, connect a PP/CAT5FF7FTGY cable between the Redundant
Modem and the CRS-510 RMI:
a. RJ-45 10/100 Ethernet port labeled “1” on the modem, to
b. RJ-45 10/100 Ethernet port labeled “Port 1” on the CRS-510 RMI.
2. For each Traffic Modem, 10/100 Ethernet System Communication is achieved via the
TMI/Traffic Modem route. Connect a PP/CAT5FF7FTGY cable between each Traffic
Modem and its corresponding CRS-520 TMI:
a. RJ-45 10/100 Ethernet port labeled “Port 1” on the CRS-520 TMI, to
b. RJ-45 10/100 Ethernet port labeled “1” on the modem.
