CRS-500 1:N Redundancy System
Revision 4
Configure Modems for 1:N Redundancy 7–3 MN-CRS-500
7.3 Modem Remote M&C Communication
CAUTION – You MUST NOT connect any remote M&C (serial or Ethernet)
directly to any modem connected to the 1:N Redundancy system. All modem
M&C connections (serial or Ethernet) must be made directly to the CRS-500
CSU.
For User-to-Switch or User-to-Modem serial communications addressing
schemes, see Appendix C. ADDRESSING SCHEME INFORMATION.
Figure 7-1. CRS-500 CSU Rear Panel – M&C Interfaces
Figure 7-1 shows the interfaces for establishing M&C communications between the modems and
the CRS-500 1:N Redundancy System. These connectors are provided on the CRS-530 System
Controller Module, located on the rear panel of the CRS-500 CSU:
•
Ethernet remote M&C communication between the user and modems is possible via
direct user connection to the CRS-530 RJ-45 “10/100 M&C” port.
•
Serial remote (EIA-232/485) M&C communication between the user and modems is
possible via direct user connection from a user PC serial port to the CRS-530 DB-9M “P1
| Remote Control” connector.
