APPENDIX C: Connectivity, TCP Ports & Serial I/O
Pin-out standards exist for both DB9 and DB25 connectors. There are not pin-out standards for serial
connectivity using RJ45 connectors. Most console servers and serially managed servers / router /
switches / power devices have adopted their own unique pin-out, so custom connectors and cables may
be required to interconnect your console server
.
Serial Port Pinout
Opengear's console servers come with 1 to 48 serial connectors (notated
SERIAL
or
SERIAL PORTS
) for
the RS232 serial ports:
•
The RJ45 serial ports are located on the rear panel of the rack mount IM7200 and CM7100
•
The CM7100 and ACM7000 models have Cisco Straight serial pinouts on its RJ45 connectors
•
The IM7200 has software selectable Cisco Straight or Cisco Rolled RJ45
Cisco Straight RJ45 pinout (option -X2)
Straight through RJ-45 cable to equipment such as Cisco, Juniper, SUN, and more...
