Appendix D Connectivity, TCP Ports and Serial I/O
Pin-out standards exist for both DB9 and DB25 connectors; however 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
Black Box console servers come with one to forty eight serial connectors (notated SERIAL or SERIAL PORTS) for the
RS-232 serial ports:
- The LES1101A-R2 and LES1102A models have DB9 serial port connectors, all other models have RJ-45 serial
port connectors
- The RJ-45 serial ports are located on the front face of the LES1508A; on the front panel of the rackmount
LES1200/LES1300/LES1400 series; and on the rear panel of the rackmount LES1516A, LES1532A, LES1548A.
- The LES1508A, LES1516A, LES1532A, and LES1548A have Cisco straight serial pinouts on its RJ45
connectors.
- The other LES1200/LES1300/LES1400 SERIES console servers are available with a selection of alternate RJ45
pinouts (which must be specified in the part number at the time of order).
- The LES1208A-R2, LES1216A-R2, LES1232A, and LES1248A-R2 have Cisco Rolled RJ-45.
