The server has two serial ports, labeled SERIAL MGT and TTYA. Default Serial Connection Settings lists the default serial connection settings for both serial ports.
Table A-4 Default Serial Connection Settings
The serial management connector (labeled SER MGT) is an RJ-45 connector that can be accessed from the rear panel. This port is the default connection to the server. Use this port only for server management.
Caution - You must use a shielded Ethernet cable to maintain your server’s NEBS compliance. The cable’s shield must be grounded at both ends.

Table A-5 Serial Management RJ-45 Connector Signals
If you need to connect to the SERIAL MGT port using a cable with either a DB-9 or a DB-25 connector, use a supplied adapter to perform the crossovers given for each connector. The supplied RJ-45 to DB-9 and RJ-45 to DB-25 adapters are wired as described in RJ-45 to DB-9 Adapter Crossovers and RJ-45 to DB-25 Adapter Crossovers.
Table A-6 RJ-45 to DB-9 Adapter Crossovers
Table A-7 RJ-45 to DB-25 Adapter Crossovers
The port labeled TTYA accepts a DB-9 connector. Use this port for general purpose serial data transfers. Serial Port (TTYA) Pin Numbering shows the pin numbering of the serial port. Serial Port (TTYA) Connector Signals describes the pin signals.
