A.3 Serial Ports

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 

A.3.1 Serial Management Port

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.

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.
