The SER MGT RJ-45 port, located on the rear panel, provides an TIA/EIA-232 serial Oracle/Cisco standard connection to the SP. This port is the default connection to the Oracle ILOM system controller. For DTE to DTE communications, use an RJ-45 cable that is set up for a null modem configuration, in which the transmit and receive signals cross over. You can use a crossover adapter with a standard RJ-45 cable to achieve the required null modem configuration. . See Rear Panel Components (Installation).
Use this table to identify the appropriate crossover cable or adapter. In this table, the RJ-45 column represents the connector on the system and the DB-9 and DB-25 columns refer to the connector on the terminal side.
This example shows a diagram of an RJ-45 to DB-9 conversion.
