RJ-45 Serial Port

The rear RJ-45 serial port is a fully functional serial port that supports

any standard serial device and provides support for serial

concentrators. For server applications that use a serial concentrator to

access the server management features of the baseboard, a standard 8-

pin CAT-5 cable from the serial concentrator is plugged directly into

the rear RJ-45 serial port. The 8 pins of the RJ-45 connector can be

configured to match either of two pin-out standards used by serial port

devices. To accommodate either standard, the J5A2 jumper block

located directly behind the rear RJ-45 serial port must be jumpered

appropriately according to the desired standard.

Note: By default, the RJ-45 serial port is configured to support a

DSR signal.

For serial devices that require a DSR signal (default), the J5A2 jumper

must be configured in position 3-4 (See figure below, B).

For serial devices that require a DCD signal, the jumper must be in

position 1-2 (See figure below, A).

For server applications that require a DB9 serial connector, you must

use an 8-pin RJ-45-to-DB9 adapter. The following table defines the pin-

out required for the adapters to provide RS232 support.
