DSR signal (Default), the jumper block must be configured with the serial port jumper over pins
3 and 4. Pin 1 on the jumper is identified by “*”.
Note: By default, the rear RJ-45 serial port is configured to support a DSR signal. This
configuration is compatible with the Cisco standard.

Figure 10. Serial Port Configuration Jumper Location
For server applications that require a DB9 serial connector, an 8-pin RJ45-to-DB9 adapter must be used.
The following table provides the pin-out required for the adapter to provide RS-232 support. A standard
DH10-to-DB9 cable and 8-pin RJ-45 to DB9 DCD and DSR adapters are available from Intel in the Serial
Port Accessory Kit (Product Code: AXXRJ45DB92).

Note: The RJ45-to-DB9 adapter should match the configuration of the serial device used. One
of two pin-out configurations is used, depending on whether the serial device requires a DSR or
DCD signal. The final adapter configuration should also match the desired pin-out of the RJ-45
connector, as it can also be configured to support either DSR or DCD.

1-2 Serial port is configured for DCD to DTR.
3-4 Serial port is configured for DSR to DTR (default).
