Hardware Installations and Upgrades
10. Remove the processor.

“Installing the Processor.” Otherwise, reinstall the
chassis cover.
RJ45 Serial Port Configuration
The RJ45 serial port connector can be configured to support either a DSR signal or a DCD signal.
As the server board is shipped, it is configured to support DSR signals. To change the configuration
to support DCD signals a jumper on the board must be changed. Use the following instructions to
configure your server board to support DCD signals.
1. Observe the safety and ESD precautions at the beginning of this book.
2. Turn off all peripheral devices connected to the server. Turn off the server.
3. Disconnect the AC power cord from the server.
4. Remove the server’s cover. See the documentation that accompanied your server chassis for
instructions on removing the server’s cover.
5. Locate the jumper block for the serial port. See Figure10
6. Move the jumper from the default position covering pins 1 and 3 to cover pins 2 and 4.
