2-18 Setting Up Your System
Connection to Serial Ports
Various types of serial devices can be connected to the RJ-45 serial ports on the front and rear
panels of the server. Some devices require the setting of the jumper pin (J6A2) on the system
board to be changed according to the DCD/DSR signal specification, or they need to be
connected via an optional serial port conversion cable.
A set of two optional serial port conversion cables is provided with the server. The F (Front)
label is attached to one cable, and the R (Rear) label is attached to the other cable.
IMPORTANT:
Inter-equipment potential difference may cause a server
failure. Be sure to turn off the server and the connection-destination
equipment and disconnect the power cord before
connecting/disconnecting the cable to/from the serial port.
The figure in the next page shows the location of the jumper pin (J6A2). For instructions on how
to remove the cover and other internal components, see Chapter 7.
