3-26 Setting Up Your Server
Connection to Serial Ports
Various types of serial devices can be connected to the RJ-45 serial ports on the front or rear panels
of the server. Some devices require the setting of the jumper pin (JP25) on the baseboard to be
changed according to the DCD/DSR signal specification, or they need to be connected via an
optional serial port conversion cable.
There are two kind of cables in optional serial portconversion cable set. The "R" label is attached to
one cable (used with this server), and the "F" label is attached to the other (not used with this server).
Regarding to this cable set, contact your service representative for details.
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 below shows the location of the jumper pin (JP25). For methods to dismount the cover
and other internal components, see Chapter 9.
