that the connection-destination equipment needs.
The jumper settings and serial port signals of this server are as shown below. When directly
connecting the server and a terminal concentrator or the like through an RJ-45 cable, prepare the
cable according to the figure below.

„ Make sure of the icon of the server, and be sure to connect the cable
to serial port B. Be careful not to connect to a LAN port by
mistake.
„ To prevent wrong connection, write "LAN port" on a tag and put the
tag to the connector of the LAN cable that is to be connected to this
server.
„ Be sure to observe the following items to prevent damage to this
server and the peripheral device:
– When using a shielded cable (STP cable), confirm that the
connector of the connection-destination equipment is compatible
with the STP cable. Connect the equipment to the server
through an STP cable of up to 15 m.
– When using an unshielded cable (UTP cable), confirm that the
connection-destination equipment is mounted in the rack of the
server or a rack linked with the server rack. Connect the
equipment to the server through a UTP cable of up to 15 m.
– To prevent wrong connection, write "Serial port" on a tag and
put the tag to the connector of the serial cable that is to be
