3-30 Setting Up Your Server
Connection between the RJ-45 Serial Port and Device Needing a DCD/DSRSignal
If a "terminal concentrator" or the like is to be connected to the RJ-45 serial port, thoroughly read
the instruction manuals of the connection-destination equipment and cable before starting the
connection. Set the jumper pin of this server to "DCD" or "DSR" in accordance with the signal
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.
IMPORTANT:
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 equip ment 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
connected to this server.
