NEC Server 140Rc-4 - Manual (Page 101)

Setting Up Your Server 3-29
Connection between the RJ-45 Serial Port and a Management PC (DB9), etc.
To connect equipment such as a management PC having a DB9-type serial connector to the RJ-45
serial port, use the optional "serial port conversion cable" with the "R" label attached. Be careful
not to use the other one with the "F" label attached. Set the jumper pin to "DCD+DSR" (factory-
set).
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.
