Setting Up Your Server 3-27

Connection between the RJ-45 Serial Port and a Modem

To connect a modem 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.
