3-28 Setting Up Your Server
Connection between the RJ-45 Serial Port and a UPS
To connect a UPS 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:
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.
