Connection between the Rear Serial Port and a DCD/DSR Signal Device

If a "terminal concentrator" or similar device is to be connected to the serial port on the rear panel, thoroughly read its instruction manuals before making the cable connections. Refer to subsection "Connection to Serial Ports" earlier in this chapter in order to set the jumper pin of this server to "DCD" or "DSR". They must be set in accordance with the signal that the connection- destination equipment requires.

IMPORTANT:

!Make sure of the icon on the rear panel of the server, and be sure to connect the cable to serial port 2. 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 connected to this server.

!It is hard to press the catch of the connector with your finger that is connected to the serial port. Disconnect the connector pressing the catch with a standard screwdriver. At this time, be very careful for the screwdriver not to damage the LAN port or other ports.
