2.3.3 Connecting Network Cables
There are three types of connections that can be made to the DX40. They are serial,
Ethernet copper, and Ethernet fiber optic. The following sections describe each type of
connection separately.

2.3.3.1 Connecting Serial Cables

This procedure assumes that one end of the Serial device cable is already attached to the
end unit. Be aware of the serial port numbering scheme when installing the cables (see
Figure 1-1 on page 1). The ports are configured in software later on and if a device is
accidentally connected to the wrong port it will be difficult to detect.
Connect cables to the Serial ports as described below:
1.Align the DB9 connector with appropriate serial port and push gently until the
connector is completely mated to the port.
2.Tighten the two extended capture screws hand tight.
3.Make sure that the connector is not supporting the whole weight of the cable.
Providing strain relief on these cables will ensure a stable connection.
4.Return to step one above and connect the remainder of the serial cables.

2.3.3.2 Connecting Ethernet Copper Cables

If your DX40 is configured with port E2 as a standard RJ45 port, connect a shielded
Ethernet cable to the Ethernet port as follows.(see Figure 1-1 on page 1).
1.Install the RJ45 connector into the port with the clip facing up.
2.Push the RJ45 connector into the slot until you hear a click.
3.Give the cable a gentle tug to ensure that the connector clip is firmly seated.
4.Verify that the connection has been made by checking the LED associated with
this port on the DX40 chassis. It should be illuminated. If the link LED is not
illuminated verify that the equipment on the other end of the cable is powered
up and properly connected.
