2.4.1.1Disconnecting Network Cables
The sequence for removal of the serial and Ethernet cables is not important, but it is important to note that there are active devices connected to each end of the cable.
1.Remove all of the Async DB9 connectors from the serial ports by unscrewing the two captive screws on each cable and pulling the connector off the port. (Label the connector with the port number if the cable is to be reconnected at some later time.)
2.Remove the Ethernet RJ45 connectors from the Ethernet ports by pressing on the clip on the underside of the modular connector and pulling the connector straight out. (Label the connector with the port number if the cable is to be reconnected at some later time.)
LASER WARNING: DO NOT LOOK INTO A FIBER OPTIC CABLE OR PORT! These can produce invisible light that may do serious eye damage. Always assume that fiber optic cables or ports are actively radiating light energy.
3.Following the safe handling procedures for fiber optic cables and connectors, remove any fiber optic cable connected to the Ethernet fiber ports. Immediately install dust caps on the cable end and the fiber port. (Label the connector with the port number if the cable is to be reconnected at some later time.)
2.4.1.2Disconnecting Power and Ground Lines
ELECTRICAL WARNING: Before disconnecting either AC or DC power connections at the DX40 ensure that the facility power has first been turned off. Failure to shut power off prior to removing the power connections could expose you to dangerous voltages causing injury or death.
Follow the procedure below to disconnect the power and ground lines.
1.Verify that power to the DX40 is turned off.
2.Use a screw driver to loosen the two screws that tighten the wire clamps in the
ELECTRICAL WARNING: If the wires are not to be used immediately properly insulate them to ensure that an accidental turning on of the power will not cause a short or electrical hazard.
3.Remove the ground wire from the chassis by loosening the grounding screw.
