CHAPTER 2: GETTING STARTED
2.4
Maintenance
The Multinet4 is designed to be replaced as a unit. There are no servicing requirements and
there are no user-repairable components in this device. Maintenance is limited to replacing
the unit and cleaning any fiber optic connectors and ports.
The following sections detail disconnecting all connections to the chassis, removing the
chassis, cleaning optical devices and packing the Multinet4 for return to the manufacturer.
If it is still possible to connect a terminal to the malfunctioning Multinet4 and retrieve any
configuration data from the device, do so prior to removing power.
2.4.1
Removing the Multinet4
Removing the Multinet4 entails disconnecting the power lines, disconnecting the network
cabling, and removing the chassis from the rack or other installation location. The unit can
then be packed for shipment to the manufacturer.
2.4.1.1 Disconnecting Power and Ground Lines
ELECTRICAL WARNING:
Before disconnecting either AC or DC power connections
at the Multinet4 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.
Z
Verify that power to the Multinet4 is turned off.
Z
Use a screw driver to loosen the two screws that tighten the wire
clamps in the non-polarized power connector.
Z
Remove the wires from the connector.
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.
Z
Remove the ground wire from the chassis by loosening the Ground
Lug.
2.4.1.2 Disconnecting 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.
Z
Remove all wires from the Phoenix serial ports by unscrewing the
saddle screws and pulling one wire off one port. (Label the wire
with the port number if the cable is to be reconnected at some
later time.)
Z
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.)
