Don’t:
• Don’t install cable taut, cables must always have
some “play” or slack in them.
• Don’t over-tighten cable ties.
• Don’t splice a cable. If a break occurs, or the
length is not long enough (under 300 feet), re-
place the entire run with an intact length.
• Don’t tie cables to electrical conduits.
• Don’t strip more than one inch from the end of
each cable when installing end connectors.
• Don’t sharply bend or kink the cable.
• Don’t mix 568A and 568B wiring at the same in-
stallation. 568B is the most common wiring.
• Don’t use excessive force when pulling cable.
RJ-45 CONNECTORS
Ethernet network cables require the use of indus-
try standard RJ-45 plugs as shown below, for the
termination of all cables:
Typical RJ-45 Connector
THE HUB
A Hub is a common connection point for devices
in a network. Hubs are commonly used to connect
segments of a LAN (Local Area Network). They
also contain multiple ports. When a data packet
arrives at one port, it is copied to the other ports
so that all segments of the LAN can see all pack-
ets.
THE SWITCH
Network Switches look nearly identical to hubs,
but a switch generally contains more intelligence
than a hub. Unlike hubs, network switches are ca-
pable of inspecting the data packets as they are
received, determining the source and destination
device of a packet, and forwarding that packet
appropriately. By delivering messages only to the
connected device that it was intended for, net-
work switches conserve network bandwidth and
offer generally better performance than hubs.
The Switch takes the signal from each computer/
Quantum™ LX and sends it to all of the other com-
puters/LX panels in your plant or office. Switches
come in several sizes, noted by the number of
ports available -- a four-port Switch can connect
four computers, an eight-port Switch can connect
up to eight computers and so on. So, if you
start with a four-port Switch but eventually
add more panels, you can buy another Switch
and connect it to the one you already have,
increasing the potential number of panels on
your network.
Typical Switch
Note: If you want to connect one computer to one
Quantum™ LX, you can avoid the switch and use a
crossover Cat 5 cable. With a crossover cable, you
directly connect one Ethernet device to the other
without a Switch. To connect more than two you
need a Switch.
Refer to the following pictorial to construct a
crossover cable:

Because of the large number of possible configurations in
an Ethernet network, you most likely will not have any type
of automated installation software. This means that you
will need to manually configure all the options. To configure
these options for the Quantum™ LX, please refer to the
next section in this manual entitled Ethernet Setup.
