Connecting the Switch
Drawing No. LP0988
Remarque:
Avant de mettre sous tension le commutateur de mise à la terre, vous utilisez un
voltmètre pour vérifier qu'il n'y a pas de différence de tension entre l'alimentation de la borne de
sortie négative et le commutateur de point de mise à la masse du châssis.
If the use of shielded cables is required, it is generally recommended to only connect the shield at one end to
prevent ground loops and interfere with low level signals (i.e. thermocouples, RTD, etc.). CAT5e cables
manufactured to EIA-568A or 568B specifications are required for use with Red Lion Switches.
In the event all CAT5e patch cable distances are small (i.e. All Ethernet devices are located in the same local
cabinet and/or referenced to the same earth ground), it is permissible to use fully shielded cables terminated to
chassis ground at both ends in systems void of low level analog signals.

and

Models
For FX/FXE units, remove the dust cap from the fiber optic connectors and connect the fiber optic cables. The TX
port on the FX/FXE models should be connected to the RX port of the far end station. The RX port on the FX/FXE
versions should be connected to the TX port of the far end station
.
For 10/100 Base-TX ports, plug a Category 5E
twisted pair cable into the RJ45 connector. Connect
the other end to the far end station. Verify that the
LNK LEDs are ON once the connection has been
completed. To connect any port to another device
(end node, Switch or Repeater), use a standard
Category 5E straight through or crossover cable with
a minimum length of one meter and a maximum
length of 100 meters.
Red Lion recommends the use of pre-manufactured
CAT5E cables to ensure the best performance. If this
is not an option and users must terminate their own
ends on the CAT5E cables; one of the two color
coded standards shown to the right should be utilized.
If a user does not follow one of these two color code standards then the performance and maximum cable distance
will be reduced significantly, and may prevent the switch from establishing a link.
Warning / Avertissement
•
Creating a network loop without employing a network path protocol such as N-Ring
TM
, N-Link
TM
, or RSTP is an
illegal operation that can create a network storm which will crash the network.
•
La création d'un réseau sans boucle employant un chemin réseau protocole tels que N-Ring, N-Link, ou RSTP
est une opération illégale que peut créer une tempête du réseau qui va planter le réseau.
2.6.1.1
Connect
the
Ethernet
Cable
If you are connecting to the unit via the copper port, you will need a straight or crossover cable with two 8-pin RJ45
connectors on each end.
