Hardware Installation
The Ethernet cables use Pins 1, 2, 3, and 6 of an 8-pin RJ45 connector. The signals of these pins are converted by the automatic
MDIX function, as shown in the following table.
Connect one side of an Ethernet cable into any switch port and connect the other side to your attached
device. The LINK/ACT LED is lit when the cable is correctly connected. Refer to
on Page 103 for descriptions of each LED indicator. Always make sure that the cables between the
switches and attached devices (for example, switch, hub, or workstation) are less than 100 meters (328
feet).
The wiring cable types and maximum cable length are as follows.
•
10BASE-T: 2-pair UTP/STP Category 3, 4, 5 cable, EIA/TIA-568 100-ohm (100 meters)
•
100BASE-TX: 2-pair UTP/STP Category 5 cable, EIA/TIA-568 100-ohm (100 meters)
•
PoE ports: 4-pair UTP/STP Category 5e / 6 cable, EIA/TIA-568 100-ohm (100 meters)
Connect the Alarm Relay Output
The RocketLinx ES7506 provides one alarm relay output. The relay contacts are energized (open) for normal operation and
will close under faulty conditions; faulty conditions can include power failure, Ethernet port link break, or other predefined
events that can be configured in the ES7506 user interface.
Wiring the alarm relay output is the same as wiring power inputs in
1.
Insert positive and negative wires into
V+ and V-.
2.
Tighten the wire-clamp screws to
prevent the wires from coming loose.
