Overview
The RocketLinx ES7110 and ES7110-VB are industrial Power over Ethernet (PoE)
switches with eight Fast Ethernet PoE ports and two Gigabit uplink ports to ensure a
high-bandwidth connection. The ES7110 and ES7110-VB are compliant with the IEEE
802.3af PoE standard to deliver a maximum of 15.4W per port. The ES7110 and
ES7110-VB are referred to as ES7110 in the remainder of the Guide unless
model-specific information is required.
To ensure high quality video data transmission, the ES7110 not only provides Gigabit
bandwidth uplink for large image traffic, but also supports QoS to adjust the priority of
data transfer. Using the Fault Relay, the ES7110 can automatically warn the
administrator if there are any failures. The compact IP30 rigid aluminum case allows
the ES7110 to be reliably operated in an extreme environment (-25° to 70°C). Refer to
the Comtrol web site.
Set the DIP Switch
The ES7110 has a 10-pin DIP switch located on the bottom panel to configure the Port Link
Alarm for the Ethernet ports. The following table shows the DIP switch number mapping to
the corresponding PoE and Gigabit ports as follows:
Port G2 Port G1 Port 1 Port 2 Port 3 Port 4 Port 5 Port 6 Port 7 Port 8
DIP 1 DIP 2 DIP 3 DIP 4 DIP 5 DIP 6 DIP 7 DIP 8 DIP 9 DIP 10
The port failure alarm is limited to apply on an auto-negotiation 10/100 full-duplex device.

Wire the Power
Use the following procedure to wire the power and ground.
1. Disconnect the terminal block
from the ES7110.
2. Insert the positive and negative
wires (12-24AWG) into the
PWR+ and PWR- contacts.
Relay
Note: Power should be
disconnected from the power
supply before connecting it to
the switch. Otherwise, your
screwdriver blade can
inadvertently short your terminal connections to the grounded enclosure.

3. Tighten the wire-clamp screws to prevent the wires from coming loose.
4. Plug the terminal block into the ES7110.
Wire the Relay Output and Ground
The ES7110 provides Relay Output. The relay contacts are energized (open) for normal
operation and will close under a faulty condition, such as, an Ethernet port link break.
The Relay alarm can be configured by the DIP switches.
1. Insert positive and negative
wires into Relay A and Relay B.
2. Tighten the wire-clamp screws
to prevent the wires from
coming loose.
3. Connect a ground wire
between the chassis and earth
ground using 12-24AWG wire
to ensure that the RocketLinx
ES7110 is not damaged by
noise or electrical shock.
a. Loosen the earth ground screw on the bottom of the RocketLinx ES7110 with a
screw driver.
b. Tighten the screw after the earth ground wire is connected.

DIN Rail Mount
The DIN rail clip is already attached on the rear side of the ES7110.
1. Insert the upper end of the DIN rail clip into the back of the DIN rail track from its
upper side.
2. Lightly push the bottom of the DIN rail clip into the track.
3. Verify that the DIN rail clip is tightly attached to the track.
Connect the Ethernet or PoE Ports
You can use the following information to connect Ethernet cables between the ES7110
ports and the network nodes.
Ports G1 and G2 are Gigabit Ethernet ports that support 10BASE-T,
100BASE-TX, and 1000BASE-TX.
Ports 3-10 are Fast Ethernet 10/100BASE-TX PoE ports that are IEEE 802.3af
(PoE) compliant. The Fast Ethernet ports support 10BASE-T and 100BASE-TX,
full- or half-duplex modes.
The following table shows the RJ45 pin-out assignments for the PoE and Gigabit ports:

All the Fast Ethernet ports automatically detect the signal from the connected devices
to negotiate the link speed and duplex mode. Auto MDI/MDIX allows you to connect
another switch, hub, or workstation without changing straight-through or crossover
cables. Crossover cables cross-connect the transmit lines at each end to the received
lines at the opposite end.

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

Connect one side of an Ethernet cable into any switch port and connect the other side
to your attached device. The wiring cable types and maximum cable length are as
follows.
