1 Product Overview
The ETHERLINE ACCESS U04TP01T entry-level unmanaged POE industrial Ethernet
switch is equipped with one 10/100Base-T(X) Ethernet port and four 10/100Base-T(X) PoE
ports compliant with IEEE802.3at/af. While transmitting data over the cable, PoE port can
output up to 30 watts to PoE terminals directly, eliminating the need of additional wiring.
The ETHERLINE ACCESS U04TP01T supports wide operating temperature range of -40℃
to 75℃, IP30 rated metal housing and 24VDC dual power inputs, becoming an economical
and harsh-environment-resistant solution for the ITS, video surveillance and other automation
applications.
Note：
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his
own expense.

Caution：
As part of the heat dissipation system, the housing of the switch becomes hot while working.
Please do not touch or cover the housing while the switch is working.
3.2 Mounting
The device supports DIN-rail mounting.
Mounting Environment:
1) The temperature, humidity and power supply is within the allowable range.
2) No direct sunlight, distant from heat source and areas without strong electromagnetic
interference.
3) The switches are open type equipment for indoor use.
4) The switches are intended for use in a Pollution Degree 2 industrial environment
5) The switches are recommended to be mounted in an enclosure that provides a minimum
protection rating of IP54.
Note：
Devices should be installed and accessed by service personnel or users who have been
instructed about the reasons for the restrictions applied to the location and about any precautions
that shall be taken.
3.2.1 DIN-Rail Mounting
Step 1: Select the mounting position for the device and guarantee adequate space and heat
dissipation.
Step 2: Insert the connecting seat onto the top of the DIN rail, and push the bottom of the
device inward and upward to ensure the DIN rail fits in the connecting seat. Make
sure the device is firmly installed on the DIN rail, as shown in the following figure.

3.2.2 DIN-Rail Dismounting
Step 1: As shown in the following figure, press the device downward and move the device in
direction 1 until the bottom of the device is detached from the DIN rail.
Step 2: Pull the device upward and move the device in direction 2 until the device is removed
from the DIN rail completely.

4.1 10/100Base-T(X) Ethernet Port
Data Transmission
10/100Base-T(X) Ethernet port is equipped with RJ45 connector. The port is self-adaptive. It
can automatically configure itself to work in 10M or 100M state, full or half duplex mode. The
port can also adapt to MDI or MDI-X connection automatically. You can connect the port to a
terminal or network device with a straight-through or cross-over cable.

PoE Power Supply
The switch can serve as a Power Sourcing Equipment (PSE). While transmitting data over
the cable, the switch can provide power supply to PDs (Powered Device) through Ethernet
Port 2-5. Each POE port can output up to 30 watts, compliant with IEEE802.3af/at.

4.2 Grounding
Grounding protects the device from lightning and interference. Therefore, you must ground
the device properly. You need to ground the switch before it is powered on and disconnect
the grounding cable after the device is powered off.
There is a grounding screw (see Figure 2) on the top panel for chassis grounding. After
crimping one end of the grounding cable to a cold pressed terminal, secure the end of the
grounding cable to the grounding screw and firmly connect the other end to ground.
Note：
Cross-sectional area of the chassis grounding cable>2.5mm2; Grounding resistance<5.
4.3 Power Terminal Block
There is a power terminal block on the top panel of the device. You need to connect the power
wires to the terminal block to provide power for the device. The switch supports redundant
power supply with a 4-pin 5.08mm-spacing plug-in terminal block. When one power input is
faulty, the switch can continue operating properly, thereby improving network reliability.

Wiring and Mounting
Step 1: Ground the device properly according to section 4.2.
Step 2: Remove the power terminal block from the device.
Step 3: Insert the power wires into the power terminal block according to Table 3 and tighten
the wires.
Step 4: Plug the terminal block with the connected wires into the terminal block socket on the
device.
Step 5: Connect the other end of the power cable to an external power supply system within
the allowed power range. If the corresponding power LED on the front panel of the
switch turns on, the power supply is connected properly.
