ET4222PpH-S-DR
Hardened IP CCTV Self-Configured
Switch with PoE+/PSE
This quick start guide describes how to install and use the Self-Configured Hardened Ethernet Switch with PoE+.
This is the Switch of choice for harsh environments.
4-port 10/100/1000Base-T(PoE+) + 2-port 1000Base-X SFP Ethernet
Overview
The ET4222PpH-S-DR product is a Self-Configured Hardened Ethernet switch which provides 4 port
10/100/1000Base-TX + 2x1000Base-FX SFP port. The 10/100/1000Base-TX ports supports PoE+
(Power Sourcing Equipment) and compliant with IEEE 802.3at.
Comply with IEEE 802.3 10Base-T, IEEE802.3u 100Base-TX/FX, IEEE 802.3x, and IEEE802.3at. The
product will provide PoE power to any IEEE802.3at/af compliant network device. It supports IGMP
snooping which significantly saves the network bandwidth and reduces network load. With its reliable
design and ease of use, the product is a great choice for integrating networks consisting of network
devices such as IP cameras and wireless access points between remote locations.
General
To ensure trouble free transportation and storage, all OT Systems products must be thoroughly inspected,
tested and well packed before delivery. Check the product upon receipt for any visible damage which may
have been caused during shipping.

Installation
SFP Optical Module
You can select different SFP modules as required (Please refer to our SFP Ordering Options for the
appropriate module).
To insert/remove the SFP, the procedures are as follows:
1. On the front panel, insert the SFP module into the SFP port until it is securely locked.
2. Connect the optical fiber (1/2 core) to the LC connector(s) of the SFP.
3. To remove the SFP module, press down the lock of the LC connector of the optical fiber to pull out the
fiber cable.
4. Pull down the SFP lever and hold its position. Pull out the SFP module from the SFP port.

DIN Rail Installation
ET4222PpH-S-DR can be installed on a DIN rail. Installation steps are as follows:
part
1. Put the switch close to the
DIN rail track. Lock the upper
part of the DIN rail clip on the
upper side of the track.

part
2. Press the switch until
the metal part move
downward and a “click”
sound is heard.
3. The metal part is then moved
back to its original position. The
switch is securely locked on the
track. The installation is
completed.
Removal:
1. Pull down the metal part, pull out the lower part of the DIN rail clip until it leaves the track.
2. Lift up the upper part of the clip until the switch separate from the track.
Wall Mount Installation
1. Remove the screws to
take out the DIN rail clip
from the switch.

2. Tighten the screws to fix the
wall mount plate and the switch
together.
3. Mount the switch on the wall
or on a flat surface with 2 screws
piercing through the mounting
holes to secure it in position.

Setup
1. Connect one end of the Ethernet cables to their corresponding ports on the product. Connect the
other end to the network equipment such as IP cameras, Switches or PCs. Insert the SFP and
connect the optical fiber cables to its connectors.
2. Connect the product with the power adapter and switch on the product, the PWR indicator should
then be ON. If it is not, please check whether the power cable is connected properly and the power
supply functions normally.
After all cables are connected, corresponding indicators will be on. Please refer to the Operational
Instructions for detail descriptions.
