(3) Installation
3.1 General
All OT Systems products are thoroughly inspected, tested and securely packaged before
delivery to ensure a stable, intact and trouble-free service. Please check the equipment upon
receipt for any visible damage which may have been caused during shipping.
3.2 Package Contents
When you unpack the product package, you shall find the items listed below. Please inspect
the contents, and report any apparent damage or missing items immediately to your authorized
reseller.
Ethernet Switch
Quick Installation Guide
External power adapter & Power Cord (for Standalone Wall-mount type)
The Standalone type ET2111 Series (Fig. 3.1) can be either horizontally or vertically
wall-mounted, or fits within the most camera housings, etc. It works with an external 12VDC
power supply.
Fig. 3.1 ET2111
The Card module can be used as slide-in module to the 19” 3U high converter rack ET-C12.
See Fig.3.2(a) for the 12-slot Rack Mount Chassis which can be purchased separately; Fig.3.2(b)

3.3 Selecting a site for the Switch
As with any electric device, you should place the switch where it will not be subjected
to extreme temperatures, humidity, or electromagnetic interference. Specifically, the site
you select should meet the following requirements:
- The ambient temperature should be between -20 to +60 degrees Celsius.
- The relative humidity should be less than 95 percent, non-condensing.
- Surrounding electrical devices should not exceed the electromagnetic field (RFC)
standards.
- Make sure that the switch receives adequate ventilation.
- The power outlet should be within 1.8 meters of the switch.

DC Jack Power Input
Step 1: Connect the DC power cord to the DC jack on the rear of switch and then plug it
into a standard DC outlet.
Step 2: Disconnect the power cord if you want to shut down the switch.
3.4.2 Card module
DC Power Input
Step 1: Connect the DC power cord at the rear of ET-PSU/5V and then turn it on for
power up the card modules within the ET-C12.
Step 2: The Card Module can be removed as slide-out module form the ET-C12 (12-slot
Rack Mount Chassis). “Hot-swap” allows any module to be removed and
restored without affecting the operation of any other. Or switch off the
ET-PSU/5V to shut down all switches in the ET-C12.

3.5 Installation
This chapter gives step-by-step instructions about how to install the switch:
3.5.1 Standalone wall mount type
a) Mount the ET2111 onto a fixture or camera housings, e.g. a plank, (either on the
wall or on a flat surface) with four screws through the holes on the mounting
frame to secure it in position.
(a) Top view
(b) Side view
Fig. 3.5 Dimension of Micro type units
b) The power supply should also be mounted on the same fixture or in the proximity
for connection of the supply cables to the unit, provided that an AC power supply
socket is nearby for powering the adaptor.
c) Connect all the signal inputs and outputs at the unit with appropriate cables: fiber
optic cable for optical link and UTP/STP Cat 5 cable for Ethernet. Please refer to
Section 4.1 for the details.
d) Once the unit is powered up, check that the POWER LED on the unit is lit. If not,
check the power supply cable connections between the unit and the power
supply socket.
e) With all the signals available at the physical ports, check the status of LEDs
located on the unit. With correct status of each LED, installation is now completed
[for LEDs status, see Operational Guides on this manual’s Section (5)].

3.5.2 Card Module
a) Insert the card module into the ET-C12 chassis along the top and bottom card guides of
an empty slot and push the card into the multi-pin socket at the rear firmly. Secure with
the provided thumb screws.
b) Repeat the above procedure for all the rest card modules. Unused slots must be covered
with blank panels provided.
c) Connect all the signal inputs and outputs at the unit with appropriate cables: fiber
optic cable for optical link and UTP/STP Cat 5 cable for Ethernet. Please refer to
Section 4.1 for the details.
d) Once the unit is powered up by ET-PSU/5V, check that the POWER LED on the
unit is lit. If not, check the power supply cable connections between the chassis
and the power supply socket and the connections between the card module and
ET-C12.
e) With all the signals available at the physical ports, check the status of LEDs
located on the unit. With correct status of each LED, installation is now completed
[for LEDs status, see Operational Guides on this manual’s Section (5)].

Cabling
Step 1: First, ensure the power of the Switch and end devices are turned off.
<Note> Always ensure that the power is off before any installation.
Step 2: Prepare cable with corresponding connectors for each type of port in use.
Step 3: Consult the previous section for cabling requirements based on connectors and speed.
Step 4: Connect one end of the cable to the Switch and the other end to a desired device.
Step 5: Once the connections between two end devices are made successfully, turn on the power and the
Switch is operational.
4.2.1 The 10/100Base-TX Connector
A standard straight through cable is used for the connection between the Ethernet switch
and device. The products feature an auto-MDIX capability. For the details, Please see Appendix A
