Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its products will be free from
defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products which have been repaired or altered by persons
other than repair personnel authorized by Advantech, or which have been subject to misuse,
abuse, accident or improper installation. Advantech assumes no liability under the terms of
this warranty as a consequence of such events.
Because of Advantech′s high quality-control standards and rigorous testing, most of our
customers never need to use our repair service. If an Advantech product is defective, it will be
repaired or replaced at no charge during the warranty period. For out-of-warranty repairs, you
will be billed according to the cost of replacement materials, service time and freight. Please
consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU speed,
Advantech products used other hardware and software used, etc.) Note anything
abnormal and list any onscreen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your manual, product, and any
helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandize
authorization) number from your dealer. This allows us to process your return more
quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement Order
Card and a photocopy proof of purchase date (such as your sales receipt) in a shippable
container. A product returned without proof of the purchase date is not eligible for
warranty service.

Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage.
1. To avoid electrical shock, always disconnect the power from your PC chassis before you
work on it. Don't touch any components on the CPU card or other cards while the PC is
on.
2. Disconnect power before making any configuration changes. The sudden rush of power
as you connect a jumper or install a card may damage sensitive electronic components.

Chapter 1 Overview
1.1 Introduction
EKI-6311GN is a feature rich wireless AP/ CPE which provides a reliable wireless
connectivity for industrial environments. The PoE injector enhances flexibility in
deployment of this AP/ CPE even where the DC power supply is hard to fulfill. As an
802.11n compliant device, EKI-6311GN provides 3 times higher data rates than legacy
802.11g devices. With the support of STP, WMM and IGMP snooping protocols, EKI-
6311GN effectively improves the reliability of wireless connectivity, especially in
applications that need high reliability and high throughput data transmission. To secure
wireless connections, EKI-6311GN encrypts data through 64/128/152-bit WEP data
encryption and also supports WPA2/WPA/802.1x for powerful security authentication.

Chapter 2 Installation
This chapter describes safety precautions and product information you have to know and check
before installing EKI-6311GN.
2.1 Preparation before Installation
Professional Installation Required
Please seek assistance from a professional installer who is well trained in the RF installation and
knowledgeable in the local regulations.
Safety Precautions
1. To keep you safe and install the hardware properly, please read and follow these safety
precautions.
2. If you are installing EKI-6311GN for the first time, for your safety as well as others’, please seek
assistance from a professional installer who has received safety training on the hazards
involved.
3. Keep safety as well as performance in mind when selecting your installation site, especially
where there are electric power and phone lines.
4. When installing EKI-6311GN, please note the following things:
♦ Do not use a metal ladder;
♦ Do not work on a wet or windy day;
♦ Wear shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.
5. When the system is operational, avoid standing directly in front of it. Strong RF fields are
present when the transmitter is on.

EKI-6311GN-User_Manual V2.1 Page 10
2.2 Installation Precautions
To keep the EKI-6311GN well while you are installing it, please read and follow these installation
precautions.
1. Users MUST use a proper and well-installed surge arrestor with the EKI-6311GN; otherwise, a
random lightening could easily cause fatal damage to EKI-6311GN.
EMD (Lightning) DAMAGE IS NOT COVERED UNDER WARRNTY.
2. Users MUST use the “Power cord & PoE Injector” shipped in the box with the EKI-
6311GN. Use of other options will cause damage to the EKI-6311GN.
3. Users MUST power off the EKI-6311GN first before connecting the external antenna to it. Do
not switch from built-in antenna to the external antenna from WEB management without
physically attaching the external antenna onto the EKI-6311GN; otherwise, damage might be
caused to the EKI-6311GN itself.
2.3 Hardware Installation
Connect up
1. The bottom of the EKI-6311GN is a movable cover. Grab the cover and pull it back harder to
take it out as the figure shown below.
Figure 3 Move the Cover
2. Plug a standard Ethernet cable into the RJ45 port.

EKI-6311GN-User_Manual V2.1 Page 11
Figure 4 Cable Connection
3. Slide the cover back to seal the bottom of the EKI-6311GN.
Figure 5 Seal the Bottom
4. Plug the power cord into the DC port of the PoE injector as the following right picture shows.
Figure 6 Connect to PoE Injector
5. Plug the other side of the Ethernet cable as shown in Step 3 into the PoE port of the PoE
injector and get the complete set ready.

2.4 Pole Mounting
Pole Mounting
1. Turn the EKI-6311GN over. Put the pole mounting ring through the middle hole of it. Note that
you should unlock the pole mounting ring with a screw driver before putting it through EKI-
6311GN as the following right picture shows.
Figure 8 Pole Mounting – Step 1
2. Mount EKI-6311GN steadily to the pole by locking the pole mounting ring tightly.
Figure 9 Pole Mounting – Step 2
3. Now you have completed the hardware installation of EKI-6311GN.
