Highly-scalable, the EtherHaul products are software-upgradable to support future
Layer 2.5/3 networking and routing capabilities as networks evolve to flat-IP topologies.
The EtherHaul products features advanced adaptive modulation, bandwidth and coding
- allowing operators to maintain, prioritize, and verify QoS in all weather conditions,
while achieving maximum (up to 99.999%) link availability for prioritized services such
as voice signaling and Sync.
Offering easy and low cost all-outdoor installation and a small form factor, the
EtherHaul products are also environmentally-friendly - boasting a small system and
antenna footprint with especially low power consumption.
The EtherHaul systems are High-capacity Gigabit Ethernet backhaul, with advanced
networking capabilities, at the lowest TCO in the industry. EtherHaul enables mobile
operators to profitably and reliably provide data intensive services. Provided by Siklu,
the pioneer in silicon based mm-waves backhaul systems, EtherHaul systems are the
perfect choice for future proof investment.
1.1 Main Features
Siklu’s EtherHaul wireless backhaul radio link operates in the new V -band and E-band
spectrum, which provides clear technological and economic advantages over the
existing lower frequency bands. Taking advantage of the new spectrum, the EtherHaul
enables easy migration to support Gigabit throughput, enabling operators to enhance
bandwidth capacity on a “pay as you grow” basis. Supporting point-to-point, daisy-
chain, ring, and mesh configurations, the EtherHaul system offers carrier class
availability and services.
The following are some of the main features of the EtherHaul (availability of features
depends on platform):

2 Installing the EtherHaul System
This chapter describes how to install and perform the basic setup for EtherHaul outdoor
unit (ODU) in an EtherHaul wireless network, including:
Preparing the Site
EtherHaul Package Content
Unpacking the EtherHaul
Required Tools
Preparing for Installation
Mounting the EtherHaul
Installing the ODU with a Two Foot Antenna
Connecting the Cables
System LEDs
Aligning the Antenna
Link Up Verification
The installation of the EtherHaul system is followed by initial system setup that will be
described in the next chapter.
Caution:
The installation and maintenance of the EtherHaul link should only be done by
service personnel who are properly trained and certified to carry out such
activities.
Caution:
It is the responsibility of the installer to insure that when using the outdoor
antenna kits in the United States (or where FCC rules apply), only those
antennas certified with the product are used. The use of any antenna other
than those certified with the product is expressly forbidden in accordance to
FCC rules CFR47 part 15.204.
2.1 Preparing the Site
Carefully select and prepare each EtherHaul ODU site to make device installation and
configuration as simple and trouble-free as possible. During site selection and
preparation, always consider the long-term needs of both your network and your
applications.

EH-1200F Installation Manual
Page 18
2.1.1 Physical and Environmental Requirements
Each EtherHaul ODU site should adhere to the following requirements:
There must be a clear, unobstructed line-of-sight between ODU.
The EtherHaul ODU should be mounted on a fixed, stable, permanent
structure. A reinforced steel mounting pole is required, with a diameter
measuring from 2-4 inches (1ft antenna) or 2-4.5 inches (2ft antenna).
Caution:
Do not mount the EtherHaul device on a structure that is temporary or easily moved.
Doing so may result in poor service or equipment damage.
You must mount the EtherHaul ODU in a site that is easily accessible to
authorized personnel, and only authorized personnel.
Operating temperature: between -45° and +55°C.
Relative humidity: 0 to 100%.
Maximum altitude: 4,500m.
Ingress Protection rating: IP67.
2.1.2 Cabling Requirements
Ensure that your power connection cable matches the EtherHaul power
connector pin-outs.
Install the EtherHaul ODU where network connections and optional power
cabling are ready for operation and easily accessible.
All cabling connected to the ODU should be outdoor-grade, with UV
protection.
Use a two-wire cable (14-18 AWG) to connect the power supply to the ODU.
You should use shielded outdoor Cat5e cables terminated with metallic RJ45
connectors.
In order to protect indoor equipment, you must install surge protection
circuits on all copper cables on their entrance to the building.
Install the EtherHaul ODU in a location where proper electrical outdoor
grounding is readily available. Typically, the grounding connection is
attached directly to the mounting pole. If not already present, then suitable
structure-to-earth grounding connections must be created before
installation. Ground the ODU using a minimum quantity of 16AWG
grounding cable or according to local electrical code.
Caution:
Improper electrical grounding can result in excessive electromagnetic interference or
electrical discharge.

EH-1200F Installation Manual
Page 19
Siklu will not be held responsible for any malfunction or damage in the event that the
ODU is not properly grounded.

2.3 Unpacking the EtherHaul
The EtherHaul package content should be examined carefully before installation.
When you unpack the components of the EtherHaul, it is important to use care so as to
avoid damaging or scratching the antenna radome:
Do not touch the radome when unpacking the ODU.
Do not rest the ODU face down or touch the radome. It is crucial to prevent
contact between the radome and other objects.

EH-1200F Installation Manual
Page 20
2.4 Required Tools
Ensure that you have the following tools with you when performing an EtherHaul
installation:
Standard handheld digital voltage meter (DVM) with probes
Standard open-end wrench, 13 millimeter
8mm Allen key for ODU installation with 2ft antenna
Philips screwdriver, medium size head for grounding connection
Flat-head screwdriver, small size (2mm) head for DC connector
Cable ties (for securing network and optional power cables)
Cutter
Cable labeling
2.5 Preparing for Installation
The expected receive signal strength should be calculated prior to installing the link for
each antenna ODU (read from the DVM) prior to installation, based on the network link
budget.
Calculating the expected RSSI:
Where:
Ptx –ODU’s Tx Power (typically +5dBm)
Gant1 –Gain of antenna 1 (typically 35dBi)
Gant2 –Gain of antenna 2 (typically 35dBi)
LFS –Loss of Free Space = 92.45+20*Log (DKm*FGHz)+
-D - Link distance in Km
-F –Frequency in GHz
Attatm –Attenuation due to Atmospheric Gases (dB/Km)
For E-band links, the Attenuation due to Atmospheric Gases is typically
0.5dB/Km.
For V-band links, the Attenuation due to Atmospheric Gases is significantly
higher (up to 15dB/Km) and depends on the specific channel used and the exact
geographical location.
Refer to EtherHaul Link Budget Calculator for on-line calculation of expected
availability and expected RSSI.
RSSI = Ptx + Gant1 –LFS –Attatm + Gant2
