Safety Precautions & Declared Material
General Equipment Precautions
Use of controls, adjustments, or performing procedures other than those
specified herein, may result in hazardous radiation exposure.
When working with an Evolution IDU, note the following risk of electric
shock and energy hazard: Disconnecting one power supply disconnects
only one power supply module. To isolate the unit completely,
disconnect all power supplies.
Machine noise information order - 3. GPSGV, the highest sound pressure
level amounts to 70 dB (A) or less, in accordance with ISO EN 7779.
Static electricity may cause body harm, as well as harm to electronic
components inside the device.
To prevent damage, before touching components inside the device, all
electrostatic must be discharged from both personnel and tools.
High Frequency Electromagnetic Fields!
Exposure to strong high frequency electromagnetic fields may cause thermal
damage to personnel. The eye (cornea and lens) is easily exposed.
Any unnecessary exposure is undesirable and should be avoided.
In radio-relay communication installations, ordinary setup for normal
operation, the general RF radiation level will be well below the safety limit.
In the antennas and directly in front of them the RF intensity normally will
exceed the danger level, within limited portions of space.
Dangerous radiation may be found in the neighborhood of open waveguide
flanges or horns where the power is radiated into space.
To avoid dangerous radiation the following precautions must be taken:
 During work within and close to the front of the antenna; make sure that
transmitters will remain turned off.
 Before opening coaxial - or waveguide connectors carrying RF power, turn
off transmitters.
 Consider any incidentally open RF connector as carrying power, until
otherwise proved. Do not look into coaxial connectors at closer than
reading distance (30 cm). Do not look into an open waveguide unless you
are absolutely sure that the power is turned off.

ESD
This equipment contains components which are sensitive to "ESD" (Electro
Static Discharge). Therefore, ESD protection measures must be observed
when touching the IDU.
Anyone responsible for the installation or maintenance of the Evolution IDU
must use an ESD Wrist Strap.
Additional precautions include personnel grounding, grounding of work
bench, grounding of tools and instruments as well as transport and storage in
special antistatic bags and boxes.
Laser
Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
The optical interface must only be serviced by qualified personnel, who are
aware of the hazards involved to repair laser products.
When handling laser products the following precautions must be taken:
 Never look directly into an open connector or optical cable.
 Before disconnecting an optical cable from the optical transmitter, the
power should be switched off. If this is not possible, the cable must be
disconnected from the transmitter before it is disconnected from the
receiver.
 When the cable is reconnected it must be connected to the receiver before
it is connected to the transmitter.

1. Introduction
This chapter provides an overview of the Evolution IP-20 Long Haul
(IP-20LH), Ceragon’s next generation multi-carrier long-haul solution.
IP-20LH is designed for ultra-high flexibility and modularity. It is optimized
for nodal deployment, with a small footprint, high density, and a high degree
of scalability and availability.
The Evolution IP-20LH enables operators to deploy high capacity, long haul
microwave systems in locations where rack space and shelter real-estate are
limited. Evolution IP-20LH supports multi-carrier solutions of up to 8+0 ABC
and IF Combining Space Diversity.
Lowering costs further, the system’s ultra-high power transmitter transmits
the highest power in the industry, and can reach longer distances using
smaller antennas. For maximum power efficiency, the Evolution IP-20LH
incorporates a dynamic biasing technique that minimizes the power
consumption of the system to the minimum required to deliver the required
Tx power while, at the same time, reducing the system’s heat dissipation. In
addition, installation labor cost and electricity consumption are reduced,
achieving an overall diminished carbon footprint.
The IP-20 series “pay-as-you-go” licensing models enable operators to build
for the future by adding capacity and functionality over time to meet the needs
of network growth without the need to add additional hardware. Additionally,
IP-20LH’s modular structure provides for the gradual expansion of network
nodes through the addition of line and radio cards, utilizing a single 1RU or
2RU chassis.

1.1 Evolution IP-20LH Hardware Options
The Evolution IP-20LH uses the IP-20N as indoor unit (IDU). The IP-20N
chassis is available in 1RU and 2RU versions, each of which supports a
common set of cards for traffic, radio interface, and management:
 Traffic/Control Card (TCC)
Can be used in 1RU and 2RU chassis
Contains 2 x 1 GbE Ethernet combo interfaces (electrical or optical)
 Radio Modem Cards (RMC)
RMC-E – Supports up to 1024 QAM (with ACM) and Header
De-Duplication. RMC-E also supports XPIC, with up to 1024 QAM
modulation. The RMC-E includes an integrated STM1/OC3-RST
interface.
 Line Cards (LIC)
Ethernet – LIC-X-E4-Elec (4x GE), with 1 GbE combo interface and
3 GbE electrical (RJ-45) interfaces
Ethernet – LIC-X-E4-Opt (4x GE) with 1 GbE combo interface and 3 GbE
optical (SFP) interfaces
TDM – LIC-T16 (16x E1)
TDM – LIC-T155 (1x ch-STM-1)
TDM – LIC-STM1/OC3-RST
The 1RU chassis supports up to four high-power radios, with redundancy
options for radio and traffic, and a dual-feed power option for power
redundancy.
The 2RU chassis supports up to eight high-power radios, with redundancy
options for management, radio, traffic, and power.

2. Evolution IP-20LH Hardware Overview
The Evolution IP-20LH is a modular unit based on a 1RU or 2RU chassis into
which a variety of cards can be inserted for traffic, radio interface,
management, and power supply. The IP-20LH backplane provides
connectivity among the slots in the chassis for management, power
distribution, and traffic aggregation.
An IP-20LH chassis and the cards it contains are managed by a Traffic Control
Card (TCC). A 2RU IP-20LH can hold two TCCs for redundancy TCCs also
include GbE Ethernet traffic and FE management interfaces.
Notes: TCC Redundancy can be implemented with any type of TCC,
but both TCCs must be the same type.
When TCC Redundancy is enabled, only the optical GbE
traffic interfaces on the TCC can be used.
Radio Module Cards (RMCs) are responsible for the interface between the
IP-20LH and the XCVRs. A 1RU IP-20LH can hold up to four RMCs. A 2RU
IP-20LH can hold up to eight RMCs.
Line Interface Cards (LICs) can be added to provide additional traffic
interfaces. Ethernet and TDM LICs can be used. A 2RU chassis can contain up
to ten LICs, up to two of which can be Ethernet LICs. A 1RU chassis can contain
up to five LICs, one of which can be an Ethernet LIC.
The IP-20LH receives an external supply of -48V via a Power Distribution Card
(PDC). A 2RU IP-20LH chassis can hold two PDCs (for card redundancy). The
PDC or PDCs distribute the power via the backplane to all the modules in the
chassis.
IP-20LH provides two basic chassis options:
 1RU – Fits in a single ETSI rack slot, with one Main Traffic and Control
Card (TCC), five universal slots for a combination of up to four Radio
Interface Cards (RMCs) and/or five Line Cards for traffic (LICs), and a
Power Distribution Card (PDC).
 2RU – Fits in two ETSI rack slots, with one or two Main Traffic and Control
Cards (TCCs), ten universal slots for a combination of up to eight Radio
Interface Cards (RMCs) and/or ten Line Cards for traffic (LICs), and two
Power Distribution Cards

2.1 Slot Population Guidelines
The figures below show the 1RU and 2RU chassis slot numbers. The mapping
of the numbered slots to the different cards is described in the tables that
follow.
Figure 1: 1RU Chassis Slot Numbering
Figure 2: 2RU Chassis Slot Numbering
The following tables list the card types that can be inserted in each slot.

2.1.1 Adjacent Pair Guidelines
It is recommended to place the same type of cards in adjacent pairs, as
follows:
 Slots 3 and 4
 Slots 5 and 6
 Slots 7 and 8 (2RU only)
 Slots 9 and 10 (2RU only)
The reason for this is that for certain features, connectivity is supported in the
backplane between these slot pairs. Even if these features are not immediately
implemented, it is recommended to adhere to these slot recommendations in
order to facilitate future upgrades.
2.1.2 Additional Slot Guidelines
 2+0 configurations are not available for cards in slots 2 and 12.
Multi-Carrier ABC
 Maximum number of carriers (i.e. RMCs/radios) is 8 (e.g., 8+0, 4+0 or
2+2).
Note: A Multi-Carrier ABC group can include up to eight radio
interfaces and up to eight STM1/OC3-RST interfaces, for a
combined total of 16 interfaces.
 There are no restrictions on slot positions for Multi-Carrier ABC.
XPIC:
 RMCs running XPIC must be placed in adjacent pairs as described above.
 XPIC configuration is not available for RMC cards in slots 2 and 12.
 2+0, 4+0, and 8+0 XPIC is supported
Note: Maximum modulation, ACM, and XPIC support varies for
specific scripts. For details, refer to the Release Notes for the
CeraOS release you are using.

2.2 Traffic Control Card (TCC)

2.7 Power Distribution Card (PDC)
Evolution IP-20LH receives an external supply of 48V current via one or two
Power Distribution Cards (PDCs). The PDC or PDCs distribute the power via
the backplane to all the modules in the chassis. Each module receives the 48V
input and regulates it down to the operating voltage required by that module.
XCVRs are powered from the PDC, via the RMC that is connected to the XCVR.
The PDC monitors the power supply for under-voltage. The PDC includes a
LED labeled ACT, which displays Green during normal operation. If the voltage
goes below -38V, the LED displays Red. When the voltage returns to -40V or
higher, the Red indication goes off and the Green indication reappears.
The PDC includes reverse polarity protection, so that if the positive (+) and
negative (-) inputs are mixed up, the system remains shutdown.
The PDC can tolerate up-to -60V, with a maximum current of 30A.
A 1RU IP-20LH includes a single power distribution card (PDC) with a dual-
feed option for power redundancy. With the dual-feed option, users can
connect two power supplies to the PDC for power redundancy.
A 2RU IP-20LH can use two PDC cards for redundancy. Each PDC provides 48V
power to all modules in the chassis via the backplane, on different lines. A
diode bridge in the modules prevents power spikes and unstable power from
the two power sources.
Figure 13: Standard PDC Detailed View

Figure 14: Dual-Feed PDC Detailed View

or, if it did go below -38V, has returned to at
least -40V or higher.
Note: If the power is below -38V, the power supply to the TCC is
automatically shut down.

2.8 Fans Module
The fans module contains four 48V fans, which can dissipate heat for systems
up to 270W. The fans draw air into one side of the chassis, and push the air
through the chassis and out the other side.
Figure 15: Fans Module Detailed View
The fan speed increases and decreases in response to the temperature inside
the chassis. When the temperature rises, the fan speed increases, and when
the temperature decreases, the fan speed decreases. The fan speed never
decreases below a minimum level regardless of temperature.

2.9 Filter Tray Overview
A filter is offered as optional equipment. If a filter tray is not ordered, the
chassis is equipped with a blank filter slot cover.

Figure 49: Single Power Source – Single IDU

14 If there is a second IDU chassis in the equipment rack, connect bridging
wires between fuses number 1 and 2.
Figure 50: Single Power Source – Two IDUs
15 If one of the PDCs has a dual power feed (such that fuse 11 is in use),
connect a second power cable, part number AWZP36, to the inputs of fuse
number 11 and to a second 48 VDC power source.
16 If there is a second IDU chassis in the equipment rack and both have dual
power feed (such that both fuses 11 and 12 are in use), connect bridging
wires between fuses number 1 and 2 and between fuses 11 and 12.
6.1.2 System Marking
Mark the system components as follows:
 XCVR - "Dir. No" and "Channel No" are used for identification of RMC-E
card in the IDU chassis and XCVR devices (see the cable marking and
channel identification map).
Figure 51: XCVR Label

 Cables - IDU power cables are marked on each end with the number of the
circuit breaker to which it is connected. XCVR-IDU cables are marked with
two digits on each end: The first is the system number (1 for the first
system in the rack, etc. The second digit is the channel number.
Figure 52: Cable Marking
Note: There are three different types of XCVR-IDU cable.
 Channel Identification Map - This map is used for identification of the
slot number of the RMC-E in the IDU chassis versus Channel No. and
Direction No.
Figure 53: Channel Identification Map

6.2 Split Mounting
The IDU chassis devices are mounted in an equipment rack (see Mounting the
IDU Chassis in the Rack on page 37) and the XCVR devices at a remote
(outdoor) location.
6.2.1 Hoisting the Branching Box
The following XCVR mounting options are available:
 Branching Box - The split-mount version has an outdoor branching
housing with a capacity of four XCVRs, with the options of IFC Space
Diversity and XPIC.
 Two Branching Boxes - It is possible to connect two outdoor branching
boxes, enabling the use of up to eight XCVRs on a single polarization.
 Two Branching Boxes with Dual Polarized Antennas – It is possible to
connect two boxes with dual polarized antennas enabling up to four
XCVRs per polarization; eight XCVRs in total.
In split-mount configuration, the indoor and outdoor parts of the system are
connected via coaxial cable. This eliminates the need for an expensive
waveguide, while still providing the convenience and interface accessibility of
an all-indoor system.
The following figure illustrates XCVR devices installed on a pole using a
branching box.
Figure 54: Split Mount System, 4+0
As the weight of 2 or 4 XCVRs is significant, use a hoist to mount the devices.

Strength is activated, the password must meet the following criteria:
Password length must be at least eight characters.
Password must include characters of at least three of the following
character types: lower case letters, upper case letters, digits, and
special characters. For purposes of meeting this requirement, upper
case letters at the beginning of the password and digits at the end of
the password are not counted.
The last five passwords you used cannot be reused.
4 Click Apply.
In addition to the Admin password, there is an additional password protected
user account, “root user”, which is configured in the system. The root user
password and instructions for changing this password are available from
Ceragon Customer Support. It is strongly recommended to change this
password.

9.4 Configuration
Before connection over the radio hop is established, it is of high importance
that the elements are assigned a dedicated IP address, according to an IP plan
for the total network.
Note: If connection over the hop is established with identical IP
addresses, an IP address conflict will occur, and remote
connection to the element on the other side of the hop may
be lost.
By default all elements have the same IP settings:
 IP address: 192.168.1.1
 Subnet mask: 255.255.255.0
Note: After the new IP address is set, the contact with the element
will be lost. In order to reconnect, the PC must have an IP
address within the same subnet as the element.
In addition to setting the IP addresses, the following configuration steps
should be performed in order to establish basic connectivity. For a detailed
description of these procedures, refer to the User Guide for Chassis-Based
Systems: FibeAir IP-20N, IP-20A, IP-20LH, and Evolution IP-20LH.
