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 a FibeAir 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 (1 foot). 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 FibeAir 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.

About This Guide
This guide describes the FibeAir IP-20F installation procedures. This guide also provides
initial configuration instructions for once the hardware installation is complete.
What You Should Know
An IP-20F system consists of an IP-20F indoor unit (IDU) and one or more radio
frequency units (RFUs). This manual provides instructions for the installation of the IP-
20F IDU only. Some features described in this manual may not be available in the
current release. Consult the Release Notes for the functionality supported in the
specific release you are using.
Target Audience
This guide is intended for use by personnel of all levels certified by Ceragon personnel
such as system engineers, technicians, or supervisors.

1. FibeAir IP-20F Hardware Overview
FibeAir IP-20F is a compact unit that fits in a single rack unit, with a passive cooling
system that eliminates the need for fans. An IP-20F system consists of an IP-20F indoor
unit (IDU) and up to three radio frequency units (RFUs). The IDU is connected to each
RFU by a standard Cat-5e or preferably Cat-6/6e cable, with RF-45 connectors on the
RFU and electrical or optical fiber via SFP on the IDU. This cable transmits traffic and
management data between the IDU and the RFU. For RFU-S and RFU-D connected to
an electrical RFU interface on the IDU, this cable also provides DC -48V power to the
RFU. For RFU-S or RFU-D using an optical fiber connection, and for RFU-D-HP using an
electrical or optical fiber connection, an external DC power cable is required.
An IP-20F IDU contains:
•Three 1 GbE combo interfaces
•Two dual mode GbE or cascading combo interfaces
•Two combo (RJ-45 or SFP) radio interfaces
•An additional interface that can be configured as a combo (RJ-45 or SFP) radio
interface or a 1 GbE interface
For TDM traffic, an IP-20F IDU includes a 16 x E1/DS1 interface and two STM-1/OC-3
interfaces that require the addition of an optional rear-mounted STM-1/OC-3 module.
The STM-1/OC-3 interfaces can be used in a 1+1 STM-1/OC-3 protection configuration.
The IDU also includes two FE management interfaces, a DB9 dry contact external
alarms interface, and an RJ-45 terminal console interface for connection to a local craft
terminal. Optionally, one of the FE management interfaces can be used as an RJ-45
synchronization interface.
IP-20F receives an external supply of -48V, with a dual-feed option for power
redundancy.

1.1 Ethernet Traffic Interfaces
The front panel of the FibeAir IP-20F contains 4 x GbE combo interfaces (electrical or
optical) for Ethernet traffic. These interfaces are numbered as shown in Figure 2.
Figure 2: GbE Combo Interface Numbering
Important Note: When using electrical ports GbE 1 through GbE 4 to connect
between the IP-20F IDU and an outdoor unit such as IP-20C or
IP-20S, in areas in which severe lightning conditions are likely to
occur, it is required to use lightning protection.
GbE 1/SFP 1 and GbE 2/SFP 2 can be configured as normal Ethernet traffic interfaces or
as cascading interfaces. When operating in cascading mode, these interfaces can
handle hybrid Ethernet and Native TDM traffic, enabling operators to create links
among multiple IP-20 units in a node for multi-directional applications based on hybrid
Ethernet and Native or pseudowire TDM services..
In addition, two pairs of electrical and optical interfaces towards the right of the front
panel can be used to provide either two Ethernet interfaces or one Ethernet interface
and one radio interface:
•RFU3/SFP5 and RFU3/2.5GE5 –A combo interface that can be used as either
an SFP or RJ-45 RFU interface or an SFP or RJ-45 Ethernet interface.
•SFP6/2.5GE6 - A combo interface (SFP or RJ-45) for Ethernet.

1.2 Ethernet Management Interfaces
FibeAir IP-20F contains two FE management interfaces, which connect to a single RJ-45
physical connector on the front panel. The RJ-45 connector is the upper RJ-45 interface
in a pair of interfaces labeled MGMT/SYNC.

cable (straight or cross) can be connected to the MGMT interface.
To access both management interfaces, a special 2 x FE splitter cable can be ordered
from Ceragon.

1.4 STM-1/OC-3 Interfaces
The IP-20F includes two ch-STM-1/OC-3 ports, which can be used as a 1+1 STM-1/OC-3
protection configuration. The STM-1/OC-3 port provides an interface for up to 63 E1 or
84 DS1 lines inside a standard channelized STM-1 or OC-3 signal. Each E1/DS1 line is
transported by a VC-12 container, which behaves like a regular line interface.
Note: STM-1/OC-3 requires the addition of an optional rear-mounted
STM-1/OC-3 module, which is planned for future release.

1.5 Radio Interfaces
FibeAir IP-20F includes two combo radio interfaces (RJ-45 or SFP, RFU1 and RFU2). A
third interface can also be used as a combo radio interface (RJ-45 or SFP, RFU3).
Note: For some RFUs, PoE power can be supplied directly from the IDU via
an RJ-45 radio interface. See IDU-RFU Cable Connection on page 38.

1.6 Power Interfaces
FibeAir IP-20F receives an external supply of -48V current via a dual-feed power
interface, which can be connected to two separate power sources for power
redundancy. The IP-20F monitors the power supply for under-voltage and includes
reverse polarity protection, so that if the positive (+) and negative (-) inputs are mixed
up, the system remains shut down.
The allowed power input range for the IP-20F is -40V to -60V. An under voltage alarm
is triggered if the power goes below the allowed range, and an over voltage alarm is
triggered if the power goes above the allowed range.
